## Adding Hindsight to Your AI Agents
The easiest way to 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.

# Hindsight with Timescale Extensions
This Docker Compose setup provides a complete Hindsight deployment with **Timescale extensions**:
- **pgvectorscale** - DiskANN algorithm for disk-based scalable vector search
- **pg_textsearch** - High-performance BM25 text search
Both extensions are from [Timescale](https://github.com/timescale) and provide production-grade performance.
## Prerequisites
- Docker and Docker Compose installed
- OpenAI API key (or another LLM provider)
## Quick Start
```bash
# Set environment variables
export HINDSIGHT_DB_PASSWORD="your-secure-password"
export OPENAI_API_KEY="your-openai-api-key"
# Build and start
docker compose -f docker/docker-compose/timescale/docker-compose.yaml up -d --build
# Check logs
docker compose -f docker/docker-compose/timescale/docker-compose.yaml logs -f
```
**Access:**
- API: http://localhost:8888
- Control Plane: http://localhost:9999
## Stop and Clean Up
```bash
# Stop services
docker compose -f docker/docker-compose/timescale/docker-compose.yaml down
# Remove volumes (deletes all data)
docker compose -f docker/docker-compose/timescale/docker-compose.yaml down -v
```
## Configuration
### Environment Variables
| Variable | Description | Default |
|----------|-------------|---------|
| `HINDSIGHT_DB_PASSWORD` | PostgreSQL password | `hindsight_password` |
| `HINDSIGHT_DB_USER` | PostgreSQL username | `hindsight_user` |
| `HINDSIGHT_DB_NAME` | Database name | `hindsight_db` |
| `HINDSIGHT_VERSION` | Hindsight Docker image version | `latest` |
| `OPENAI_API_KEY` | OpenAI API key | (required) |
| `HINDSIGHT_API_LLM_PROVIDER` | LLM provider | `openai` |
### Why Timescale Extensions?
**pgvectorscale (DiskANN):**
- 28x lower p95 latency vs dedicated vector databases
- 16x higher query throughput at 99% recall
- 60-75% cost reduction (disk is cheaper than RAM)
- Best for large datasets (10M+ vectors)
**pg_textsearch (BM25):**
- High-performance keyword retrieval
- Native BM25 ranking algorithm
- Optimized for full-text search
## Troubleshooting
### Extensions not installed
Check if extensions are available:
```bash
docker exec -it hindsight-db-timescale psql -U hindsight_user -d hindsight_db -c "\dx"
```
You should see:
- `vector` (pgvector)
- `vectorscale` (pgvectorscale/DiskANN)
- `pg_textsearch` (BM25 search)
### Build fails
If the Docker build fails during pgvectorscale compilation:
1. Ensure you have sufficient memory (recommended: 4GB+)
2. Check Docker build logs for Rust compilation errors
3. Try building with more resources: `docker compose build --no-cache --memory 4g`
### Port conflicts
If port 5438 is already in use, modify the `ports` section in docker-compose.yaml.

# hindsight-all
All-in-one package for Hindsight - Agent Memory That Works Like Human Memory
## Quick Start
```python
from hindsight import start_server, HindsightClient
# Start server with embedded PostgreSQL
server = start_server(
llm_provider="groq",
llm_api_key="your-api-key",
llm_model="openai/gpt-oss-120b"
)
# Create client
client = HindsightClient(base_url=server.url)
# Store memories
client.put(agent_id="assistant", content="User prefers Python for data analysis")
# Search memories
results = client.search(agent_id="assistant", query="programming preferences")
# Generate contextual response
response = client.think(agent_id="assistant", query="What languages should I recommend?")
# Stop server when done
server.stop()
```
## Using Context Manager
```python
from hindsight import HindsightServer, HindsightClient
with HindsightServer(llm_provider="groq", llm_api_key="...") as server:
client = HindsightClient(base_url=server.url)
# ... use client ...
# Server automatically stops
```
## Installation
```bash
pip install hindsight-all

# 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

Without this index, queries using the array overlap operator (&&) or array

The temporal retrieval entry-point query filters memory_units by occurred_start,

planner falls back to a sequential scan of all bank rows after applying the

three most common date predicates, dramatically reducing the row set before any

"""Add covering and composite indexes to speed up link expansion graph retrieval.
