Describe an app.
Get a working one.
App Builder turns a plain description into a working web app with pages, forms, lists and summary cards. Every revision is saved and encrypted in your workspace. Preview it on desktop and phone, run browser tests, export the source, publish a link, and take the same app to Android as a native Kotlin project. AI generation runs on your own provider account; a release costs $2 for web and $5 for Android, only when it succeeds.
Your applications
Build a web app. Keep its history. Take it to Android.
A small tool can make a big difference.
Start with a task tracker, inventory, or a page for your work. Describe the changes you want as you go.
What should we change?
Describe pages, forms, lists, or summary cards. Records are saved locally; shared accounts and backend services are outside this first release.
AI generation requires your own AI API account connected in AI Hub. Your provider bills model usage; ASL charges the release build fee. Source export is included with a successful paid release build.
Preview records are temporary. Publishing keeps a separate version until you choose to publish again.
Saved revisions
Restore a revision as a new saved version. Existing history is retained, up to the latest 30 revisions.
Checks you can inspect
Browser tests open the actual generated app, exercise its forms and navigation, check mobile layout, and verify local record persistence.
Published version
Your app, in your hands
Export a self-contained website ZIP or edit the application definition. Preserve collection and field IDs to keep existing records usable.
Unpublish and finish active jobs first. Deletion removes the saved app and packages; retained backups age out separately.
Take your app to Android.
Use the same pages and collections in a native app. Export the Android Studio project or build unsigned release APK and AAB packages for your own signing process.
Before Google Play
An unsigned package is ready for your signing step, not for submission. Sign the AAB with your upload key and configure Play App Signing. Test the signed app, prepare your listing, screenshots, privacy policy, Data safety and content rating, and complete any account-specific testing requirements.
Your signing keys stay with you. This builder targets Android API 36 and does not request network or sensitive permissions.
