## Project Overview
Hindsight is an agent memory system that provides long-term memory for AI agents using biomimetic data structures. Memories are organized as:
- **World facts**: General knowledge ("The sky is blue")
- **Experience facts**: Personal experiences ("I visited Paris in 2023")
- **Mental models**: Consolidated knowledge synthesized from facts ("User prefers functional programming patterns")

## Architecture
### Monorepo Structure
- **hindsight-api/**: Core FastAPI server with memory engine (Python, uv)
- **hindsight/**: Embedded Python bundle (hindsight-all package)
- **hindsight-control-plane/**: Admin UI (Next.js, npm)
- **hindsight-cli/**: CLI tool (Rust, cargo, uses progenitor for API client)
- **hindsight-clients/**: Generated SDK clients (Python, TypeScript, Rust)
- **hindsight-docs/**: Docusaurus documentation site
- **hindsight-integrations/**: Framework integrations (LiteLLM, OpenAI)
- **hindsight-dev/**: Development tools and benchmarks
### Core Engine (hindsight-api/hindsight_api/engine/)
- `memory_engine.py`: Main orchestrator (~170KB) for retain/recall/reflect operations
- `llm_wrapper.py`: LLM abstraction supporting OpenAI, Anthropic, Gemini, Groq, Ollama, LM Studio
- `embeddings.py`: Embedding generation (local sentence-transformers or TEI)
- `cross_encoder.py`: Reranking (local or TEI)
- `entity_resolver.py`: Entity extraction and normalization
- `query_analyzer.py`: Query intent analysis
**retain/**: Memory ingestion pipeline
- `orchestrator.py`: Coordinates the retain flow
- `fact_extraction.py`: LLM-based fact extraction from content
- `link_utils.py`: Entity link creation and management
**search/**: Multi-strategy retrieval
- `retrieval.py`: Main retrieval orchestrator
- `graph_retrieval.py`: Entity/relationship graph traversal
- `mpfp_retrieval.py`: Multi-Path Fact Propagation retrieval
- `fusion.py`: Reciprocal rank fusion for combining results
- `reranking.py`: Cross-encoder reranking
### API Layer (hindsight-api/hindsight_api/api/)
- `http.py`: FastAPI HTTP routers (~80KB) for all REST endpoints
- `mcp.py`: Model Context Protocol server implementation
Main operations:
- **Retain**: Store memories, extracts facts/entities/relationships
- **Recall**: Retrieve memories via 4 parallel strategies (semantic, BM25, graph, temporal) + reranking
- **Reflect**: Disposition-aware reasoning using memories and mental models.
### Database
PostgreSQL with pgvector. Schema managed via Alembic migrations in `hindsight-api/hindsight_api/alembic/`. Migrations run automatically on API startup.
Key tables: `banks`, `memory_units`, `documents`, `entities`, `entity_links`
### Adding Database Migrations
1. **Create a new migration file** in `hindsight-api/hindsight_api/alembic/versions/`:
- File name format: `<revision_id>_<description>.py` (e.g., `f1a2b3c4d5e6_add_new_index.py`)
- Use a unique hex revision ID (12 chars)
- Set `down_revision` to the previous migration's revision ID
2. **Migration template**:
```python
"""Description of the migration
Revision ID: f1a2b3c4d5e6
Revises: <previous_revision_id>
Create Date: YYYY-MM-DD
"""
from collections.abc import Sequence
from alembic import context, op
revision: str = "f1a2b3c4d5e6"
down_revision: str | Sequence[str] | None = "<previous_revision_id>"
branch_labels: str | Sequence[str] | None = None
depends_on: str | Sequence[str] | None = None
def _get_schema_prefix() -> str:
"""Get schema prefix for table names (required for multi-tenant support)."""
schema = context.config.get_main_option("target_schema")
return f'"{schema}".' if schema else ""
def upgrade() -> None:
schema = _get_schema_prefix()
op.execute(f"CREATE INDEX ... ON {schema}table_name(...)")
def downgrade() -> None:
schema = _get_schema_prefix()
op.execute(f"DROP INDEX IF EXISTS {schema}index_name")
```
3. **Run migrations locally**:
```bash
# Set database URL and run migrations
uv run hindsight-admin run-db-migration
# Run on a specific tenant schema
uv run hindsight-admin run-db-migration --schema tenant_xyz
```
## Key Conventions
### Code Quality
**Always run the lint script after making Python or TypeScript/Node changes:**
```bash
./scripts/hooks/lint.sh
```
This runs the same checks as the pre-commit hook (Ruff for Python, ESLint/Prettier for TypeScript).
### Memory Banks
- Each bank is an isolated memory store (like a "brain" for one user/agent)
- Banks have dispositions (skepticism, literalism, empathy traits 1-5) affecting reflect
- Banks can have background context
- Bank isolation is strict - no cross-bank data leakage
### API Design
- All endpoints operate on a single bank per request
- Multi-bank queries are client responsibility to orchestrate
- Disposition traits only affect reflect, not recall
### Control Plane API Routes
When adding or modifying parameters in the dataplane API (hindsight-api), you must also update the control plane routes that proxy to it:
1. **API Routes** (`hindsight-control-plane/src/app/api/`):
- `recall/route.ts` - proxies to `/v1/default/banks/{bank_id}/memories/recall`
- `reflect/route.ts` - proxies to `/v1/default/banks/{bank_id}/reflect`
- `memories/retain/route.ts` - proxies to `/v1/default/banks/{bank_id}/memories/retain`
- Other routes follow the same pattern
2. **Client types** (`hindsight-control-plane/src/lib/api.ts`):
- Update the TypeScript type definitions for `recall()`, `reflect()`, `retain()` etc.
