Cognee

Cognee is an AI memory engine that functions as a retrieval and reasoning core behind AI agents, replacing custom knowledge graphs and vector stores with a unified platform. It supports over 30 data types including PDFs, docs, spreadsheets, audio, and images, and integrates with multiple agentic frameworks, vector databases, and graph databases. Cognee continuously learns from feedback, updates concepts and synonyms, and executes multi-step tasks with explanations, improving accuracy and personalization over time. The platform is deployed in production across regulated industries and startups, emphasizing knowledge engineering over traditional retrieval-augmented generation (RAG) approaches.
