Your AI finally remembers you.

Pryzm keeps what you tell Claude, sorts it by project and finds it by meaning, even months later. If you also use ChatGPT or Cursor, they share the same memory.

Works with Claude, even on its free plan. If you also use ChatGPT, it needs a paid plan.

What Pryzm changes in your conversations.

Your AI without PryzmYour AI with Pryzm

Every new conversation starts from scratch.

It picks up where you left off.

What you said three months ago gets lost in your chat history.

It finds it by meaning, even months later.

It mixes up the old amount and the final decision.

It goes with the latest decision, and says when nothing was decided.

You paste pages of notes to give it context.

It fetches only what the question needs.

Tomorrow's meeting is yours to remember.

It brings it up as soon as you open the conversation.

With several AIs, you explain everything to each one.

They share the same memory.

97% correct answers with Pryzm, versus 94% when pasting all your notes, for about 3 times fewer tokens.

Our measurement of October 11, 2026: 32 unseen questions over fictional notes, answered by Claude Sonnet. A gap of a few points is within the bench's margin.

Frequently asked questions

Fair questions before you start.

What is Pryzm Memory, exactly?

A memory for your AI. When you tell Claude something that matters, it saves it to Pryzm, sorted by project. In a new conversation, even months later, it finds it by meaning, without you having to remember the exact words, and goes with the latest decision. From your space, you can see, correct and export everything that was saved. If you also use ChatGPT, Cursor or Perplexity, they share the same memory, through the MCP protocol.

What do I need for it to work?

An AI that accepts custom MCP connectors. Claude works even on its free plan, which allows one custom connector. ChatGPT needs a paid plan and connects from chatgpt.com. Perplexity needs Pro, Max or Enterprise. Claude Code, Cursor and other MCP clients work too. Nothing to install: paste one address into the AI's settings, then sign in to your Pryzm account.

See the setup guide
Where is my data, and who can read it?

Your memories are hosted in Germany, at Hetzner in Falkenstein. They are encrypted with a key unique to your account, in a space kept separate from other accounts. The limit: while you are signed in, the server decrypts them in memory to answer your AI, and what your AI reads goes through its provider (Anthropic, OpenAI…) under that provider's terms. Optional AI features (automatic tags, summaries) are off by default; if you turn them on in Settings, the text involved is sent to Anthropic. Pryzm doesn't sell your data or use it to train AI. Technical access to the servers is restricted and logged.

Can I stop Pryzm from saving something?

Yes. Start your message with ##: Pryzm tells your AI to save nothing from it, and the server refuses any memory that starts with ##. Card numbers, API keys and passwords are refused the same way. You can also edit or delete any memory from your space.

Why not Claude's or ChatGPT's built-in memory?

With Pryzm, you see everything your AI has saved, sorted by project, and you correct or export it whenever you like. The same memory works wherever you use Claude (claude.ai, the mobile app, Claude Code), and in ChatGPT, Cursor or Perplexity too if you use them. We recommend turning the built-in memory off: in our test, it made the AI answer from outdated information instead of checking Pryzm.

What does the free plan include?

100 memories in 1 project, with every compatible AI, no credit card. Once you reach 100 memories, new ones are no longer saved, but you can still read, search, export and delete yours. Solo (€9.99 a month, or €99.90 a year) removes these limits: unlimited memories and projects.

Can I leave with my data, or cancel?

Yes. Export your whole memory from your space as a readable JSON file, and delete your account whenever you want. Solo has no commitment: cancel from Settings → “Manage or cancel my subscription”; it takes effect at the end of the period you paid for. Export before that date: after it, access is cut off and the data is deleted 30 days later.

How is this different from Mem0 or Supermemory?

Mem0 and Supermemory are open source and can be self-hosted; both also offer an online version. Pryzm Memory is a ready-to-use service, hosted in Germany: nothing to install to give your AI a memory. If you'd rather keep everything at home, Pryzm for desktop, a free app for Windows, macOS and Linux, keeps the memory on your machine. Either way, Pryzm's engine isn't open source.
