Memory that stays available
r3 stores memories locally and retrieves them by meaning. The same context can be used from desktop clients, command line tools, and custom MCP integrations.
r3
Useful context beyond a single conversation
A local memory service for AI assistants. r3 combines semantic search, vector embeddings, and a knowledge graph behind an MCP interface so context can survive between sessions and tools.
“Why did we pick this database?”
SQLite was chosen for offline use.
Install
A graph underneath
Entities and relationships are extracted as memories are written, giving an assistant more than a flat list of matching text.
Source and package
The website moved here; the open-source server and npm package remain in the r3 repository.