3. **Checklist when adding new API parameters**:
- Add parameter extraction in the route handler (destructure from `body`)
- Pass the parameter to the SDK call
- Update the client type definition in `lib/api.ts`
- Update any UI components that need to use the new parameter
### Python Style
- Python 3.11+, type hints required
- Async throughout (asyncpg, async FastAPI)
- Pydantic models for request/response
- Ruff for linting (line-length 120)
- No Python files at project root - maintain clean directory structure
- **Never use multi-item tuple return values** - prefer dataclass or Pydantic model for structured returns
### Type Safety with Pydantic Models
**NEVER use raw `dict` types for structured data.** Always use Pydantic models:
- Use Pydantic `BaseModel` for all data structures passed between functions
- Add `@field_validator` for type coercion (e.g., ensuring datetimes are timezone-aware)
- Avoid `dict.get()` patterns - use typed model attributes instead
- Parse external data (JSON, API responses) into Pydantic models at the boundary
- This catches type errors at parse time, not deep in business logic
```python
# BAD - error-prone dict access
def process(data: dict) -> str:
return data.get("name", "") # No validation, silent failures
# GOOD - typed and validated
class UserData(BaseModel):
name: str
created_at: datetime
@field_validator("created_at", mode="before")
@classmethod
def ensure_tz_aware(cls, v):
if isinstance(v, str):
v = datetime.fromisoformat(v.replace("Z", "+00:00"))
if v.tzinfo is None:
return v.replace(tzinfo=timezone.utc)
return v
def process(data: UserData) -> str:
return data.name # Type-safe, validated at construction
```
### TypeScript Style
- Next.js App Router for control plane
- Tailwind CSS with shadcn/ui components
### Adding New API Configuration Flags
Configuration follows a hierarchical system: **Global (env vars) → Tenant (via extension) → Bank (database)**.
Fields must be categorized as either **hierarchical** (can be overridden per-tenant/bank) or **static** (server-level only).
#### Adding a New Configuration Field
1. **config.py** (`hindsight-api/hindsight_api/config.py`):
- Add `ENV_*` constant for the environment variable name (e.g., `ENV_MY_SETTING = "HINDSIGHT_API_MY_SETTING"`)
- Add `DEFAULT_*` constant for the default value
- Add field to `HindsightConfig` dataclass with type annotation
- **Mark as hierarchical or static** by adding to `_HIERARCHICAL_FIELDS` set (hierarchical) or leaving it out (static)
- Add initialization in `from_env()` method
```python
# Hierarchical field (can be overridden per-bank)
_HIERARCHICAL_FIELDS = {
...,
"my_setting", # Add here for hierarchical
}
# Static field - just don't add to _HIERARCHICAL_FIELDS
```
2. **main.py** (`hindsight-api/hindsight_api/main.py`):
- Add field to the manual `HindsightConfig()` constructor call (search for "CLI override")
3. **Use hierarchical config in MemoryEngine**:
```python
# Config is resolved automatically per bank via ConfigResolver
config_dict = await self._config_resolver.get_bank_config(bank_id, context)
value = config_dict["my_setting"]
```
4. **Use static config** (non-hierarchical):
```python
from ...config import get_config
config = get_config()
value = config.my_static_field
```
5. **Documentation** (`hindsight-docs/docs/developer/configuration.md`):
- Add to appropriate section table with Variable, Description, Default
- Mark if it's hierarchical (can be overridden per-bank)
#### Hierarchical vs Static Guidelines
**Hierarchical** (per-bank overridable):
- LLM settings (provider, model, API key, base URL)
- Operation-specific settings (retain mode, chunk size, etc.)
- Feature flags that vary by customer/bank
**Static** (server-level only):
- Infrastructure settings (database URL, port, host)
- Global limits (max concurrent operations)
- System-wide feature flags
## Environment Setup
```bash
cp .env.example .env
# Edit .env with LLM API key
# Python deps
uv sync --directory hindsight-api/
# Node deps (uses npm workspaces)
npm install
```
Required env vars:
- `HINDSIGHT_API_LLM_PROVIDER`: openai, anthropic, gemini, groq, ollama, lmstudio
- `HINDSIGHT_API_LLM_API_KEY`: Your API key
- `HINDSIGHT_API_LLM_MODEL`: Model name (e.g., o3-mini, claude-sonnet-4-20250514)
Optional (uses local models by default):
- `HINDSIGHT_API_EMBEDDINGS_PROVIDER`: local (default) or tei
- `HINDSIGHT_API_RERANKER_PROVIDER`: local (default) or tei
- `HINDSIGHT_API_DATABASE_URL`: External PostgreSQL (uses embedded pg0 by default)
- `HINDSIGHT_API_ENABLE_BANK_CONFIG_API`: Enable per-bank config API (default: false, disabled for security)

### Code Style
We use [Ruff](https://docs.astral.sh/ruff/) for Python linting and formatting, and ESLint/Prettier for TypeScript.
#### Setting up git hooks (recommended)
Set up git hooks to automatically lint and format code before each commit:
```bash
./scripts/setup-hooks.sh
```
This configures git to use the hooks in `.githooks/`, which run all scripts in `scripts/hooks/` on commit. The lint hook runs in parallel:
- **Python**: `ruff check --fix`, `ruff format`, `ty check`
- **TypeScript**: `eslint --fix`, `prettier`
#### Manual linting and formatting
```bash
# Run all lints (same as pre-commit)
./scripts/hooks/lint.sh
# Or run individually for Python:
cd hindsight-api
uv run ruff check --fix . # Lint and auto-fix

## Release Process
The project uses `scripts/release.sh` for creating releases. This script automates the entire release workflow:
1. Bumps version in all components (API, clients, CLI, control plane, Helm)
2. **Regenerates OpenAPI spec and client SDKs** (Python, TypeScript, Rust)
3. Updates documentation versioning
4. Creates a commit and git tag
5. Pushes to GitHub (triggers CI/CD to publish packages)
### Usage
```bash
./scripts/release.sh <version>
```
**Example:**
```bash
./scripts/release.sh 0.5.0
```
### Important for Developers
- During development, version bumps in `__init__.py` do NOT require client regeneration
- Clients are only regenerated during releases
- Do not manually run `./scripts/generate-clients.sh` unless testing generation changes
- Client version comments will reflect the API version from the latest release

## What is Hindsight?
Hindsight is an agent memory system built to create smarter agents that learn over time. It eliminates the shortcomings of alternative techniques such as RAG and knowledge graph.
