Google introduced a feature within its Gemini platform, announced on November 5, 2026, that allows users to transform hand-drawn sketches into functional applications using the Canvas tool, a workspace launched in March 2025. Users can upload a photograph of a sketch to Canvas and prompt Gemini with "Can you code this app?", after which Gemini interprets the visual input and writes the corresponding code; the platform provides a preview window where users can test the generated application and make real-time adjustments to elements such as colors, fonts, and features. The workflow builds on Gemini's existing capabilities, including generating HTML/React web-app prototypes and Python scripts, and the Canvas tool was enhanced with Gemini 2.5 models in May 2025. For applications requiring persistent storage, Gemini automatically creates a Firestore database instance, though users can opt for alternative storage solutions; Google's documentation notes that Canvas apps are shared via public links, meaning anyone with access to the link can view and edit shared data, making privacy review a critical step before sharing prototypes containing sensitive information. Google has also documented a related sketch-to-code approach in its "Draw a Website" developer codelab, which involves uploading hand-drawn wireframes and optional text instructions that Gemini uses to generate website code through a Python Flask application deployed on Cloud Run.
