- For
- Markdown writers who want local files and review comments
- Worth noticing
- The page says untouched blocks remain byte-for-byte identical and flags a vanished comment passage rather than deleting its thread.
Field notes
The homepage describes documents as ordinary .md files in user-managed folders, with images stored beside their documents and no account or server required. Review threads sit outside the Markdown and can attach to a passage or a whole block; if their passage disappears, the page says the thread is flagged rather than lost. The feature list also includes snapshots, filtered search, exports, and side-by-side conflict review.
