Build a document or prototype in Gemini Canvas

Move a complex deliverable into Canvas, iterate on structure instead of rewriting the whole chat, and export only after a final review.

Before you start

Canvas is designed for creating and editing longer artifacts such as documents, apps, slides or code. Available transformation and export options can vary by account and surface.

1. Start Canvas with a deliverable

Choose Canvas and describe the exact artifact: proposal, article, app prototype, slide outline or code. Give audience, constraints and acceptance criteria.

2. Create structure before polish

Ask for headings, sections, components or screens first. Fix missing logic and ordering before spending time on sentence-level style.

3. Edit one region at a time

Select or reference the section you want changed and state what must remain untouched. Controlled edits reduce regressions across a long artifact.

4. Preview the actual output

For code or interactive work, use the available preview and test the intended user path. For documents, read transitions, tables and headings as a whole.

5. Export only after a final pass

Check factual claims, links, placeholders and formatting. Then use the appropriate share/export path rather than treating the first generated artifact as finished.

Try this prompt

Create this in Canvas as a structured deliverable. First build the outline/components only. After I approve the structure, we will revise one section at a time. Preserve approved sections unless I explicitly ask to change them.

Common mistakes

Generating the entire artifact repeatedly; mixing structural and cosmetic changes in one request; never opening the preview; exporting with placeholder facts or links still present.

Finish check

The Canvas artifact has a stable structure, tested critical path or readable document flow, and no unresolved placeholders before export.

开始之前

Canvas 适合创建和编辑较长的成果物，例如文档、应用、幻灯片或代码。可用的转换与导出选项可能因账号和界面不同。

1. 以明确成果物开启 Canvas

选择 Canvas 后直接说明要做什么：提案、文章、应用原型、幻灯片大纲或代码，并给出受众、约束和验收标准。

2. 先搭结构，再润色

先让它建立标题、章节、组件或页面结构。逻辑和顺序没解决之前，不要把时间花在逐句修辞。

3. 一次只改一个区域

明确指定要修改的章节或区域，并说明哪些内容必须保持不动。受控编辑能减少长文档或原型里的连锁回归。

4. 真正预览最终形态

代码或交互内容要打开预览走一遍关键用户路径；文档则要整体检查章节过渡、表格和标题层级。

5. 最终复核后再导出

检查事实、链接、占位符和格式，再使用合适的分享/导出方式，不要把第一次生成的版本直接当成成品。

可以直接套用的提示词

请在 Canvas 中把它做成结构化成果物。第一轮只建立大纲/组件结构；我确认结构后，再一次修改一个区域。已经确认的区域除非我明确要求，否则保持不动。

常见错误

每一轮都重新生成整个成果物；一次请求同时做结构和外观大改；从不打开预览；占位事实或链接还没清理就直接导出。

完成检查

完成后，Canvas 成果物结构稳定，关键交互路径已经测试或文档阅读流畅，而且导出前没有遗留占位内容。

開始之前

Canvas 適合創建和編輯較長的成果物，例如文檔、應用、幻燈片或代碼。可用的轉換與導出選項可能因賬號和界面不同。

1. 以明確成果物開啓 Canvas

選擇 Canvas 後直接說明要做甚麼：提案、文章、應用原型、幻燈片大綱或代碼，並給出受眾、約束和驗收標準。

2. 先搭結構，再潤色

先讓它建立標題、章節、組件或頁面結構。邏輯和順序沒解決之前，不要把時間花在逐句修辭。

3. 一次只改一個區域

明確指定要修改的章節或區域，並說明哪些內容必須保持不動。受控編輯能減少長文檔或原型里的連鎖回歸。

4. 真正預覽最終形態

代碼或交互內容要打開預覽走一遍關鍵用戶路徑；文檔則要整體檢查章節過渡、試算表和標題層級。

5. 最終復核後再導出

檢查事實、連結、佔位符和格式，再使用合適的分享/導出方式，不要把第一次生成的版本直接當成成品。

可以直接套用的提示詞

請在 Canvas 中把它做成結構化成果物。第一輪只建立大綱/組件結構；我確認結構後，再一次修改一個區域。已經確認的區域除非我明確要求，否則保持不動。

常見錯誤

每一輪都重新生成整個成果物；一次請求同時做結構和外觀大改；從不打開預覽；佔位事實或連結還沒清理就直接導出。

完成檢查

完成後，Canvas 成果物結構穩定，關鍵交互路徑已經測試或文檔閱讀流暢，而且導出前沒有遺留佔位內容。
