Frequently Asked Questions
What is Sleek?
Sleek is an AI mobile app designer. Describe your app idea or attach a reference image, and the AI generates iOS and Android designs you can edit and export to Figma or code.

How does AI mobile app design work?
Describe your app idea in plain language, or upload a reference image. Sleek's AI generates complete mobile screens, including layout, components, copy, and styling. You can edit any of it visually and export when you're ready.
Is Sleek free to use?
Yes. The free plan includes 60 one-time credits, 1 project, and 3 screens. Figma and code export are included. Paid plans add more projects, monthly credits, and team features.
Can I export Sleek designs to Figma or code?
Yes. Every plan includes one-click export to Figma, where designs paste in as native, editable layers (no plugin required). You can also export to HTML or React with Tailwind CSS.
Can I use Sleek with AI coding agents like Claude Code, Codex, or Cursor?
Yes, with any of them. Sleek has an API, and its agent skill is a set of instructions that teaches an AI agent how to use it. So Claude Code, Codex, Cursor, or any other agent can drive Sleek directly: it creates a project, generates the mobile screens from your prompt, and pulls the result back as Figma layers or React code.
Do I need design experience to use Sleek?
No. Sleek is built for founders, product managers, marketers, and developers who need mobile app designs without spending hours in Figma. Describe what you want, and the AI handles the layout, hierarchy, and styling.
Can designers use Sleek to speed up their workflow?
Yes. Designers use Sleek to skip the early exploration phase and start with a high-fidelity design. Exported screens land in Figma as native, editable layers, so you can refine or restyle without losing work. Sleek doesn't replace Figma; it gets you a fast first draft you can build on.
What kinds of apps can I design with Sleek?
Any mobile app concept: fintech, social, e-commerce, productivity, wellness, AI tools, and more. Browse the templates library to start from an existing layout, or generate something custom from a single prompt.
Why use Sleek instead of a generic AI design tool?
Sleek is built specifically for mobile app design, not a general-purpose AI UI generator that also covers mobile. Every layout, component, and interaction pattern follows mobile conventions: iOS Human Interface Guidelines, Material Design, native navigation, accurate device dimensions, and tap-target sizing. The result looks like a real app instead of a website cropped to phone width.
How is Sleek different from Figma?
Figma is a manual design tool. Sleek generates complete app screens for you, then lets you refine them visually. You own the output and can move it to Figma or your codebase anytime.
