Stitch is an AI-powered tool that generates user interfaces for mobile and web applications. Its main purpose is to make design ideation fast and easy by transforming simple descriptions or sketches into functional UI designs.

The product can turn napkin sketches into production-ready UI in seconds. It generates editable design files along with real code that can be used directly in development workflows. Stitch introduces Hatter, a new agent designed to handle multi-step design tasks efficiently.

Stitch provides new App Store asset generation capabilities, allowing users to create all necessary assets for app store submissions. It also features native MCP (Model Context Protocol) export functionality for seamless integration with development pipelines.

The tool works by taking user descriptions or sketches and using AI to generate complete UI designs with corresponding code. This approach eliminates the need for manual design work and accelerates the prototyping process significantly.

Stitch benefits founders and product managers who need to create mockups quickly without wasting weeks on design iterations. It's particularly useful for rapid prototyping and getting from idea to implementation faster.

The target users are founders and product managers who need to create UI mockups efficiently. The tool integrates with development workflows through its code export capabilities and supports both mobile and web application design.
