how the build works

Six stages. One line in,
a running app out.

The pipeline plays itself below. Estimates, never promises: about two hours in total. The bars move at an honest pace, weighted by the minutes each stage really takes.

Stage 1 business thinking stays private. It never appears on screen, in files, in the film or in any marketing. You watch progress. You receive the prototype, the UX files and the build spec. The thinking is the machine's.

what you get

One build. Everything
in your hands.

who it is for

Four people walk in.
Each leaves with something real.

01

Solo dreamer

Working full time or recently laid off. Wants to see the idea real without learning to code or wrestling AI tools for weeks.

Type one line and get something real to show people.

02

Vibe coder

Already uses Lovable, Cursor or Replit. Wants a high-quality starting point without burning hundreds of credits getting there.

Save days and a pile of credits on the first mile.

03

Agency or freelancer

Pitches for a living. Wants fast, cheap, impressive client demos, in volume.

Pitch with a working app, not a mock-up.

04

Idea buyer

Would rather acquire than build. Wants a finished app plus a premium domain, ready to run with.

Buy a running start, not a plan.

price

Simple money. One price.
Spent only on success.

common questions

Asked before you ask.

Do I need to know how to code or prompt?+

No. The Idea Computer asks for an idea name and a short description. That is all. There is no chat, no prompting and no back-and-forth with an AI anywhere on the site. If you can write two sentences, you can run a build.

What exactly do I get?+

A hosted demo (free for 7 days), the full app source files, the UX and brand files, a technical build spec ready for Cursor, Lovable, Claude Code or a developer, and a next-step prompt for the road to production. Everything arrives in one email. You own all of it from day one.

What if the build fails?+

The screen says BUILD STOPPED., gives the reason, and your 69 credits are returned automatically. No tickets, no asking. RETRY starts again with the same idea, NEW starts a fresh one.

How long does it take?+

About two hours, across six stages. The build runs on our servers whether or not your browser is open, so you can close the tab and live your life. We email you when it is done.

Is my idea private?+

Your ideas are private. They are never listed, sold or shown to anyone. The business thinking the pipeline does internally is never shown, sold or downloadable. There are no third-party trackers on this site.

What happens after the 7 days?+

The demo URL shows "this demo has ended" and your files stay downloadable. Premium hosting costs 10 credits and keeps the demo live for 365 days with the footer credit removed. You get reminders 2 days before and on expiry.
