How to Use Mistral Le Chat Canvas to Write and Edit Documents

Chat interfaces have a copy-paste problem: every revision means moving text in and out of the conversation. Mistral Le Chat solves it with Canvas, a split view where your document sits on the right and the chat stays on the left. Edits apply directly to the document.

It changes how you work, not just how you prompt. Here is the workflow that makes it worth using.

What is Canvas and how do you open it?

Canvas is a document pane in Le Chat. You open it by asking for a draft, then clicking Canvas, or by starting from the Canvas button directly. Both text documents and code files open in the same pane. The chat pane keeps full history, so you can reference earlier instructions while editing.

How do you draft a document in Canvas?

Write your brief in the chat, keeping the audience and length explicit.

• State the format: memo, blog post, release notes, email
• State the length in words or sections
• State the tone with one example sentence

Le Chat writes into the canvas rather than the chat bubble. From there your prompts become edit instructions, not regenerate instructions.

How do you revise without losing good paragraphs?

This is where Canvas earns its place. Instead of asking for a new version, highlight the section you want changed and describe the change. Only that section moves. Unhighlighted paragraphs stay exactly as written, which is the thing plain chat cannot do.

A useful habit: after each revision, ask Le Chat to list what it changed. It will enumerate the edits, and you catch accidental rewrites of text you had already approved.

Does Canvas handle code too?

Yes, and it is competent for small scripting tasks. It shows syntax highlighting and lets you edit inline. It is not a replacement for an IDE, because it has no project-wide file handling and cannot run a test suite. For a single function or a config file, it is fine. For a repo, use a proper editor.

Is Canvas available on the free plan?

Yes. Canvas is part of the free tier, not a Pro feature. Pro, around $14.99 per month, raises message limits and priority access, which matters if you iterate heavily. For occasional drafting, free is enough.

Where does it fall short?

The document is plain rich text, so there is no real style management, no tracked changes between collaborators, and no export to Word with formatting intact. Long documents eventually hit context limits and earlier sections drop out of what the model can see, so you should not treat a 10,000-word document as a single canvas project. Split it by chapter.

It fits solo writers and anyone producing internal docs. Teams needing review workflows and comments should stay in a real document editor.

Key Takeaways

• Canvas in Mistral Le Chat keeps a document beside the chat for direct editing.
• Highlight a section to change only that part; unhighlighted text stays untouched.
• Ask what changed after each revision to catch accidental rewrites.
• Canvas is available on the free tier, not just Pro.
• No tracked changes or formatted Word export; split long documents by chapter.
