Quick answer
An AI app builder for startup founders
A founder shipping without an engineering team carries two risks at once: the app quietly not working, and the launch quietly not happening. Most AI builders address neither — they stop when the code exists.
PromptUI is built around the second half: every build is verified on the rendered app, deploys carry inspectable proof you can show a customer or investor, and the launch kit and Growth Agent turn the same product context into announcement and marketing drafts you approve.
- 1
Build or import
Start from a prompt, or import a repository your technical co-founder — human or AI — already produced.
- 2
Verify before you show anyone
Verification runs on the rendered app: what paints, what works, what a user actually meets. Findings come back for review, and fixes are plain-language prompts.
- 3
Deploy with proof attached
One click to a live URL, with a public proof page recording the checks the build passed — evidence, not assurances.
- 4
Launch and keep launching
The launch kit drafts your announcement; the Growth Agent keeps drafting posts and campaigns from your real product. Everything waits for your approval.
Bring your app to PromptUI
Import the repository, watch the verification run on the real rendered app, and go from repo to launched.

Common questions
- Do I need to know how to code?
- No. You describe what you want and review what you get — in the preview, not in the source. Your code remains exportable to GitHub or ZIP whenever you want it.
- What happens when something breaks after launch?
- Guardian watches deployed apps for runtime errors and surfaces repair signals, so problems become visible instead of silent.
