A free AI app builder
that runs in your browser
Describe the app you want. GenSiteHub generates it, lets you preview it, and helps you prepare it for Android — without leaving your browser.
What is GenSiteHub?
GenSiteHub is a free, browser-based AI app builder. It lets you describe an app in plain language, generate a complete single-file HTML application using your own AI model via OpenRouter, preview it instantly, and prepare it for Android packaging — all without leaving your browser.
No sign-up is required. No data is sent to our servers. Your API key and generated apps stay in your browser's localStorage only.
Who is it for?
GenSiteHub is designed for:
- Developers who want to prototype app ideas quickly
- Non-technical users who want to create simple utility apps without writing code
- Students and learners exploring AI-assisted app development
- Makers who want a lightweight tool to build personal productivity apps
What it is not
GenSiteHub is not:
- A full native app development platform
- A replacement for Android Studio or Xcode
- Suitable for complex apps requiring a backend, real-time data, or native hardware APIs
- Guaranteed to produce Play Store-ready apps
Generated apps are HTML-based and run inside a WebView when packaged for Android. They are best suited for lightweight tools, utility apps, calculators, trackers, and similar single-purpose applications.
