Google Stitch
Google's free Gemini-powered UI generator (formerly Galileo AI).
Acquired — still operating
formerly Galileo AI; acquired by Google May 2025
About
Google Stitch (stitch.withgoogle.com) is Google's free UI generator: prompt (or voice) to app UI designs with an infinite canvas, powered by Gemini.
History matters here: this was Galileo AI, the text-to-UI startup Google acquired in May 2025. Note: the galileo.ai domain now belongs to a DIFFERENT company (an AI eval/observability platform, already in this catalog as 'galileo') — don't confuse them.
