Prism

Session memory that never leaves your machine

Your coding agent forgets everything between sessions. Prism gives it a memory that sticks: decisions, open TODOs, and changed files restored the moment you return — plus associative recall of related past work, drift detection when a long session wanders off-goal, and an on-device prism-coder model that reasons over it all without a cloud call. Works with Claude Code, Cursor, and Codex.

What it does

💾

Memory that sticks

Decisions, open TODOs, and changed files restored at the start of every session — no re-explaining context you already gave.

🧠

Associative recall

A spreading-activation graph surfaces related past work — "how did we solve this before?" without scrolling transcripts.

🔄

Drift detection

Scores recent work against the goal you started with and flags when a long session has wandered.

🤖

On-device inference

The prism-coder model fleet (2B–27B) answers locally — bounded work never needs a cloud call or an API key.

🛡

Local-only by default

SQLite on your machine. Your memory and the model reading it both stay on your device; nothing is sent anywhere unless you enable cloud sync.

🔏

Verifiable releases

Every npm release is published via trusted publishing with a signed provenance attestation — verify with npm audit signatures.
