What Gemmein adds to your app
An AI builder gets you a working interface fast. It does not set up what sits behind it: who a person is, what they can see, how they pay, and how an AI feature runs without exposing your provider key. Gemmein provides that part.
Four things to add
Sign-in
People sign in with a one-time sign-in code sent by email. There are no passwords in the system. How passwordless auth works.
Protected data
Records live in collections, and each collection has one of eight server-enforced safety rules, so one person can never read another's records.
Payments and access
Stripe is built in, any provider that signs its webhooks to a supported standard connects through a relay, and App Store and Play purchases arrive through RevenueCat. The money goes to your own account. Access and credits are granted when the signed payment webhook arrives; the checkout redirect grants nothing.
Server-side AI
Your provider key stays on the server, and your app calls named AI tools priced in credits. Where your key should live.
Check the fit, then build
Before you install anything, have your agent read the guide and check whether Gemmein fits. The guide opens with a checklist that maps your app's needs against what Gemmein supports, and your agent gives you a verdict. Building is free: on your computer against a local backend, or in Development through the Gemmein connector. You add a card only when you go live.
What Gemmein does not include
Sign-in is by sign-in code only. Social sign-in, team roles and SSO are not part of Gemmein. If something is not described in the docs, it is not built. Plan around these limits before you build.
Frequently asked questions
Do I have to rebuild my app?
No. You keep the front end you built, and your AI connects it. Gemmein can host it for you, or it stays where it runs now.
Which builders does this work with?
Any web front end, including apps started in Lovable, Bolt, Base44 or v0, through one JavaScript and TypeScript SDK. On mobile, Expo and React Native apps use the SDK's Expo entry and Apple apps use the Swift package.
