Antigravity-style review workflow for markdown in VS Code: read the rendered
preview, leave inline comments on the parts you want changed, then hand the
whole review to Copilot to apply.
How to use
Open a markdown file and click the comment icon in the editor title bar
(or run Markdown Review: Open Preview with Comments).
In the preview, select any text and click 💬 Add comment. Write your
feedback and press Ctrl+Enter (or the Comment button).
Comments appear highlighted in the preview and listed in the sidebar,
where you can resolve, reopen, delete, or jump to the source line.
Click Submit to Copilot — all open comments are compiled into a
review prompt and sent to Copilot Chat in agent mode so it can edit the
file. If chat can't be opened, the prompt is copied to your clipboard.
Comments are stored per file in workspace state and survive reloads. The
preview re-renders live as you (or Copilot) edit the markdown source.
