Atlas

Overview

Brain-inspired memory that stores and retrieves by meaning, not keywords. SQLite is the source of truth, LanceDB handles vectors, Transformers.js does embeddings on-device. Memories light up across 11 brain regions in a Three.js atlas. Ships as an npm package and stdio MCP server.

Highlights

• Write pipeline: extract entities → embed → dedupe → persist to SQLite + LanceDB
• Nine MCP tools for add, search, related, entities, and CRUD from any MCP client
• 3D brain view maps memories to cortical and subcortical regions
• Conservative entity linking — ambiguous matches stay separate instead of false-merging
