# Prism Coder

**Give your AI agent memory that lasts — and see the cloud tokens it never had to spend.** Persistent sessions, knowledge graphs, offline tool-routing, and an auditable savings meter. Fully local and free.

Prism Coder is an [MCP server](https://modelcontextprotocol.io) that gives Claude, Cursor, and other AI tools long-term memory that survives across sessions. It ships with the open-weight `prism-coder` model fleet (2B–27B) for fast, offline tool-routing — no cloud required. And it keeps score: every call served locally is metered, so `prism savings` shows the token volume that never reached your cloud model — [measured honestly, in tokens](#local_savings--what-local-serving-actually-displaced).

**No account needed. No API keys. Runs on your machine.**  
A paid subscription adds cloud sync, higher model tiers, and team features through the [Synalux portal](https://synalux.ai).
