The original title is: "Cognee: Adding Long-Term Memory to AI Applications with Knowledge Graphs"
Original: Your AI Forgets Everything. Here's How Cognee Fixes It.
Short summary
Most AI chatbots lose context between conversations due to lack of long-term memory. Cognee is an open-source memory layer using knowledge graphs to let AI remember information across sessions, unlike traditional RAG which only does similarity search. It provides simple APIs (remember, recall, improve, forget) and is ideal for AI assistants, chatbots, and coding helpers.
- •AI models don't retain information between conversations without external memory systems
- •Cognee uses knowledge graphs instead of basic similarity search, understanding relationships between facts
- •Apache-2.0 open-source with simple Python API; 27k+ GitHub stars
Generated with AI, which can make mistakes.
