AI app builder · early access

Tell the AI what you want. It’s already live.

Describe your app in plain words and get a real, hosted, full-stack app — a website with a database, sign-ins, payments and emails, plus a native mobile app. Then keep changing it the same way you made it: by chatting.

Why it’s different

Not another code generator.

No code dump

Other AI builders hand you a project you still have to wire up, deploy and babysit. Here there is no deploy step — your app is born running, on its own address.

No demo backend

A pretty page isn’t a product. You get the real thing: a database, user accounts, Stripe payments, transactional email — built in and hosted.

No lock-in

Export your entire app as a standalone codebase any time — run it on your own server, publish it to the app stores under your own name. Your work stays yours.

How it works

From sentence to shipped in three steps.

1

Create a project

It’s online immediately at yourname.startupjs.ai — or connect your own domain, HTTPS included.

2

Say what you want

“A shop for my pottery studio.” Watch pages, design and data appear while you chat — the AI is your admin panel.

3

Keep going

Ask for changes forever — new pages, new features, new look. Scan a QR and it’s a native app on your phone.

What you get

A real product, not a prototype.

💬

The AI is your admin panel

Every change happens by asking — pages, components, design, data. Live immediately, no rebuild, no redeploy.

🗄️

Full stack, included

Database, user accounts with Google sign-in, Stripe payments on your own account, transactional emails. Real features, not mockups.

📱

Native mobile app, day one

Every project is also a native app — scan a QR code and open it on your phone. Publish to the app stores when you’re ready.

🌐

Your own domain

Point one DNS record at us and your app serves on your domain with automatic HTTPS. The free subdomain keeps working too.

📦

Bring your prototype

Made something in an AI design tool? Upload the zip — the AI reads it and rebuilds it as a working full-stack app, assets and all.

🧾

Honest AI pricing

AI usage is billed from your credit at provider cost with a transparent markup. You only pay for what you actually use.

No lock-in

Leave whenever you want. Really.

One click exports your entire project as a standalone app you own completely.

  • Everything comes with you — pages, components, data model, content, themes, plugin setup.
  • Self-host it on any server, or hand the archive to your own AI coding agent — setup instructions it can follow are inside.
  • Ship it to the app stores under your own name. It’s a complete codebase, not an API tether.
