Read Google Stitch 2026 Review >

What is Galileo AI?

Galileo AI is an AI UI design tool that transforms written prompts and rough sketches into editable, hi-fi wireframes for web or mobile apps. It focuses on accelerating early-stage product design and simplifying developer handoff through quick code and Figma exports. 

Galileo AI is Now Google Stitch

In mid-2025, Galileo AI was acquired by Google and relaunched as Google Stitch, an AI app builder powered by Gemini. Stitch expands Galileo AI’s text-to-UI capabilities, Figma design generations, and production-ready HTML/Tailwind code from simple prompts.

Galileo AI UI Design Features

Text-to-UI design

Generate and modify UI designs simply by describing them in text form. The prompt can contain a detailed explanation of the screen, like a PRD, or can be something simple describing user needs.

Sketch to design

Galileo also supports image prompts, allowing you to upload images of wireframes or sketches to convert them into high-fidelity designs.

Style Editing

You have control over the basic visual style of the generated screen. Galileo allows you to change fonts, accent colors, and border-radius.

Figma Export

Directly export UI screens into Figma. This allows designers to refine layouts, adjust auto-layout settings, and maintain design system consistency.

Code Export

Galileo AI UI tool doubles up as a design-to-code tool, allowing seamless developer handoff. You can also open the design as code in Replit or other AI coding agents.

Galileo AI Use Cases

Small teams and startups

Galileo AI’s user-friendly interface makes it ideal for small teams looking to develop UI prototypes quickly without a dedicated design team.

For non-designers

It's accessible to non-designers such as product managers and marketers who may need to create visual mockups for pitches or presentations.

For professional designers

Seasoned designers can use it to be faster and explore more concepts within a short time period. Design-to-code export features make it well-suited for larger projects and client-facing deliverables.

Verdict: Is Galileo AI Worth it?

Galileo AI proved that text-to-UI generation could dramatically speed up early product design. Since its acquisition by Google and transition into Stitch, its core capabilities live on in a more powerful Gemini ecosystem. However, its original free plan was limited. 

If you’re exploring 2026 Galileo AI alternatives, tools like Banani offer a practical starting point for prompt-based UI design.
