Build your app in ChatGPT or Claude

Add Gemmein to ChatGPT or Claude once. After that, say what you want in plain words, and your AI builds the app, puts it on your private preview and shows you.

01 / WHERE IT WORKS

Where it works

AppWhere
ChatGPTOn a computer, at chatgpt.com. Works on every ChatGPT plan, Free included.
ClaudeOn claude.ai on the web, or in the Claude desktop app.
02 / ADD IT ONCE

Add it once

Copy Gemmein’s address from the setup page and add it in ChatGPT or Claude. Then sign in on app.gemmein.com and approve. You do this once; the approval lasts 30 days.

03 / THEN ASK

Then say what you want

You don’t need to mention Gemmein. Once it is added, your AI uses it on its own. Ask the way you would text a friend:

Make a booking page for my yoga studio. People pay a £10 deposit when they book.
Build a members’ area for my cooking course. £5 a month, cancel any time.
04 / WHAT STAYS WITH YOU

What stays with you

Your AI builds on a private test version of your app and never sees your secret keys. Anything that changes your live app waits for your approval in your browser.

Add Gemmein to your AI. Then tell it what you want.

Building is free. No card until you go live.
