Your AI builds you real apps.
Ask in plain words and get a real app that remembers your stuff — the same one in Claude, ChatGPT, and on the web. No code, ever.
Free during the public beta · no credit card · your data stays yours
The same app, wherever you already work.
Connect openmcp.app once, and your apps travel with you. Claude is live in the beta today, and every app also opens at your own openmcp.app link. ChatGPT is rolling out next — it's built on an open standard, so more will follow.
Just ask. The app appears.
Tell your AI what you need, the way you'd tell a person. It designs the app, wires up every button, and hands it back ready to use — in seconds. Want it different? Ask again.
They remember your stuff.
Most AI answers vanish the moment you scroll away. These don't. Every app keeps its own memory — your budget, your habits, your lists stay put, and your AI updates them right alongside you.
Yours everywhere — and open.
The same app follows you into every AI you connect, and lives at your own web link. openmcp.app is open source under AGPL, so you can run the whole thing yourself. No lock-in, ever.
Three steps to your first app.
No setup, no code. If you can chat, you can do this — about two minutes to connect.
Connect your AI
Sign in, then add your personal openmcp.app link to Claude or ChatGPT. You only do this once.
Ask for an app
Tell your AI what you want. It builds the app right there in the chat, ready to use.

Open it again in any connected AI, or at your web link — your stuff is already inside.
