- For
- Mac users who want plain-text-accessible notes
- Worth noticing
- The app requires macOS 12 or later and supports both Apple Silicon and Intel; one Pro key covers one Mac at a time.
Field notes
The page gives a default storage path and says the file can be moved in Settings; it also describes syncing through a user’s iCloud Drive or Dropbox rather than through a Plainkeep account. The site says concurrent changes preserve both versions. Its stated gaps are concrete: no images, preview, tags, subfolders, or apps for iPhone, Windows, and Linux.