Hindsight addresses common challenges that have frustrated AI engineers building agents to automate tasks and assist users with conversational interfaces. Many of these challenges stem directly from a lack of memory.
- **Inconsistency:** Agents complete tasks successfully one time, then fail when asked to complete the same task again. Memory gives the agent a mechanism to remember what worked and what didn't and to use that information to reduce errors and improve consistency.
- **Hallucinations:** Long term memory can be seeded with external knowledge to ground agent behavior in reliable sources to augment training data.
- **Cognitive Overload:** As workflows get complex, retrievals, tool calls, user messages and agent responses can grow to fill the context window leading to context rot. Short term memory optimization allows agents to reduce tokens and focus context by removing irrelevant details.
## How Hindsight Works
![Overview](./hindsight-docs/static/img/hindsight-overview.png)
Hindsight organizes memory into four networks to mimic the way human memory works:
- **World:** Facts about the world ("The stove gets hot")
- **Experiences:** Agent's own experiences ("I touched the stove and it really hurt")
- **Opinion:** Beliefs with confidence scores ("I shouldn't touch the stove again" - .99 confidence)
- **Observation:** Complex mental models derived by reflecting on facts and experiences ("Curling irons, ovens, and fire are also hot. I shouldn't touch those either.")
Hindsight provides three simple methods to interact with the system:
- **Retain:** Provide information to Hindsight that you want it to remember
- **Recall:** Retrieve memories from Hindsight
- **Reflect:** Reflect on memories and experiences to generate new observations and insights from existing memories.
Memories in Hindsight are stored in banks (e.g. memory banks). When memories are retained, they are transformed to construct a series of search indexes, time series data, and entity/relationship graphs.
---
## Quick Start
### Docker (recommended)
```bash
export OPENAI_API_KEY=your-key
docker run -p 8888:8888 -p 9999:9999 \
-e HINDSIGHT_API_LLM_PROVIDER=openai \
-e HINDSIGHT_API_LLM_API_KEY=$OPENAI_API_KEY \
-e HINDSIGHT_API_LLM_MODEL=gpt-4o-mini \
-v $HOME/.hindsight-docker:/home/hindsight/.pg0 \
ghcr.io/vectorize-io/hindsight
```
API: http://localhost:8888
UI: http://localhost:9999
Install client:
```bash
pip install hindsight-client
# or
npm install @vectorize-io/hindsight-client
```
Python example:
```python
from hindsight import HindsightClient
client = HindsightClient(base_url="http://localhost:8888")
# Store
client.retain(bank_id="my-agent", content="Alice works at Google as a software engineer")
# Query
results = client.recall(bank_id="my-agent", query="What does Alice do?")
# Reflect
response = client.reflect(bank_id="my-agent", query="Tell me about Alice")
print(response.text)
```
### Python (embedded, no Docker)
```bash
pip install hindsight-all
```
```python
import os
from hindsight import HindsightServer, HindsightClient
with HindsightServer(
llm_provider="openai",
llm_model="gpt-4o-mini",
llm_api_key=os.environ["OPENAI_API_KEY"]
) as server:
client = HindsightClient(base_url=server.url)
client.retain(bank_id="my-agent", content="Alice works at Google")
results = client.recall(bank_id="my-agent", query="Where does Alice work?")
```
### TypeScript
```bash
npm install @vectorize-io/hindsight-client
```
```typescript
import { HindsightClient } from '@vectorize-io/hindsight-client';
const client = new HindsightClient({ baseUrl: 'http://localhost:8888' });
await client.retain('my-agent', 'Alice loves hiking in Yosemite');
const response = await client.recall('my-agent', 'What does Alice like?');
```

## Architecture & Operations
### Retain
The `retain` operation is used to push new memories into Hindsight. It tells Hindsight to _retain_ the information you pass in as an input.
```python
from hindsight_client import Hindsight
client = Hindsight(base_url="http://localhost:8888")
# Simple
client.retain(
bank_id="my-bank",
content="Alice works at Google as a software engineer"
)
# With context and timestamp
client.retain(
bank_id="my-bank",
content="Alice got promoted to senior engineer",
context="career update",
timestamp="2025-06-15T10:00:00Z"
)
```
Behind the scenes, the retain operation uses an LLM to extract key facts, temporal data, entities, and relationships. It passes these through a normalization process to transform extracted data into canonical entities, time series, and search indexes along with metadata. These representations create the pathways for accurate memory retrieval in the recall and reflect operations.
![Retain Operation](hindsight-docs/static/img/retain-operation.png)
### Recall
The recall operation is used to retrieve memories. These memories can come from any of the memory types (world, experiences, etc.)
```python
from hindsight_client import Hindsight
client = Hindsight(base_url="http://localhost:8888")
# Simple
client.recall(bank_id="my-bank", query="What does Alice do?")
# Temporal
results = client.recall(bank_id="my-bank", query="What happened in June?")
```
Recall performs 4 retrieval strategies in parallel:
- Semantic: Vector similarity
- Keyword: BM25 exact matching
- Graph: Entity/temporal/causal links
- Temporal: Time range filtering
![Retain Operation](hindsight-docs/static/img/recall-operation.png)
The individual results from the retrievals are merged, then ordered by relevance using reciprocal rank fusion and a cross-encoder reranking model.
The final output is trimmed as needed to fit within the token limit.
### Reflect
The reflect operation is used to perform a more thorough analysis of existing memories. This allows the agent to form new connections between memories which are then persisted as opinions and/or observations. When building agents, the reflect operation is a key capability to enable the agent to learn from its experiences.
For example, the `reflect` operation can be used to support use cases such as:
- An **AI Project Manager** reflecting on what risks need to be mitigated on a project.
- A **Sales Agent** reflecting on why certain outreach messages have gotten responses while others haven't.
