Built on ChromaDB vector store, it surfaces non-obvious links between notes using embeddings while keeping all data private. Includes built-in AI agent skills for OpenCode, Pi, and Claude Code, enabling users to summon an AI research assistant directly from their terminal that can query their knowledge graph, generate insights, and navigate complex knowledge bases without leaving the terminal or exposing data to external services.
