+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 and delivers state-of-the-art performance on long term memory tasks.
 
 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.
 
@@ -26,27 +25,48 @@ Hindsight addresses common challenges that have frustrated AI engineers building
 - **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
+## How is Hindsight Different From Other Memory Systems?
 
 ![Overview](./hindsight-docs/static/img/hindsight-overview.webp)
 
-Hindsight organizes memory into four networks to mimic the way human memory works:
+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")
 - **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.")
 
+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.
 
-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.
+### Agent Memory That Learns
+
+A key goal of Hindsight is to build agent memory that enables agents to learn and improve over time. This is the role of the `reflect` operation which provides the agent to form broader opinions and observations over time.
+
+For example, imagine a product support agent that is helping a user troubleshoot a problem. It uses a `search-documentation` tool it found on an MCP server. Later in the conversation, the agent discovers that the documentation returned from the tool wasn't for the product the user was asking about. The agent now has an experience in its memory bank. And just like humans, we want that agent to learn from its experience.
+
+As the agent gains more experiences, `reflect` allows the agent to form observations about what worked, what didn't, and what to do differently the next time it encounters a similar task.
 
 ---
 
+## Memory Performance & Accuracy
+
+Hindsight 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 December 2025 is shown here:
+
+![Overview](./hindsight-docs/static/img/hindsight-bench.jpg)
+
+The benchmark performance data for Hindsight and GPT-4o (full context) have been 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.
+
+A thorough examination of the techniques implemented in Hindsight and detailed breakdowns of benchmark performance are [available on arXiv](https://arxiv.org/abs/2512.12818). This research is currently being prepared for conference submission and the wider peer review process.
+
+The benchmark results from this research can be inspected in our [visual benchmark explorer](https://hindsight-benchmarks.vercel.app). As additional improvements are made to Hindsight, new benchmark data will be available for review using this same tool.

-# Memory 
+# 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`, `groq`, `gemini`, `ollama` | `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

+# **recall_memories**
+> RecallResponse recall_memories(bank_id, recall_request, authorization=authorization)
+
+Recall memory
+
+Recall memory using semantic similarity and spreading activation.
+
+The type parameter is optional and must be one of:
+- `world`: General knowledge about people, places, events, and things that happen
+- `experience`: Memories about experience, conversations, actions taken, and tasks performed
+- `opinion`: The bank's formed beliefs, perspectives, and viewpoints
+
+Set `include_entities=true` to get entity observations alongside recall results.
+
+### Example
+
+
+```python
+import hindsight_client_api
+from hindsight_client_api.models.recall_request import RecallRequest
+from hindsight_client_api.models.recall_response import RecallResponse
+from hindsight_client_api.rest import ApiException
+from pprint import pprint
+
+# Defining the host is optional and defaults to http://localhost
+# See configuration.py for a list of all supported configuration parameters.
+configuration = hindsight_client_api.Configuration(
+    host = "http://localhost"
+)
+
+
+# Enter a context with an instance of the API client
+async with hindsight_client_api.ApiClient(configuration) as api_client:
+    # Create an instance of the API class
+    api_instance = hindsight_client_api.MemoryApi(api_client)
+    bank_id = 'bank_id_example' # str | 
+    recall_request = hindsight_client_api.RecallRequest() # RecallRequest | 
+    authorization = 'authorization_example' # str |  (optional)
+
+    try:
+        # Recall memory
+        api_response = await api_instance.recall_memories(bank_id, recall_request, authorization=authorization)

+
+# **reflect**
+> ReflectResponse reflect(bank_id, reflect_request, authorization=authorization)
+
+Reflect and generate answer
+
+Reflect and formulate an answer using bank identity, world facts, and opinions.
+
+This endpoint:
+1. Retrieves experience (conversations and events)
+2. Retrieves world facts relevant to the query
+3. Retrieves existing opinions (bank's perspectives)
+4. Uses LLM to formulate a contextual answer
+5. Extracts and stores any new opinions formed
+6. Returns plain text answer, the facts used, and new opinions
+
+### Example
+
+
+```python
+import hindsight_client_api
+from hindsight_client_api.models.reflect_request import ReflectRequest
+from hindsight_client_api.models.reflect_response import ReflectResponse
+from hindsight_client_api.rest import ApiException
+from pprint import pprint

+
+# **retain_memories**
+> RetainResponse retain_memories(bank_id, retain_request, authorization=authorization)
+
+Retain memories
+
+Retain memory items with automatic fact extraction.
+
+This is the main endpoint for storing memories. It supports both synchronous and asynchronous processing via the `async` parameter.
+
+**Features:**
+- Efficient batch processing
+- Automatic fact extraction from natural language
+- Entity recognition and linking
+- Document tracking with automatic upsert (when document_id is provided)
+- Temporal and semantic linking
+- Optional asynchronous processing
+
+**The system automatically:**
+1. Extracts semantic facts from the content
+2. Generates embeddings
+3. Deduplicates similar facts
+4. Creates temporal, semantic, and entity links
+5. Tracks document metadata
+
+**When `async=true`:** Returns immediately after queuing. Use the operations endpoint to monitor progress.
+
+**When `async=false` (default):** Waits for processing to complete.
+
+**Note:** If a memory item has a `document_id` that already exists, the old document and its memory units will be deleted before creating new ones (upsert behavior).
+
+### Example
+
+
+```python
+import hindsight_client_api
+from hindsight_client_api.models.retain_request import RetainRequest
+from hindsight_client_api.models.retain_response import RetainResponse
+from hindsight_client_api.rest import ApiException

+
+# Enter a context with an instance of the API client
+async with hindsight_client_api.ApiClient(configuration) as api_client:
+    # Create an instance of the API class