- A **Support Agent** reflecting on opportunities where customers have questions not answered by current product documentation.
The `reflect` operation can also be used to handle on-demand question answering or analysis which require more deep thinking.
```python
from hindsight_client import Hindsight
client = Hindsight(base_url="http://localhost:8888")
client.reflect(bank_id="my-bank", query="What should I know about Alice?")
```
![Retain Operation](hindsight-docs/static/img/reflect-operation.png)
## Integrations
### OpenAI Drop-in Replacement
```python
from hindsight_openai import configure, OpenAI
configure(hindsight_api_url="http://localhost:8888", agent_id="my-assistant")
client = OpenAI(api_key="sk-...")
response = client.chat.completions.create(
model="gpt-4",
messages=[{"role": "user", "content": "What did we discuss?"}]
)
# Memory automatically recalled and stored
```
### Examples
[Examples directory](./examples) includes:
- Basic usage

**Long-term memory for AI agents.**
</div>
## Why Hindsight?
---
AI assistants forget everything between sessions. Every conversation starts from zero—no context about who you are, what you've discussed, or what the memory bank has learned. This isn't just inconvenient; it fundamentally limits what AI memory banks can do.
## What is Hindsight?
**The problem is harder than it looks:**
Hindsight™ is an agent memory system built to create smarter agents that learn over time. Most agent memory systems focus on recalling conversation history. Hindsight is focused on making agents that learn, not just remember.
- **Simple vector search isn't enough** — "What did Alice do last spring?" requires temporal reasoning, not just semantic similarity
- **Facts get disconnected** — Knowing "Alice works at Google" and "Google is in Mountain View" should let you answer "Where does Alice work?" even if you never stored that directly
- **Memory banks need opinions** — A coding assistant that remembers "the user prefers functional programming" should weigh that when making recommendations
- **Context matters** — The same information means different things to different memory banks with different personalities
<video src="https://github.com/user-attachments/assets/923b798d-3581-4897-bb62-9cfa5a931682" controls></video>
It eliminates the shortcomings of alternative techniques such as RAG and knowledge graph and delivers state-of-the-art performance on long term memory tasks.
## Memory Performance & Accuracy
Hindsight is the most accurate agent memory system ever tested according to benchmark performance. It has achieved state-of-the-art performance on the LongMemEval benchmark, widely used to assess memory system performance across a variety of conversational AI scenarios. The current reported performance of Hindsight and other agent memory solutions as of January 2026 is shown here:
![Overview](./hindsight-docs/static/img/hindsight-bench.jpg)
The benchmark performance data for Hindsight has been independently reproduced by research collaborators at the Virginia Tech [Sanghani Center for Artificial Intelligence and Data Analytics](https://sanghani.cs.vt.edu/) and The Washington Post. Other scores are self-reported by software vendors.
Hindsight is being used in production at Fortune 500 enterprises and by a growing number of AI startups.
## Adding Hindsight to Your AI Agents
The easiest way use Hindsight with an existing agent is with the LLM Wrapper. You can add memory to your agent with 2 lines of code. That will swap your current LLM client out with the Hindsight wrapper. After that, memories will be stored and retrieved automatically as you make LLM calls.
If you need more control over how and when your agent stores and recalls memories, there's also a simple API you can integrate with using the SDKs or directly via HTTP.

Hindsight solves these problems with a memory system designed specifically for AI memory banks.
## Quick Start
### Docker (recommended)
### Option 1: Docker (recommended)
Get the full experience with the API and Control Plane UI:
```bash
export OPENAI_API_KEY=sk-xxx
docker run --rm -it --pull always -p 8888:8888 -p 9999:9999 \
export OPENAI_API_KEY=your-key
docker run -p 8888:8888 -p 9999:9999 \
-e HINDSIGHT_API_LLM_PROVIDER=openai \
-e HINDSIGHT_API_LLM_API_KEY=$OPENAI_API_KEY \
-e HINDSIGHT_API_LLM_MODEL=gpt-4o-mini \
-v $HOME/.hindsight-docker:/home/hindsight/.pg0 \
ghcr.io/vectorize-io/hindsight:latest
ghcr.io/vectorize-io/hindsight
```
>API: http://localhost:8888
>UI: http://localhost:9999
- **API**: http://localhost:8888
- **Control Plane UI**: http://localhost:9999
You can modify the LLM provider by setting `HINDSIGHT_API_LLM_PROVIDER`. Valid options are `openai`, `anthropic`, `gemini`, `groq`, `ollama`, and `lmstudio`. The documentation provides more details on [supported models](https://hindsight.vectorize.io/developer/models).
### Docker (external PostgreSQL)
Then use the Python client:
```bash
export OPENAI_API_KEY=sk-xxx
export HINDSIGHT_DB_PASSWORD=choose-a-password
cd docker/docker-compose
docker compose up
pip install hindsight-client
```
>API: http://localhost:8888
>UI: http://localhost:9999
### Client
```bash
pip install hindsight-client -U
# or
npm install @vectorize-io/hindsight-client
```
#### Python
```python
from hindsight_client import Hindsight
from hindsight import HindsightClient
client = Hindsight(base_url="http://localhost:8888")
client = HindsightClient(base_url="http://localhost:8888")
# Retain: Store information
client.retain(bank_id="my-bank", content="Alice works at Google as a software engineer")
# Store memories
client.retain(bank_id="my-agent", content="Alice works at Google as a software engineer")
client.retain(bank_id="my-agent", content="Alice mentioned she loves hiking in the mountains")
# Recall: Search memories
client.recall(bank_id="my-bank", query="What does Alice do?")
# Query with temporal reasoning
results = client.recall(bank_id="my-agent", query="What does Alice do for work?")
