Stitch by Google
Stitch is Google’s AI-powered interface generation tool designed to turn rough ideas into editable UI designs and production-ready code within seconds.
The product is aimed at founders, PMs, and builders who want to move from concept to working interface faster without spending days on mockups, handoffs, or repetitive UI iteration.
Instead of starting in a traditional design tool, users can describe an interface idea in natural language or begin from rough sketches, and Stitch generates both the visual design and implementation layer together.
More than static mockups
One of the more interesting parts of Stitch is that the output isn’t treated as a dead-end image or prototype.
Generated interfaces remain editable, and the platform is designed around bridging the gap between:
- early product ideation
- UI design exploration
- real implementation workflows
The system also introduces “Hatter,” an AI agent focused on handling more complex multi-step design tasks rather than single-shot generations.
What the platform includes
- Prompt-based UI generation
- Editable interface layouts
- Production-oriented code output
- Multi-step AI design agents
- App Store asset generation
- MCP export support
Where it fits
A lot of modern AI design tools either stop at visual inspiration or focus purely on code generation. Stitch sits somewhere in between by trying to connect product thinking, interface design, and implementation into one continuous workflow.
For small teams especially, that can significantly reduce the time spent bouncing between whiteboards, mockups, prototypes, and frontend implementation before an idea becomes something usable.
