Gemini Canvas changes what Gemini is for. Without Canvas, Gemini is a chatbot – you type a question, you get text. With Canvas, Gemini becomes a creation tool. You describe what you want, and Gemini builds it: a working web page, an interactive quiz, flashcards with flip animations, an infographic in HTML and SVG. The output is not text describing the thing. The output is the thing itself.

TL;DR – Canvas quick reference

Six templates: Web page, Infographic, Quiz, Flashcards, Audio overview, Custom app
How to trigger: type “use Canvas to…” in any conversation, or tap the Canvas icon in the compose bar
Live preview: desktop renders output in a resizable side panel; iterate by continuing the chat
Iterative editing: “change the blue to #2563EB,” “add a fourth flashcard,” “make the hero larger” – each prompt updates the running preview
Export: download self-contained HTML, copy source, screenshot, or save as Markdown where applicable
Sandboxed: output runs in an isolated iframe – no access to your data, cookies, or files
Desktop vs mobile: desktop shows chat + preview side by side; mobile toggles between the two
Closest comparisons: Claude Artifacts (React in a sandbox, developer-focused) and ChatGPT Canvas (document editing, lighter on generation)

Windows users: the official Google app for desktop on Windows (released April 14, 2026) is not a Gemini chat client and does not expose Canvas – it is an Alt+Space search launcher with a 20 MB file limit and no Canvas panel. For Canvas on Windows you either open gemini.google.com in a browser or use a native client like GeminiDesktop.app. See Google didn’t make a Gemini Windows app for the full context and native Gemini Windows app alternatives for workable Windows setups.

The six Canvas templates

Web page

Generate complete, styled HTML pages from a text description – portfolios, landing pages, resumes, event invitations. The output is a self-contained HTML file, responsive by default. The real value is iteration: after generation, ask Gemini to change the color scheme, rearrange sections, add a contact form. Each change happens in the live preview without starting over.

A typical workflow: start with “build a one-page portfolio for a freelance illustrator, with a hero, a grid of six recent works, and a contact form.” Gemini produces the first pass. Then iterate: “swap the serif header for a rounded sans,” “make the hero 80vh instead of full-viewport,” “move the contact form above the grid.” Each revision is a turn in the conversation, and each turn updates the same HTML document rather than regenerating from scratch.

Infographic

Generate visual data presentations using HTML and inline SVG – statistics, timelines, process flows. Unlike flat PNG generators, Canvas infographics are live HTML: text is selectable, SVG scales to any resolution, and you can modify data points or restructure the layout through conversation. Not a D3 replacement, but for quick presentation or blog graphics, it produces usable output in seconds.

The practical ceiling: Canvas infographics are best for 5-15 data points and two or three visual hierarchies. Past that, iteration becomes slow because the model rewrites the entire SVG tree on each change. For dense dashboards, hand off to a real charting library.

Quiz

Generate interactive multiple-choice assessments with scoring. Provide a topic or paste source material, and Gemini creates questions, answer tracking, and a score summary. The quizzes render as interactive HTML with immediate feedback on each answer. Useful for educators, trainers, and anyone turning text into self-assessment.

Flashcards

Create study cards with CSS-based flip animations. Provide terms and definitions, and Gemini generates a deck that flips from front to back on click, with navigation and shuffle support. Beyond education – also useful for onboarding materials and product feature summaries.

Audio overview

Generate a spoken summary of content you provide. Paste a document or meeting notes, and Gemini creates a condensed text summary then runs it through TTS to produce audio. Listen while commuting or exercising. Similar to NotebookLM audio summaries, but integrated directly into the Gemini conversation flow without switching products.

Custom app

The most open-ended mode. Describe an interactive application – calculators, converters, timers, simple games, form builders – and Gemini builds it in HTML, CSS, and JavaScript. This template reveals what Canvas really is: a code generation engine with a live preview renderer. The other five templates are specializations of this same capability.