# Reflect: Generate disposition-aware response
client.reflect(bank_id="my-bank", query="Tell me about Alice")
# Get a synthesized perspective
response = client.reflect(bank_id="my-agent", query="Tell me about Alice")
print(response.text)
```
#### Node.js / TypeScript
### Option 2: Embedded (no docker/server required)
For quick prototyping, run everything in-process:
```bash
npm install @vectorize-io/hindsight-client
```
```javascript
const { HindsightClient } = require('@vectorize-io/hindsight-client');
const main = async () => {
const client = new HindsightClient({ baseUrl: 'http://localhost:8888' });
await client.retain('my-bank', 'Alice loves hiking in Yosemite');
const results = await client.recall('my-bank', 'What does Alice like?');
console.log(results);
}
main();
```
### Python Embedded (no server required)
```bash
pip install hindsight-all -U
pip install hindsight-all
export OPENAI_API_KEY=your-key
```
```python
import os
from hindsight import HindsightServer, HindsightClient
with HindsightServer(
llm_provider="openai",
llm_model="gpt-5-mini",
llm_api_key=os.environ["OPENAI_API_KEY"]
) as server:
with HindsightServer(llm_provider="openai", llm_model="gpt-4o-mini", llm_api_key=os.environ["OPENAI_API_KEY"]) as server:
client = HindsightClient(base_url=server.url)
client.retain(bank_id="my-bank", content="Alice works at Google")
results = client.recall(bank_id="my-bank", query="Where does Alice work?")
client.retain(bank_id="my-user", content="User prefers functional programming")
response = client.reflect(bank_id="my-user", query="What coding style should I use?")
print(response.text)
```

## Use Cases
## Documentation
Hindsight is built to support conversational AI agents as well as agents that are intended to perform tasks autonomously. The ideal use case for Hindsight are agents that require a blend of these features such as AI employees that need to handle open-ended tasks, change behavior based on user feedback, and learn to perform complex tasks to automate work at a level that approximates a human work. Hindsight can be used with simple AI workflows like those built with n8n and other similar tools, but may be overkill for such applications.
### Per-User Memories and Chat History
One of the simpler use cases you can use Hindsight for is to personalize AI chatbots and other conversational agents by storing and recalling memories associated with individual users.
The requirements for this use case usually look something like this:
![Per-User Memories](./hindsight-docs/static/img/per-user-memory-requirements.png)
<video src="https://github.com/user-attachments/assets/4805e8e1-e7d1-47c6-a4f8-2344a5ec8906" controls></video>
Satisfying these requirements in Hindsight is straightforward. When new user inputs and tool calls are ingested into Hindsight using the retain operation, custom metadata can be used to enrich the new memories. Metadata provides a convenient way to isolate memories that need to be restricted to a given user. Once these are fed into the retain operation, any raw memories and mental models that get created can be filtered when retrieving relevant memories.
![Per-User Memories](./hindsight-docs/static/img/per-user-memory-howto.png)
---
## Architecture & Operations
![Overview](./hindsight-docs/static/img/hindsight-overview.webp)
Most agent memory implementation rely on basic vector search or sometimes use a knowledge graph. Hindsight uses biomimetic data structures to organize agent memories in a way that is more like how human memory works:
- **World:** Facts about the world ("The stove gets hot")
- **Experiences:** Agent's own experiences ("I touched the stove and it really hurt")
- **Mental Models:** Learned understanding of the agent's world formed by reflecting on raw memories and experiences.
Memories in Hindsight are stored in banks (i.e. memory banks). When memories are added to Hindsight, they are pushed into either the world facts or experiences memory pathway. They are then represented as a combination of entities, relationships, and time series with sparse/dense vector representations to aid in later recall.
Hindsight provides three simple methods to interact with the system:
- **Retain:** Provide information to Hindsight that you want it to remember
- **Recall:** Retrieve memories from Hindsight
- **Reflect:** Reflect on memories and experiences to generate new observations and insights from existing memories.
### Retain
The `retain` operation is used to push new memories into Hindsight. It tells Hindsight to _retain_ the information you pass in as an input.
```python
from hindsight_client import Hindsight
client = Hindsight(base_url="http://localhost:8888")
# Simple
client.retain(
bank_id="my-bank",
content="Alice works at Google as a software engineer"
)
# With context and timestamp
client.retain(
bank_id="my-bank",
content="Alice got promoted to senior engineer",
context="career update",
timestamp="2025-06-15T10:00:00Z"
)
```
Behind the scenes, the retain operation uses an LLM to extract key facts, temporal data, entities, and relationships. It passes these through a normalization process to transform extracted data into canonical entities, time series, and search indexes along with metadata. These representations create the pathways for accurate memory retrieval in the recall and reflect operations.
![Retain Operation](hindsight-docs/static/img/retain-operation.webp)
### Recall
The recall operation is used to retrieve memories. These memories can come from any of the memory types (world, experiences, etc.)
```python
from hindsight_client import Hindsight
client = Hindsight(base_url="http://localhost:8888")
# Simple
client.recall(bank_id="my-bank", query="What does Alice do?")
# Temporal
client.recall(bank_id="my-bank", query="What happened in June?")
```
Recall performs 4 retrieval strategies in parallel:
- Semantic: Vector similarity
- Keyword: BM25 exact matching
- Graph: Entity/temporal/causal links
- Temporal: Time range filtering
![Retain Operation](hindsight-docs/static/img/recall-operation.webp)
The individual results from the retrievals are merged, then ordered by relevance using reciprocal rank fusion and a cross-encoder reranking model.
The final output is trimmed as needed to fit within the token limit.
### Reflect
The reflect operation is used to perform a more thorough analysis of existing memories. This allows the agent to form new connections between memories and build a more thorough understanding of its world.
For example, the `reflect` operation can be used to support use cases such as:
- An **AI Project Manager** reflecting on what risks need to be mitigated on a project.
- A **Sales Agent** reflecting on why certain outreach messages have gotten responses while others haven't.
- A **Support Agent** reflecting on opportunities where customers have questions not answered by current product documentation.
The `reflect` operation can also be used to handle on-demand question answering or analysis which require more deep thinking.
```python
from hindsight_client import Hindsight
client = Hindsight(base_url="http://localhost:8888")
client.reflect(bank_id="my-bank", query="What should I know about Alice?")
