cognee
cognee builds an OSS knowledge engine for AI apps and AI agents. cognee turns scattered data into a self-improving memory graph. Our ECL pipeline (Extract, Cognify, Load) ingests data from 38+ sources, structures it into a knowledge graph with embeddings and relationships, and makes it searchable. The memify layer then refines this graph through feedback loops: rated responses feed back into edge weights, so the memory gets sharper with use. Cognee unifies three storage layers (relational, vector, and graph) into a single engine. It plugs into the tools teams already use: Claude Agent SDK, OpenAI Agents SDK, LangGraph, Google ADK, n8n, Amazon Neptune, Neo4j, and more. policy: https://topoteretes.notion.site/Privacy-Policy-11237007fa82807e8fced55da84276f7
