Cognee
Cognee is an open-source AI memory platform that gives AI agents persistent long-term memory across sessions. It ingests data in any format, builds a self-hosted knowledge graph, and enables agents to recall, connect, and act with full context. It is for developers building AI agents that need reliable, evolving memory.

📦 Installation
🧰 Requirements: Python 3.10 to 3.14, an LLM API key (e.g., OpenAI), and optionally Docker for UI/MCP server.
uv pip install cognee
Alternatively, use pip:
pip install cognee
🚀 Usage
import cognee
import asyncio
async def main():
# Store permanently in the knowledge graph
await cognee.remember("Cognee turns documents into AI memory.")
# Query with auto-routing
results = await cognee.recall("What does Cognee do?")
for result in results:
print(result)
# Delete when done
await cognee.forget(dataset="main_dataset")
if __name__ == '__main__':
asyncio.run(main())
