How it works

Simple to connect.
Powerful by design.

Three steps to give permanent memory to all your AIs.

01

Connect in 30 seconds

Add Pryzm as an MCP connector in Claude, ChatGPT or your favorite tool. One URL, one password — that's it.

02

Your AIs memorize

Decisions, contexts, projects, preferences — everything you want to keep is stored in your private encrypted space.

03

Instant context

At every new conversation, your AIs draw from your memory and answer with unmatched continuity.

Features

Built to last.

Semantic Search

Find everything, by meaning

Vector embeddings + HNSW index. Find any information by meaning, not exact words.

Persistence

Unlimited context

Overcome the context limits of each AI. Your conversations finally have long-term, structured, queryable memory.

Privacy

Inspired by Proton.
Built for you.

The Pryzm promise is simple and absolute: we cannot read your data. Not a policy. A technical impossibility.

Each client has their own isolated instance, their own database — inaccessible to others, and to us.

Dedicated instance — your isolated PostgreSQL database, one server per client.
EU hosting — European data centers, native GDPR compliance.
No Pryzm access — our keys don't open your vault.
Full export — export, migrate, delete at any time.
