Gemini Canvas turns paper sketches into interactive apps

What is changing?

Google has published a new Gemini Canvas workflow that turns an idea on paper into an interactive app. A user uploads a photo of a sketch—such as an app mock-up, habit tracker, or game board—selects Canvas, and asks Gemini to code it. Gemini reads the visual structure, writes the code, and produces a preview.

The prototype can be tested in Canvas’s preview window, while colors, fonts, and features can be refined conversationally. The announcement does not introduce a new model version or promise automatic app-store deployment; it focuses on moving from a visual draft to a working first prototype through chat-based iteration.
