Open-source framework that builds knowledge graphs from your data so AI systems can reason over connected information rather than isolated text chunks.
Cognee is an open-source framework for building knowledge graphs and memory systems for AI applications. It positions itself as the cognitive layer between raw data and LLM applications — processing unstructured content into structured, interconnected knowledge that agents can reason over.
Cognee's pipeline takes documents, conversations, or any text input and processes them through configurable steps: chunking, entity extraction, relationship identification, and graph construction. The output is a knowledge graph stored in a graph database (Neo4j by default) alongside vector embeddings for semantic search. This dual-representation — graph structure for relational queries and vectors for semantic similarity — gives you more flexible retrieval than either approach alone.
CrewAI is an open-source Python framework for orchestrating autonomous AI agents that collaborate as a team to accomplish complex tasks. You define agents with specific roles, goals, and tools, then organize them into crews with defined workflows. Agents can delegate work to each other, share context, and execute multi-step processes like market research, content creation, or data analysis. CrewAI supports sequential and parallel task execution, integrates with popular LLMs, and provides memory systems for agent learning. It's one of the most popular multi-agent frameworks with a large community and extensive documentation.