```

# Nginx Reverse Proxy with Custom Base Path
Deploy Hindsight API under `/hindsight` (or any custom path) using Nginx reverse proxy.
## Quick Start (Published Image - API Only)
```bash
docker-compose up
```
- **API:** http://localhost:8080/hindsight/docs
- **Control Plane:** http://localhost:9999 (direct access, not proxied)
## Full Stack with Custom Base Path (Requires Build)
**Important:** You cannot rebuild from the published image with build args. You must build from source.
### Build from Source with Custom Base Path
1. **Clone the repository** (if you haven't):
```bash
git clone https://github.com/vectorize-io/hindsight.git
cd hindsight
```
2. **Build with base path**:
```bash
docker build \
--build-arg NEXT_PUBLIC_BASE_PATH=/hindsight \
-f docker/standalone/Dockerfile \
-t hindsight:custom \
.
```
3. **Update docker-compose.yml** to use your built image:
```yaml
services:
hindsight:
image: hindsight:custom # ← Change this
environment:
HINDSIGHT_API_BASE_PATH: /hindsight
NEXT_PUBLIC_BASE_PATH: /hindsight
```
4. **Update nginx.conf** to handle Control Plane routes (see below)
5. **Run**:
```bash
docker-compose up
```
### Required nginx.conf for Full Stack
Replace the current `nginx.conf` with this to proxy both API and Control Plane:
```nginx
events { worker_connections 1024; }
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
upstream hindsight_api { server hindsight:8888; }
upstream hindsight_cp { server hindsight:9999; }
server {
listen 80;
# API
location ~ ^/hindsight/(docs|openapi\.json|health|metrics|v1|mcp) {
proxy_pass http://hindsight_api;
proxy_set_header Host $http_host;
}
# Control Plane static files
location ~ ^/hindsight/_next/ {
proxy_pass http://hindsight_cp;
proxy_set_header Host $http_host;
}
# Control Plane UI
location /hindsight {
proxy_pass http://hindsight_cp;
proxy_set_header Host $http_host;
}
location = / { return 301 /hindsight; }
}
}
```
### Why Build is Required
Next.js requires `basePath` at **build time**. The published image was built without a custom base path, so you must rebuild from source with the `NEXT_PUBLIC_BASE_PATH` build arg to deploy the Control Plane under a subpath.
The API works without rebuild because `HINDSIGHT_API_BASE_PATH` is a runtime environment variable.

HINDSIGHT HELM CHART INSTALLATION GUIDE
=====================================
PREREQUISITES
-------------
- Kubernetes cluster (1.19+)
- kubectl configured
- Helm 3.x installed
- PostgreSQL database with pgvector extension (if not using bundled PostgreSQL)
BASIC INSTALLATION
------------------
1. Install with default values (requires external PostgreSQL):
helm install hindsight ./hindsight \
--set postgresql.external.host=your-postgres-host \
--set postgresql.external.password=your-password \
--set api.secrets.MEMORY_LLM_API_KEY=your-api-key
2. Install with custom values file:
helm install hindsight ./hindsight -f hindsight/values-production.yaml
3. Install in a specific namespace:
kubectl create namespace hindsight
helm install hindsight ./hindsight -n hindsight
CONFIGURATION OPTIONS
---------------------
Development setup (using values-development.yaml):
helm install hindsight ./hindsight -f hindsight/values-development.yaml
Production setup (using values-production.yaml):
helm install hindsight ./hindsight -f hindsight/values-production.yaml
Custom LLM provider:
helm install hindsight ./hindsight \
--set api.env.MEMORY_LLM_PROVIDER=openai \
--set api.env.MEMORY_LLM_MODEL=gpt-4 \
--set api.secrets.MEMORY_LLM_API_KEY=sk-your-key
Enable ingress:
helm install hindsight ./hindsight \
--set ingress.enabled=true \
--set ingress.hosts[0].host=hindsight.example.com
Enable autoscaling:
helm install hindsight ./hindsight \
--set autoscaling.enabled=true \
--set autoscaling.minReplicas=2 \
--set autoscaling.maxReplicas=10
UPGRADE
-------
Upgrade existing installation:
helm upgrade hindsight ./hindsight
Upgrade with new values:
helm upgrade hindsight ./hindsight -f hindsight/values-production.yaml
UNINSTALL
---------
Remove the Helm release:
helm uninstall hindsight
Remove with namespace:
helm uninstall hindsight -n hindsight
TESTING
-------
Test the installation with dry-run:
helm install hindsight ./hindsight --dry-run --debug
Validate templates:
helm template hindsight ./hindsight
Lint the chart:
helm lint ./hindsight
ACCESSING THE SERVICES
----------------------
Port-forward control plane:
kubectl port-forward svc/hindsight-control-plane 3000:3000
Port-forward API:
kubectl port-forward svc/hindsight-api 8888:8888
Get service URLs:
helm status hindsight
DATABASE INITIALIZATION
-----------------------
NOTE: Database migrations now run automatically when the API service starts.
You typically don't need to run migrations manually.
If you want to pre-initialize the database before deploying (optional):
kubectl run hindsight-init --rm -it --restart=Never \
--image=hindsight/api:latest \
--env="DATABASE_URL=postgresql://user:pass@host:5432/hindsight" \
-- python -c "from hindsight.migrations import run_migrations; run_migrations()"
TROUBLESHOOTING
---------------
Check pod status:
kubectl get pods -l app.kubernetes.io/name=hindsight
View logs for API:
kubectl logs -l app.kubernetes.io/component=api
View logs for control plane:
kubectl logs -l app.kubernetes.io/component=control-plane
Describe a pod:
kubectl describe pod <pod-name>
Check configuration:
kubectl get configmap hindsight-config -o yaml
kubectl get secret hindsight-secret -o yaml
NOTES
-----
- Make sure PostgreSQL has pgvector extension enabled
- Run database migrations before first use
- Configure proper resource limits for production
- Use external secrets management for production
- Enable TLS/SSL for production deployments

# Hindsight Helm Chart
Helm chart for deploying Hindsight - a temporal-semantic-entity memory system for AI agents.