Canvas vs Artifacts vs ChatGPT Canvas – a side-by-side

These three creation surfaces are often lumped together, but they target different problems. Here is how they actually differ when you sit down to build something:

Feature	Gemini Canvas	Claude Artifacts	ChatGPT Canvas
Primary format	HTML + inline SVG + JS	React components in sandboxed iframe	Document surface (text / code)
Template presets	6 built-in (web page, infographic, quiz, flashcards, audio, custom app)	None – freeform	None – document + code
Live preview	Side panel on desktop	Side panel on desktop	Side panel on desktop
Iterative editing	Natural-language turns	Natural-language turns	In-document highlight + edit
Audio generation	Yes (TTS built-in)	No	No (requires separate voice mode)
Best for	Polished deliverables	Developer prototypes, data viz	Long-form writing + light code
Weakness	Template-driven guardrails limit advanced cases	Requires React literacy	Weaker on generating interactive UIs

Claude Artifacts renders React components in a sandboxed iframe. It supports HTML, JavaScript, SVG, and Mermaid diagrams. Artifacts excels at developer-oriented use cases – prototyping components, building data visualizers. The React foundation gives more structural power for complex applications but means the output is not always a simple portable HTML file.

ChatGPT Canvas is primarily a document editing surface. It opens a side panel for collaborative text and code editing – highlighting sections, requesting rewrites, adjusting tone. Strong as a writing tool, weaker for generating interactive deliverables like quizzes or flashcards.

Gemini Canvas occupies a middle ground. More template-driven than Artifacts, which makes it accessible to non-technical users but less flexible for advanced cases. More creation-oriented than ChatGPT Canvas, better for producing deliverables but less useful as an editing collaborator. The six-template structure guides users toward polished output types but sends anything outside those templates to the more capable but less guided custom app mode.

Canvas on the desktop

Side panel with live preview

On desktop, Canvas renders in a side panel alongside the conversation. Chat on one side, live preview on the other. Changes happen in real time as you iterate – no tab switching, no waiting for a separate window. This is where desktop screen space pays off. On mobile, you toggle between conversation and preview. On a monitor, both are visible simultaneously.

Iframe sandboxing

Canvas output runs in a sandboxed iframe – generated HTML and JavaScript execute in isolation from the host application. No access to your data, cookies, or system resources. You can safely preview and interact with any Canvas output.

Desktop workflow integration

Canvas outputs fit into broader workflows on desktop. Download generated HTML and host it. Copy source code into your project. Screenshot an infographic for a presentation. Export flashcards for offline study. The desktop environment provides the file system, clipboard, and application ecosystem that make Canvas outputs actionable rather than ephemeral.

Step-by-step: your first Canvas output

Open Gemini for Mac (Option+Space for mini, Option+Shift+Space for full window).
In the compose bar, type a creation prompt: Use Canvas to build a one-page pricing comparison table for three plans (Free, Pro, Team) with monthly/annual toggle.
Press Cmd+Enter. The Canvas panel opens on the right.
Wait for the first render. Small outputs complete in 5-15 seconds; complex apps can take 30-60.
Iterate: Make the Pro card emphasized with a subtle shadow. Change monthly savings text to green.
Export: click the download icon above the preview. You will be offered HTML download, copy-source, or open-in-new-tab.
(Optional) Drag the downloaded HTML into any browser to verify it works standalone, with no Gemini runtime required.

If you do not see the Canvas panel after a Canvas prompt, the most common causes are (a) you clipped the word “Canvas” from your prompt – the current builds still parse this as a routing hint – and (b) your window is narrower than the minimum Canvas width (~900 px). Resize or maximize the Gemini window and try again.

Advanced tips and power-user tricks

1. Use Canvas to stage, then copy into your real tools

Canvas is not trying to replace Figma, Notion, or VS Code. It is trying to get you from idea to “something tangible to critique” faster. Treat Canvas output as a staging ground: generate the first version in Canvas, critique it with fresh eyes, then copy the parts that survive into your real editor. This is faster than scaffolding from a blank file.

2. Chain templates

Canvas templates can reference each other. Generate an infographic of a concept, then say “turn this infographic into a 10-question quiz” – Gemini reads the infographic and produces a matching quiz. Chain: article text -> audio overview -> infographic summary -> quiz for learners. Each step is one prompt.

3. Use “export as Markdown” for knowledge bases

For content-heavy Canvas outputs (infographics with lots of text, quiz questions, flashcards), ask Gemini to also export a Markdown version of the content. You get the interactive HTML and a plain-text version you can drop into Obsidian, Notion, or your project README. Two outputs, one prompt.

