Universal memory runtime for AI agents

A bio-inspired cognitive memory engine — a new paradigm for Graph RAG.

Turn scattered knowledge, operational data, and history into source-linked context that your agents can inspect, explain, and reuse.

The open-source memory and observability layer for AI agents — persistent memory, loop detection, hash-chained audit trails, and a live dashboard, automatic on pip install.

Neo.mjs is a self-evolving software organism: a professional end-to-end AI engineering team whose cross-model swarm inhabits live apps via Neural Link, Active Hybrid GraphRAG, DreamService, and self-healing loops.
