ChangeDown

Track changes in markdown — for humans and AI agents.

Every edit is attributed, every decision recorded. The file carries its own deliberation history — not in a sidebar or a separate system, but in the text itself. Anyone reading it sees not just what the document says, but the reasoning that shaped it.

For humans — a VS Code extension with the workflow you know from Word and Google Docs. Accept, reject, comment, navigate. The comment panel keeps discussion next to the text — no context-switching to review.

For agents — six MCP tools that read and write CriticMarkup directly. Hash-verified coordinates prevent stale edits. 2.3× fewer tokens than raw file replacement.

For everyone — plain text. Readable in any editor, diffable in git, parseable by anything. No lock-in. The format is already markdown. For teams — shared review workflows with approval chains, amendment history, and compaction.
