Overview
Stitch, formerly known as Galileo AI, is an AI-powered design tool that was acquired by Google. Announced in its new form on May 20, 2025, Stitch generates user interface designs and corresponding front-end code (HTML/CSS) from natural language prompts and image inputs. It leverages Google's advanced Gemini models and builds upon Galileo AI's original mission to make design easy and accessible, offering similar capabilities with enhanced Google AI integration.
Key Features
✦ Text-to-UI Generation: Creates UI designs from plain English descriptions.
✦ Image-to-UI Generation: Converts sketches, wireframes, or existing UI screenshots into editable digital designs.
✦ Powered by Google's Gemini Models: Utilizes cutting-edge AI for advanced design and code generation.
✦ Rapid Iteration & Variants: Allows users to generate multiple design options and refine them conversationally.
✦ Figma Integration: Designs can be directly pasted into Figma for further refinement and collaboration.
✦ Front-End Code Export: Generates clean HTML and CSS code from the created UI designs.
✦ Evolution of Galileo AI: Continues and expands on the vision and capabilities of the original Galileo AI platform.
Advantages
🟩 Accelerated Design Workflow: Significantly speeds up the process from idea to initial design and code.
🟩 Enhanced by Google AI: Benefits from the power and continuous development of Google's Gemini models.
🟩 Accessible Design: Lowers the barrier to entry for UI design, empowering non-designers.
🟩 Design-to-Code Bridge: Smoothly transitions visual designs into functional front-end code.
🟩 Continuity for Galileo AI Users: Offers a path forward for users of the original Galileo AI, with data migration options.
Limitations
🟥 Experimental Tool: As a Google experiment, features and stability may evolve.
🟥 Not a Full IDE/Design Suite: Focused on initial UI generation and iteration, not a replacement for comprehensive design or development environments.
🟥 Prompt Engineering: Achieving precise results may depend on the clarity and detail of user prompts.
🟥 Migration Deadline: Existing Galileo AI users need to migrate data to Stitch by June 20, 2025.
Use Cases
➤ Rapid UI/UX Prototyping: Quickly creating interactive mockups for web and mobile applications.
➤ Conceptual Design Exploration: Generating diverse UI options from initial ideas or visual references.
➤ Streamlining Developer Handoff: Providing developers with a starting point for front-end code.
➤ Quick Ideation for Startups: Enabling fast visualization of product UIs for MVPs.
Pricing Details
⭘ Free to Use: Stitch is currently offered as a free experimental tool by Google.
⭘ Data Migration: Existing Galileo AI users have until June 20, 2025, to migrate their data to Stitch.
Summary
Stitch, formerly Galileo AI and now part of Google, is a free AI tool that generates UI designs and front-end code from text or image inputs using Google's Gemini models. It continues Galileo AI's mission to simplify design, offering rapid prototyping and Figma integration.
Released Dates
2025
Jan – The research paper detailing the Stitch model and its "Stitched-n-Context-Tuning" (SNiC) method was published, showcasing its capabilities in handling very long context windows.
2024
The Stitch model was developed within Google Research as a project to overcome limitations of standard long-context models.
