Public beta · free

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

One app, everywhere

The same app, wherever you already work.

ClaudeChatGPTYour web link+ more coming

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.

01 · Build by asking

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.

02 · Real apps

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.

How it works

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.

Use it anywhere

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