Overview

Sleek is an AI-powered tool that facilitates the design of mobile applications for both iOS and Android platforms. This tool is designed for a variety of users, from founders and product managers to developers and marketers, looking to create mobile app designs with no specialized design experience.

Users simply describe their app idea or attach a reference image and Sleek's AI generates the design, including the layout, components, copy, and styling.

The generated designs are completely editable, allowing for quick iterations and refinements to build an interface that best suits the user's needs. Sleek supports the exportation of designs to Figma or directly to code for further usage.

Besides creating unique app designs, users also have the option to choose from a library of hand-picked app design templates. Sleek also provides ways for users to collaborate with AI coding agents like Claude Code, Codex, or Cursor, and its functionalities can be utilized to speed up designers' workflow, without replacing design tools like Figma.

While it can generate app designs across a broad spectrum of concepts, including fintech, social, e-commerce, productivity, wellness, and AI tools to name a few, its main distinction is its specificity for mobile app design, with adherence to iOS Human Interface Guidelines and Material Design conventions.