Two indexes target the two bottlenecks identified by EXPLAIN ANALYZE on a 17M-row
memory_links table:
1. idx_memory_links_to_type_weight (to_unit_id, link_type, weight DESC)
The semantic incoming direction — finding facts that consider seeds as their
nearest neighbour — currently hits an expensive BitmapAnd of two separate
bitmap scans (to_unit_id bitmap ∩ link_type bitmap). A composite index
on (to_unit_id, link_type) turns this into a single index scan and reduces
latency from ~36 ms to < 5 ms per query.
2. idx_memory_links_entity_covering (from_unit_id) INCLUDE (to_unit_id, entity_id)
WHERE link_type = 'entity'
The entity co-occurrence expansion uses COUNT(DISTINCT ml.entity_id) and
joins on ml.to_unit_id. Without a covering index the planner must read
~2 500 heap pages to fetch entity_id and to_unit_id after the bitmap index
scan, adding ~230 ms of random I/O. INCLUDE adds those two columns to the
index leaf pages so the entire query can be served from the index (index-only
scan), eliminating the heap reads entirely.
Partial index (WHERE link_type = 'entity') keeps index size ~40 % smaller.
Both indexes are created with CONCURRENTLY so the migration does not block
concurrent reads or writes on memory_links. CONCURRENTLY requires running
outside a transaction block, so the migration emits an explicit COMMIT before
each statement and uses IF NOT EXISTS for idempotency.

"""Recreate idx_memory_units_source_memory_ids GIN index with fastupdate=off
GIN indexes use a "fastupdate" pending list by default: small writes are
buffered there and flushed to the main GIN tree in bulk. Flushing requires
AccessExclusiveLock on the index. Under high insert concurrency (e.g. 8
parallel pytest-xdist workers all calling retain_async) two transactions can
each trigger a flush simultaneously and deadlock.
Disabling fastupdate makes every insert write directly to the GIN tree
(slightly slower per insert, but no pending-list lock cycles).

"""Add internal_id to banks and per-(bank, fact_type) partial HNSW indexes
Revision ID: d5e6f7a8b9c0
Revises: a3b4c5d6e7f8
Create Date: 2026-03-11
This migration:
1. Adds internal_id UUID column to banks (stable identifier for index naming)
2. Drops the global HNSW index (competes with per-bank partial indexes)
3. Creates per-(bank_id, fact_type) partial HNSW indexes for all existing banks
(new banks get indexes created at bank-creation time via bank_utils.create_bank_hnsw_indexes)
Why per-(bank, fact_type) indexes:
- fact_type-only partial indexes are never chosen by the planner when bank_id is in the WHERE
clause, because the idx_memory_units_bank_id B-tree index always wins at planning time.
- Per-(bank, fact_type) partial indexes have both predicates matching → planner selects them.
- The global HNSW index competes for larger partitions (world, observation) and must be dropped.
For large deployments, create indexes CONCURRENTLY before running this migration:
SELECT internal_id, bank_id FROM banks;
-- for each bank and each fact_type in (world, experience, observation):
CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_mu_emb_{ft}_{uid16}
ON memory_units USING hnsw (embedding vector_cosine_ops)
WHERE fact_type = '{ft}' AND bank_id = '{bank_id}';
DROP INDEX CONCURRENTLY IF EXISTS idx_memory_units_embedding;

Link Expansion graph retrieval.
Expands from semantic/temporal seeds through three parallel, first-class signals
stored in memory_links:
1. Entity links — precomputed co-occurrence graph (created at retain time, bounded to
MAX_LINKS_PER_ENTITY per entity). Score = number of distinct shared
entities between the seed set and each candidate.
2. Semantic links — precomputed kNN graph (each new fact linked to its top-5 most
similar existing facts at insert time, similarity >= 0.7). Checked
in both directions since the graph is not symmetric. Score = weight.
3. Causal links — explicit causal chains (causes/caused_by/enables/prevents).
Score = weight + 1.0 (boosted as highest-quality signal).
All three signals are bounded at retain time, so no LATERAL fan-out caps are needed
at query time. Each expansion is a simple aggregation over a small result set.
For non-observation fact types the three expansions are issued as a single CTE query
(one roundtrip, one connection) with a `source` discriminator column so the Python
merge step can apply per-signal score transformations.
