Stitch

Turning a rough app idea into screens usually means opening a design tool and drawing every layout by hand.

Stitch skips that step.

It is a free AI UI design generator from Google that creates interfaces for mobile and web apps, using Gemini models from Google DeepMind.

You can adjust and iterate on a design after it is generated, then export static HTML code or a Figma file.

Designs you generate remain yours.

Access comes with conditions.

Stitch needs a personal Google Account, is open to users 18 and over in select countries and territories, and the site is English only.

Free use has monthly generation limits of 350 in Flash mode and 50 in Experimental mode, so heavy iteration can run into the cap.

Conversations imported from Galileo AI cannot be continued inside Stitch.

The exported code is static HTML, which suits it more to early ideation and handoff than to a finished production app.
