AI that fixes its own code, free
Too many AI app builders hand you broken code, then charge credits for every attempt to fix it. GenMB fixes errors while your app is generated, then tests your app in a real browser after every change. When it finds your app truly broken, fixing it is free, and GenMB only says fixed when a re-test is clean.
Fixed while it is built
Syntax errors, broken imports and common framework mistakes are caught and fixed during generation, before you see the app.
Tested after every change
GenMB loads your app in a real browser and flags it only when it is truly broken, confirmed by a second check. Minor console noise never raises a false alarm.
Free, verified fixes
One click on Fix now, up to 2 tries per error, at no credit cost. You see what changed, get a version you can undo, and a re-test before it says fixed.

Frequently asked
Do I pay credits when GenMB fixes errors?
Not for breakage GenMB finds. When a check confirms your app is truly broken (the page does not load, it is blank, a file will not compile, or it shows the crash screen), fixing it is free: one click on Fix now, up to 2 tries per error. If a freshly generated app shows an error, the first automatic fix attempt is free too. New features and changes you ask for in chat use credits as usual.
Will GenMB change my app without asking?
No. Code Healer works while your app is being generated, and if a freshly generated app shows an error, GenMB makes one free fix attempt you can follow in the chat. After that, GenMB never edits your app behind your back: it tests your app after every change and, if it finds real breakage, shows a Fix now button. Nothing changes until you click it.
How do I know a fix actually worked?
The chat shows exactly what GenMB changed and saves a version you can undo. GenMB then re-tests your app and only says fixed when the check is clean. If two tries do not solve it, GenMB offers to restore your last working version.
What kinds of errors does it fix?
Syntax errors, broken imports, and common framework mistakes during generation. After that, the free fix covers breakage GenMB confirms in your app: a page that does not load, a blank page, a file that will not compile, or the crash screen.
