What sleek.design is
sleek.design is an AI-driven mobile app prototype generator. The problem it targets is familiar: someone has an app idea but no designer and no budget for one. You open the site, describe the concept in a chat with the AI or upload a reference image, and the platform produces app screens within minutes. From there you can edit and iterate, work from pre-made templates covering app types such as meditation, fitness, and expense tracking, or clone an existing design to move faster. Designs export as code or Figma files, and the service is free to start with paid packages from $23 to $69.99.
What you can do with it
- Generate app screens by chatting with the AI.
- Edit and iterate on the generated designs.
- Export designs as code or Figma files.
- Start from templates or clone an existing layout.
Who it is for
- Non-technical founders without design skills.
- Entrepreneurs testing app ideas and gathering feedback.
- Developers who want a visual starting point.
What to watch out for
Paid packages run from $23 to $69.99, so serious use means a subscription. The generated screens are a starting point, not a finished design system, and they still need cleanup for spacing, states, and edge cases. An export is not an app: turning the design into a working product is developer work. Check which export formats sit behind which plan before you commit. Behavior may vary across browsers and devices, so test before production use and consult the help docs if errors appear. Features and interface details may change between versions, so review the latest notes on the page before you start.
