What does cognee do?

cognee is an AI memory engine that transforms your data into living knowledge graphs. It ingests information from various sources including PDFs, documents, spreadsheets, audio files, and databases, then structures this data into a dynamic knowledge system that understands relationships and concepts. The platform handles 38+ different data types and integrates with popular agent frameworks like LangGraph, CrewAI, and Claude.

What sets cognee apart is its ability to learn from user feedback and improve over time. Unlike traditional RAG systems that struggle with accuracy and recall, cognee creates ontologies, updates concepts and synonyms, and executes multi-step tasks with explanations. It works with multiple vector databases, graph databases, and AI models, giving developers flexibility while maintaining a consistent interface.

This tool benefits engineering teams building AI agents that need reliable memory and reasoning capabilities. Real-world deployments include helping policymakers analyze hundreds of PDF documents, connecting 40,000 students with personalized learning content, and unifying credit card data for a major US bank. cognee is particularly valuable for applications requiring cited answers, concept relationships, and adaptive learning from user interactions.
