Sleek: AI-Powered Mobile App Design Tool

LinkTool

Sleek creates full iOS and Android app screens from text prompts or reference images. Designs can be exported directly as editable layers into Figma or as code in HTML and React with Tailwind CSS. The tool also integrates with AI coding agents like Claude Code and Cursor via an API.

Key points

  1. Specialised in mobile interfaces following iOS Human Interface Guidelines and Material Design conventions, including native navigation and tap targets.
  2. Generates complete screens from prompts or templates, covering layouts, components, styling, and copy.
  3. Export features include native editable Figma layers without requiring plugins, as well as HTML or React with Tailwind CSS.
  4. API and agent skills allow coding tools like Claude Code, Cursor, or Codex to trigger design generation directly within development workflows.
  5. Freemium pricing model offering one free project with limited AI credits alongside paid tiers.

Why it matters

Sleek reduces the friction of producing high-fidelity mobile prototypes for founders and developers without dedicated design teams. Enabling AI coding agents to drive design generation bridges the gap between interface concept and code implementation.

Analysis

Rather than attempting to displace manual editors like Figma, Sleek acts as a rapid first-draft engine. Its adherence to mobile-first UI standards prevents the common pitfall of AI-generated designs resembling desktop layouts scaled down to mobile viewports.
