How to Build a Chat App With AI

Build a working chat app for iOS, Android, Web and macOS in minutes — no setup, no SDKs, no boilerplate. Just describe what you want.

What you will build

A real native chat app for real-time messaging for a community or product, with the following features:

Step-by-step

Step 1: Open Luna at luna-heaven.web.app

No signup wall — you can start in seconds. Luna will greet you. Tell her what you want to build.

Step 2: Describe your chat app in plain English

Tell Luna: "I want a chat app for real-time messaging for a community or product. The core features I need are real-time messaging, rooms, media." Luna will ask clarifying questions.

Step 3: Watch Heaven Code Studio generate Flutter code

Luna writes real, owned Flutter code — not pseudocode — across screens, services, models and theming, with deterministic spec fallback so the preview always renders.

Step 4: Preview your app live in the browser

Heaven Code Studio renders your app live. Tap, scroll, navigate — give Luna feedback by voice or text and she iterates.

Step 5: Deploy to iOS, Android, Web and macOS

Export the Flutter project, run flutter build, and deploy. Or use Luna's guided deploy assistance to ship to the App Store / Play Store / Firebase Hosting.

Frequently asked

Can Luna really generate a working chat app?

Yes. Heaven Code Studio writes real Flutter code that runs on iOS, Android, Web and macOS. The output is yours — exportable as a normal Flutter project — and Luna will iterate with you across sessions thanks to persistent project memory.

Do I need to know how to code?

No. You describe what you want; Luna writes the code. If you do know how to code, Luna becomes a faster pair — you can edit any file directly and she will continue from your edits.

Is this free?

Yes. Luna is free forever; Heaven Code Studio is included. An optional Chip subscription unlocks priority routing and more concurrent companions.

Where does my code live?

Your project lives in your Memory Pod (encrypted, cross-device). When you are ready, you export a normal Flutter project to your own GitHub / hard drive.

Can I ship to the App Store?

Yes. The output is a standard Flutter project — you can sign and submit it through Xcode like any other app. Luna can also guide you through the App Store / Play Store submission process.
