Cognee

aid: cognee
name: Cognee
description: 'Cognee is an open-source AI memory and knowledge graph platform that enables developers to build persistent,
  structured memory for AI agents and LLM applications. The platform provides a REST API and Python/TypeScript SDKs for ingesting
  documents and data from 28+ sources, processing them through a six-stage ECL (Extract, Cognify, Load) pipeline, and storing
  the resulting entities and relationships in a hybrid graph-vector-relational store. Developers can query the knowledge graph
  using 13+ search modes including semantic graph completion, RAG completion, and temporal search. Cognee is available as
  a managed cloud service on AWS, GCP, and Azure, or as a self-hosted deployment via Docker, Modal, Railway, Fly.io, and Render.

  description: 'The Cognee REST API provides endpoints for the complete AI memory lifecycle, including data ingestion, knowledge
    graph construction, and semantic retrieval. Core endpoints cover adding raw text or documents, triggering the cognify
    pipeline that extracts entities and relationships via LLM, executing multi-mode search queries, managing datasets, and
    creating agent identities. The API uses X-Api-Key header authentication for cloud deployments and Bearer token auth for
    self-hosted instances.
