About

Built for the developers who ship alone.

Nuvex is an AI App Store and Google Play screenshot generator. It exists because every indie developer hits the same wall at launch: the app is ready, the listing is not, and neither budget nor time exists for a designer.

Why Nuvex exists

Most App Store screenshot tools are template libraries. You pick a layout from a finite menu, drop your app screens into labeled slots, and ship. The result is recognizable — and that is the problem. Users scrolling the App Store have seen these exact layouts before. The generic ones blend together. The distinctive ones cost $500 from a freelancer and take a week.

Nuvex started from one observation: you do not want a template. You want the output of having a designer — a set of frames that feel considered, specific to your app, and not obviously made by the same generator as the next app in search results.

"Every generated frame is a fresh composition — background, palette, type, copy, layout — picked for your app, not your template."

The design philosophy

Three rules shape every Nuvex generation:

  1. No two apps should look alike. The AI picks a palette, composition, and typographic system specifically for your app's category, tone, and one-line description. Nothing is reused between users.
  2. Refinement is cheaper than re-generation. If one frame out of five is wrong, you shouldn't lose the four that worked. Per-frame regeneration is a first-class feature, not a bolt-on.
  3. Copy matters as much as layout. Headlines are not blank slots. The AI writes them for your specific app, in language that turns a one-line description into a five-frame narrative.
