Google Stitch AI-Native UI Design Canvas
Announced by Google Labs on 18 March 2026 and described by Google as Stitch evolving into an AI-native software design canvas that lets anyone create, iterate and collaborate on high-fidelity UI from natural language: adding an AI-native infinite canvas, a design agent and Agent manager, DESIGN.md design systems, voice design with real-time critiques, and exports to AI Studio and Antigravity
Tool Overview
Features, steps and FAQ below
Features
- ✓ AI-native infinite canvas: Google says Stitch is now built around a new AI-native infinite canvas that gives ideas room to grow from early ideation to working prototypes, and lets you bring images, text or even code onto the canvas as context
- ✓ Design agent and Agent manager: Google says the new design agent can reason across the entire project's evolution, while the Agent manager tracks progress and helps you work on multiple ideas in parallel while staying organised
- ✓ Design systems with DESIGN.md: Google says you can easily extract a design system from any URL, or use DESIGN.md — an agent-friendly markdown file — to export or import your design rules to and from other design and coding tools
- ✓ Instant interactive prototypes: Google says you can stitch screens together in seconds and click Play to preview an interactive app flow, with Stitch automatically generating logical next screens based on the click
- ✓ Voice design and developer handoff: Google says you can speak directly to your canvas for real-time design critiques and updates (like 'give me three different menu options'), and bridge to AI Studio and Antigravity through an MCP server, SDK and skills