4. Pin the Canvas panel for repeated iteration

During long iteration sessions, the Canvas panel collapses if the model’s next response does not update the preview. Pin it via the pushpin icon (or Cmd+Shift+P in recent builds) so it stays open even when you are just chatting about the design without generating new code.

5. Respect the template ceiling – escape early to Custom app

The five named templates have heavy scaffolding to guarantee a polished first render, but that scaffolding can fight you when your needs drift. If you are three prompts into a “Web page” Canvas and keep getting polite-but-wrong responses, ask Gemini to “switch this to a Custom app so I can specify the structure freely.” You lose the template guardrails but gain total control over the output shape.

How GeminiDesktop implements Canvas

We are building GeminiDesktop with Canvas as a core feature.

Native side panel. Built with Tauri’s webview capabilities – fluid resizing, drag-to-resize layouts, Retina-resolution rendering. The preview is full-fidelity, not a scaled-down approximation.

Iterative AI editing. After initial generation, continue the conversation to refine: “Make the header larger.” “Change the blue to #2563EB.” “Add a fourth flashcard about mitochondria.” Each instruction updates the live preview with full conversation context.

Local export. Save Canvas outputs directly to your file system. Web pages as HTML files, infographics as HTML or images, quizzes and flashcards as self-contained HTML. All outputs are portable and work offline after export.

Multi-model Canvas. Because GeminiDesktop also supports Claude and GPT, you can direct different Canvas requests to different models: Gemini for creative layouts, Claude for code-heavy custom apps, GPT for long-form text inside templates. The side panel is model-agnostic.

Windows context: how Canvas works when you don’t have a native Windows app

Google did not ship a native Gemini Windows app. Windows users have two real paths to Canvas:

Browser / PWA. gemini.google.com on Chrome or Edge fully supports Canvas, including the side panel. Install it as a PWA for a pseudo-native feel. This works and is free, but it lives in browser memory, does not have a global hotkey without PowerToys Run, and competes with your normal browsing tabs for attention.
Native Tauri client. GeminiDesktop.app for Windows exposes the same Canvas feature set in a real Windows binary, with a global hotkey, proper app window management, and no 20 MB file limit (which the official “Google app for desktop” on Windows does enforce).

For the full explainer on why Canvas on Windows is not as well-served as on Mac – and which workflow fits which user – see native Gemini Windows app and the detailed Gemini Windows app vs Google app for desktop comparison.

What Canvas means for desktop AI

Canvas shifts the value proposition of a desktop AI client. A chat-only client competes on answer quality. A Canvas-capable client competes on output quality – which tool produces the most useful deliverables.

For desktop users, deliverables matter. You are at your computer to produce something: a document, a design, a piece of code, a teaching resource. A desktop AI that produces things directly – not just describes how to produce them – is categorically more useful.

FAQ

Does Canvas work offline? No. Canvas generation requires a round-trip to Gemini’s servers. The exported HTML, however, runs fully offline after you download it – no runtime call home.

How big can a Canvas output be? In practice, the model’s context window caps you at a few hundred KB of generated code per iteration. For anything beyond a simple web page or small app, you will want to scaffold the top-level structure in Canvas and fill in detail in a real editor.

Can I import my own data into Canvas? Yes, by pasting it into the prompt or attaching a file. For larger data files, paste a CSV snippet and describe the schema – Gemini will build the UI around that shape.

Is Canvas free? Canvas is available to all Gemini users, but heavy use counts against your rate limits. Gemini Advanced subscribers get substantially higher ceilings for complex Canvas generations.

Can I collaborate on a Canvas with someone else? Not in real time. The exported HTML is the share artifact – send the file or host it. For real-time collab, you are still better served by Figma, Google Docs, or a live code editor.

Does Canvas support dark mode / my design tokens? Yes, if you ask. Include your palette, typography scale, or design tokens in the prompt, and Gemini will respect them. For repeat use, paste your tokens into a “style context” preamble at the start of each Canvas session.

We are building GeminiDesktop around this principle. Canvas with native integration, live preview, iterative editing, and local export. If you want Gemini to be a creation tool on your Mac, not just a chat window, try GeminiDesktop.
