AI app builder

Describe the app. Get working software.

Not a prototype and not a mockup — apps that take input and save it, with the database included and the code in a repository you own.

A working calculator cost $0.0072 to build, measured.

In short

One sentence becomes a working app: forms that save, calculators that compute, bookings that land in a database you can read from your dashboard. Real examples below, priced.

See it work

The app: a message asking for a barbershop booking site, Amelia's plan in reply, and the price of the turn shown under the composer.

Describe the app, approve the plan, watch it build — the database is already there when the first form saves.

The model picker: keep costs down, balanced, best result — with the price shown against each model.

300+ models, each with its price on it.

The account page: usage included in the plan, and a spending limit nothing can pass.

A spending limit, on from day one.

Working, not pretend

The demo apps actually run.

Booking systems

Take a booking, save it, read it back from your dashboard. Built from one sentence, no scheduling subscription attached.

Quote calculators

Real arithmetic, checked as part of the build — a calculator that is nearly right is worse than none.

Games with saved scores

Playable right now, with a shared leaderboard backed by the included database. Tap one and play it.

Real output, not mockups

The part builders skip

The app is yours.

Every build lives in a plain git repository from the first turn — yours to clone. Run it on our machines, on your own computer, or hand the repo to any developer — nothing about it is specific to us. An app that only exists inside a builder is an app you rent; see what that usually costs.

Working software from a sentence — the first version is free to try.

Questions

Asked, answered

Can AI really build a working app?

Yes — the booking systems and calculators in our showcase take real input and save it to a real database. They were each built from a one-sentence description, and the screenshots are the untouched output.

Does it include a database?

Yes. Anything that needs to save — bookings, form entries, orders, scores — writes to a database that comes with your account. No Supabase to wire up, no separate host to pay.

What does it cost compared to app builders like Bubble or Glide?

Per-seat builders charge monthly whether you ship or not. Here you pay for the work as it happens — a working calculator cost $0.0072 to build in our measured runs — plus a plan from $10 a month billed annually.