## Prerequisites
- Kubernetes 1.19+
- Helm 3.0+
- PostgreSQL database (external or bundled)
## Quick Start
```bash
# Update dependencies first
helm dependency update ./helm/hindsight
# Install (PostgreSQL included by default)
export OPENAI_API_KEY="sk-your-openai-key"
helm upgrade hindsight --install ./helm/hindsight -n hindsight --create-namespace \
--set api.secrets.HINDSIGHT_API_LLM_API_KEY="$OPENAI_API_KEY"
```
To use an external database instead:
```bash
helm install hindsight ./helm/hindsight -n hindsight --create-namespace \
--set api.secrets.HINDSIGHT_API_LLM_API_KEY="sk-your-openai-key" \
--set postgresql.enabled=false \
--set postgresql.external.host=my-postgres.example.com \
--set postgresql.external.password=mypassword
```
## Installation
### Add the repository (if published)
```bash
helm repo add hindsight https://your-helm-repo.com
helm repo update
```
### Install with custom values file
Create a `values-override.yaml`:
```yaml
api:
secrets:
HINDSIGHT_API_LLM_API_KEY: "sk-your-openai-key"
postgresql:
external:
host: "my-postgres.example.com"
password: "mypassword"
```
Then install:
```bash
helm install hindsight ./helm/hindsight -n hindsight --create-namespace -f values-override.yaml
```
## Configuration
### Key Values
| Parameter | Description | Default |
|-----------|-------------|---------|
| `version` | Default image tag for all components | `0.1.0` |

| `postgresql.external.username` | Database username | `hindsight` |
| `ingress.enabled` | Enable ingress | `false` |
| `autoscaling.enabled` | Enable HPA | `false` |
### Environment Variables
All environment variables in `api.env` and `controlPlane.env` are automatically added to the respective pods. Sensitive values should go in `api.secrets` or `controlPlane.secrets`.
```yaml
api:
env:
HINDSIGHT_API_LLM_PROVIDER: "openai"
HINDSIGHT_API_LLM_MODEL: "gpt-4"
secrets:
HINDSIGHT_API_LLM_API_KEY: "your-api-key"
HINDSIGHT_API_LLM_BASE_URL: "https://api.openai.com/v1"
controlPlane:
env:
NODE_ENV: "production"
secrets: {}
```
### External Database
To connect to an external PostgreSQL database:
```yaml
postgresql:
enabled: false
external:
host: "my-postgres.example.com"
port: 5432
database: "hindsight"
username: "hindsight"
password: "your-password"
```
### Ingress

```yaml
ingress:
enabled: true
className: "nginx"
annotations:
cert-manager.io/cluster-issuer: "letsencrypt-prod"
hosts:
- host: hindsight.example.com
paths:
- path: /
pathType: Prefix
service: controlPlane
- path: /api
pathType: Prefix

# Hindsight API
**Memory System for AI Agents** — Temporal + Semantic + Entity Memory Architecture using PostgreSQL with pgvector.
Hindsight gives AI agents persistent memory that works like human memory: it stores facts, tracks entities and relationships, handles temporal reasoning ("what happened last spring?"), and forms opinions based on configurable disposition traits.
## Installation
```bash
pip install hindsight-api
```
## Quick Start
### Run the Server
```bash
# Set your LLM provider
export HINDSIGHT_API_LLM_PROVIDER=openai
export HINDSIGHT_API_LLM_API_KEY=sk-xxxxxxxxxxxx
# Start the server (uses embedded PostgreSQL by default)
hindsight-api
```
The server starts at http://localhost:8888 with:
- REST API for memory operations
- MCP server at `/mcp` for tool-use integration
### Use the Python API
```python
from hindsight_api import MemoryEngine
# Create and initialize the memory engine
memory = MemoryEngine()
await memory.initialize()
# Create a memory bank for your agent
bank = await memory.create_memory_bank(
name="my-assistant",
background="A helpful coding assistant"
)
# Store a memory
await memory.retain(
memory_bank_id=bank.id,
content="The user prefers Python for data science projects"
)
# Recall memories
results = await memory.recall(
memory_bank_id=bank.id,
query="What programming language does the user prefer?"
)
# Reflect with reasoning
response = await memory.reflect(
memory_bank_id=bank.id,
query="Should I recommend Python or R for this ML project?"
)
```
## CLI Options
```bash
hindsight-api --help
# Common options
hindsight-api --port 9000 # Custom port (default: 8888)
hindsight-api --host 127.0.0.1 # Bind to localhost only
hindsight-api --workers 4 # Multiple worker processes
hindsight-api --log-level debug # Verbose logging
```
## Configuration
Configure via environment variables:
| Variable | Description | Default |
|----------|-------------|---------|
| `HINDSIGHT_API_DATABASE_URL` | PostgreSQL connection string | `pg0` (embedded) |
| `HINDSIGHT_API_LLM_PROVIDER` | `openai`, `anthropic`, `gemini`, `groq`, `ollama`, `lmstudio` | `openai` |
| `HINDSIGHT_API_LLM_API_KEY` | API key for LLM provider | - |
| `HINDSIGHT_API_LLM_MODEL` | Model name | `gpt-4o-mini` |
| `HINDSIGHT_API_HOST` | Server bind address | `0.0.0.0` |
| `HINDSIGHT_API_PORT` | Server port | `8888` |
### Example with External PostgreSQL
```bash
export HINDSIGHT_API_DATABASE_URL=postgresql://user:pass@localhost:5432/hindsight
export HINDSIGHT_API_LLM_PROVIDER=groq
export HINDSIGHT_API_LLM_API_KEY=gsk_xxxxxxxxxxxx
hindsight-api
```
## Docker
```bash
docker run --rm -it -p 8888:8888 \
-e HINDSIGHT_API_LLM_API_KEY=$OPENAI_API_KEY \
-v $HOME/.hindsight-docker:/home/hindsight/.pg0 \
ghcr.io/vectorize-io/hindsight:latest
```
## MCP Server
For local MCP integration without running the full API server:
```bash
hindsight-local-mcp
```
This runs a stdio-based MCP server that can be used directly with MCP-compatible clients.
