The design canvas built for AI coding agents
Generate complete, multi-screen interfaces from a text prompt, PRD, screenshot or pasted product URL rather than a single static screen.
Every design maps directly to code, so you can preview interactive prototypes quickly or export and ship the implementation.
Iterate by asking the AI for changes, or click any element and edit it by hand — the two modes work on the same file.
Connect Cursor, Claude Code, Windsurf or Codex so agents can generate screens and edit designs inside your editor.
AI mobile app designer that turns a prompt into every screen
Describe your app and Sleek generates the full set of mobile screens in one matching style, covering layout, components, copy and styling.
Layouts follow iOS Human Interface Guidelines and Material Design, with accurate device dimensions and tap-target sizing instead of desktop UI shrunk to a phone.
Screens paste into Figma as native editable layers without a plugin, and export as React with Tailwind CSS or plain HTML on every plan.
An API and agent skill let Claude Code, Codex, Cursor or any coding agent create a project, generate screens and pull results back as Figma layers or code.
