Galileo AI was a generative AI platform for UI design that created high-fidelity, editable interface mockups from natural language prompts. Co-founded by Arnaud Shen and Helen Zhou, the product let product teams and designers describe a screen or flow in plain English and receive pixel-perfect Figma-ready designs complete with realistic content, components, and layouts. Galileo AI's core innovation was treating UI generation as a content-aware problem rather than a pure image synthesis task — the outputs included real text, functional components, and design-system-friendly structures that designers could refine rather than discard.
The platform offered a popular Figma plugin alongside its web-based interface, letting designers generate screens directly inside their existing design workflow and iterate on outputs without leaving the canvas. Common use cases included exploring multiple design directions before committing to detailed implementation, generating starter mockups for client presentations, and accelerating early-stage product discovery with rapid visual prototyping. Galileo AI was widely recognized as one of the most visually polished AI UI generators during its standalone run from 2023 to 2025.
In May 2025, Galileo AI was acquired by Google and relaunched under the Google Labs umbrella as Google Stitch, an AI app builder powered by the Gemini model family. Galileo AI no longer operates as an independent product — the original usegalileo.ai site now redirects users to Stitch, and former users can import their conversation history into Stitch through settings, though imported chats are view-only. The core generation engine that made Galileo popular now runs on Gemini and benefits from Google's infrastructure, with smoother integrations for Figma export and front-end code generation.