## Key Features
- **Multi-Strategy Retrieval (TEMPR)** — Semantic, keyword, graph, and temporal search combined with RRF fusion
- **Entity Graph** — Automatic entity extraction and relationship tracking
- **Temporal Reasoning** — Native support for time-based queries
- **Disposition Traits** — Configurable skepticism, literalism, and empathy influence opinion formation
- **Three Memory Types** — World facts, bank actions, and formed opinions with confidence scores

This middleware wraps the main FastAPI app and intercepts requests matching the

Authentication:
1. If HINDSIGHT_API_MCP_AUTH_TOKEN is set (legacy), validates against that token
2. Otherwise, uses TenantExtension.authenticate_mcp() from the MemoryEngine
- DefaultTenantExtension: no auth required (local dev)
- ApiKeyTenantExtension: validates against env var
Two modes based on URL structure:
1. Multi-bank mode (for /mcp/ root endpoint):
- Exposes all tools: retain, recall, reflect, list_banks, create_bank
- All tools include optional bank_id parameter for cross-bank operations
- Bank ID from: X-Bank-Id header or HINDSIGHT_MCP_BANK_ID env var
2. Single-bank mode (for /mcp/{bank_id}/ endpoints):
- Exposes bank-scoped tools only: retain, recall, reflect
- No bank_id parameter (comes from URL)
- No bank management tools (list_banks, create_bank)
- Recommended for agent isolation
Bank ID resolution priority:
1. URL path (e.g., /mcp/{bank_id}/) → single-bank mode
2. X-Bank-Id header → multi-bank mode
3. HINDSIGHT_MCP_BANK_ID env var → multi-bank mode (default: "default")

CONSOLIDATION_SYSTEM_PROMPT = """You are a memory consolidation system. Your job is to convert facts into durable knowledge (observations) and merge with existing knowledge when appropriate.
You must output ONLY valid JSON with no markdown code blocks or additional text. However, the "text" field within each observation should use markdown formatting (headers, lists, bold, etc.) for clarity and readability.
## EXTRACT DURABLE KNOWLEDGE, NOT EPHEMERAL STATE
Facts often describe events or actions. Extract the DURABLE KNOWLEDGE implied by the fact, not the transient state.
Examples of extracting durable knowledge:
- "User moved to Room 203" -> "Room 203 exists" (location exists, not where user is now)
- "User visited Acme Corp at Room 105" -> "Acme Corp is located in Room 105"
- "User took the elevator to floor 3" -> "Floor 3 is accessible by elevator"
- "User met Sarah at the lobby" -> "Sarah can be found at the lobby"
DO NOT track current user position/state as knowledge - that changes constantly.
DO track permanent facts learned from the user's actions.
## PRESERVE SPECIFIC DETAILS
Keep names, locations, numbers, and other specifics. Do NOT:
- Abstract into general principles
- Generate business insights
- Make knowledge generic
GOOD examples:
- Fact: "John likes pizza" -> "John likes pizza"
- Fact: "Alice works at Google" -> "Alice works at Google"
BAD examples:
- "John likes pizza" -> "Understanding dietary preferences helps..." (TOO ABSTRACT)
- "User is at Room 203" -> "User is currently at Room 203" (EPHEMERAL STATE)
## MERGE RULES (when comparing to existing observations):
1. REDUNDANT: Same information worded differently → update existing
2. CONTRADICTION: Opposite information about same topic → update with temporal markers showing change
Example: "Alex used to love pizza but now hates it" OR "Alex's pizza preference changed from love to hate"
3. UPDATE: New state replacing old state → update showing the transition with "used to", "now", "changed from X to Y"
## CRITICAL RULES:
- NEVER merge facts about DIFFERENT people
- NEVER merge unrelated topics (food preferences vs work vs hobbies)
- When merging contradictions, the "text" field MUST capture BOTH states with temporal markers:
* Use "used to X, now Y" OR "changed from X to Y" OR "X but now Y"
* DO NOT just state the new fact - you MUST show the change
- Keep observations focused on ONE specific topic per person
- The "text" field MUST contain durable knowledge, not ephemeral state
- Do NOT include "tags" in output - tags are handled automatically"""
CONSOLIDATION_USER_PROMPT = """Analyze this new fact and consolidate into knowledge.
{mission_section}
NEW FACT: {fact_text}
EXISTING OBSERVATIONS (JSON array with source memories and dates):
{observations_text}
Each observation includes:
- id: unique identifier for updating
- text: the observation content
- proof_count: number of supporting memories
- tags: visibility scope (handled automatically)
- created_at/updated_at: when observation was created/modified
- occurred_start/occurred_end: temporal range of source facts
- source_memories: array of supporting facts with their text and dates
Instructions:
1. Extract DURABLE KNOWLEDGE from the new fact (not ephemeral state)
2. Review source_memories in existing observations to understand evidence
3. Check dates to detect contradictions or updates
4. Compare with observations:
- Same topic → UPDATE with learning_id
- New topic → CREATE new observation
- Purely ephemeral → return []
Output JSON array of actions (the "text" field should use markdown formatting for structure):
[
{{"action": "update", "learning_id": "uuid-from-observations", "text": "## Updated Knowledge\n\n**Key point**: details here\n\n- Supporting detail 1\n- Supporting detail 2", "reason": "..."}},
{{"action": "create", "text": "## New Durable Knowledge\n\nDescription with **emphasis** and proper structure", "reason": "..."}}
]
Return [] if fact contains no durable knowledge.
IMPORTANT: Format the "text" field with markdown for better readability:
- Use headers, lists, bold/italic, tables where appropriate
- CRITICAL: Add blank lines before and after block elements (tables, code blocks, lists)
- Ensure proper spacing for markdown to render correctly"""
