Google expands the Canvas tool in Gemini with code generation from photos of sketches
Google has added a feature to the Canvas tool in its Gemini product that automatically generates working code from a photographed sketch of an app. The result can be tested and edited immediately in preview.
Google has announced a new feature for the Canvas tool in its Gemini product that allows users to upload a photo of a hand-drawn sketch — for example, an app design, a habit tracker, or a game board — and ask the Gemini model to generate working code based on it. The model analyzes the visual input and writes the corresponding app code itself.
According to the company, the resulting tool can be tested immediately in a preview window and edited in real time, including changes to colors, fonts, or functionality. Google's stated goal is to simplify app prototyping — an idea sketched on paper can thus be quickly turned into an interactive web app.
The source material is a short promotional description of the feature and does not contain further technical details, such as availability in individual regions, pricing, or limitations on the type and complexity of sketches that can be processed. See the source article for details.
Why it matters
The feature lowers the barrier between an idea and a working prototype — no programming skills or interface design tools are needed, just a sketch on paper. This can speed up early-stage product development as well as personal experimentation with simple apps.
Two audiences, two different impacts
What this means
For individuals
Anyone who first sketches an idea for a simple app or tool on paper can quickly try it out as a working prototype using Gemini Canvas, without writing any code.
For a business
Companies developing products or internal tools can shorten the rapid prototyping phase — ideas from workshops and design meetings can be turned into a testable form without involving developers.
