Canvas is a side pane that opens next to the chat, giving you a focused workspace for viewing and editing AI-generated content. Instead of scrolling through code blocks in the conversation, you can open them in Canvas for syntax highlighting, live preview, editing, and export.
Opening canvas
When the AI generates a code block, HTML snippet, Mermaid diagram, or markdown block, an Open in Canvas button appears on the block. Click it to open the content in the Canvas pane on the right side of the chat.
Supported content types
| Type | Preview | Edit | Notes |
|---|
| Code | Syntax-highlighted display (Shiki) | Plain text editor | Supports all common programming languages |
| HTML | Live rendered preview in a sandboxed iframe | HTML source editor | Scripts run in a sandboxed environment |
| SVG | Rendered vector graphic | SVG source editor | Uses the same renderer as HTML |
| Mermaid | Rendered diagram | Mermaid DSL editor | Lazy-loads the Mermaid library on first use |
| Markdown | Formatted rich text | Markdown source editor | Renders with standard markdown formatting |
- Edit / Preview toggle — switch between editing the source and viewing the rendered output.
- Apply — save your edits back to the original message in the chat. Only appears when you have made changes.
- Copy — copy the content to your clipboard.
- Download — download the content as a file with the appropriate extension (
.html, .mmd, .svg, .md, or the original code file extension).
- Close — close the Canvas pane.
Editing and applying changes
- Click the pencil icon to enter edit mode.
- Make your changes in the text editor.
- Click the eye icon to preview the result.
- Click Apply to write the changes back to the source message in the conversation.
The Apply button only appears when the content differs from the original. A confirmation toast shows when changes are applied successfully.
