Questions

What is Remark?
Remark is a native macOS app that lets you annotate Markdown files with inline comments. Select text, write what needs fixing, and your AI coding agent reads the comments, applies the changes, and marks them done.
Does Remark work with Claude Code, Codex, and other agents?
Yes. Remark ships with a CLI that outputs structured JSON. Any agent that can read tool output — Claude Code, Codex, Cursor, or your own scripts — can consume and resolve Remark comments.
Is it a subscription?
No. Remark is a one-time purchase of $17. You get the app, the CLI, all current features, and every future update. No account required, no cloud, no recurring fees.
What happens to my comments when the document changes?
Remark re-anchors comments to the correct text after edits. If the original text is gone entirely, the comment is marked as orphaned so nothing gets lost.
