The name “Glassine” alone was already reserved on App Store Connect by someone else, though no app by that name has shipped. The listing is Glassine Writer; the app, its window, its icon and its files are all still Glassine.
iCloud Drive/Glassine in Finder, one .md file per document. File → Reveal Library in Finder takes you there. The App Store version’s default library is an iCloud folder of its own that Finder also shows as “Glassine” in iCloud Drive, with the app’s icon. See files and saving.
Yes. Double-click it in Finder (or Open With → Glassine), drop it on the Dock icon, or File → Open… (⌘O). It opens in place, edited and saved where it is, and shows under Elsewhere in the sidebar while it is open; File → Add to Library copies it in. To make Glassine the default for every .md file: Get Info on one in Finder, choose Glassine under Open with, Change All…. The files page has the details.
Yes. Settings → Library → Sync keeps the library in a private GitHub repository of yours; any Mac with Glassine and a token for that one repository has the same documents, and nothing else about your accounts touches it. Every version of every note is kept in the bargain. See sync with GitHub — and check what your employer’s policy says about personal files on the machine first.
Yes. Point Settings → Library at any folder — an Obsidian vault, a Dropbox folder — and Glassine reads and writes the same plain Markdown as everything else. Two apps can have the folder open at once; if both change the same file, Glassine keeps your edits and saves the other version beside the file as … (conflict).md.
Because nothing needs saving. Glassine writes the file half a second after you stop typing and every few seconds while you type; the dot at the bottom-left tells you where things stand, and File → Save Now exists for reassurance. The key went to the thing you do all day.
Only text. @September 5, 2026, - [x] done, #ideas. Glassine draws capsules, boxes and colours around ordinary Markdown and adds nothing to the file that another app would trip over.
No. There are no accounts, no analytics, no crash reporting. The direct-download version asks GitHub once a day whether a newer release exists, and you can turn that off. The App Store version holds the sandbox’s outgoing-connection permission only because Review’s web view cannot start without it, and never opens a connection of its own. See privacy.
Both sides changed the same document — this Mac and another, or Glassine and another app — and Glassine kept your version, saving the other beside it so nothing was lost. Open both, keep what you want, delete the rest. If the file dates from the very first build (September 1, 2026), it is a false alarm from a bug since fixed and safe to delete.
Not yet. Right-click → Move To does it, and ⌘Z undoes it. Dragging within a list — a task box, a bullet, a number — to reorder items does work.
Not yet. The files are in iCloud Drive, so any Markdown app on iOS can open them meanwhile.
One window, one library, by design. Switch libraries under Settings → Library.
Glassine keeps running with its window closed. Window → Glassine brings it back, so does clicking the icon in the Dock, and so does any command that needs the window — ⌘N, ⌘1, ⌘2, ⌘F, ⌘, — from the menu bar.
PDF only, in the current Review style (⌘⇧E). For anything else, the files are plain Markdown; Pandoc and its relatives work on them directly.
Help → Copy Debug Info (⌘⌥⇧D) puts the editor’s geometry and every setting on the clipboard. Paste it into an issue at github.com/a-libre/glassine/issues with a line about what you expected.
Yes. Glassine watches its own main thread; whenever it fails to answer for a second, the stack of what it was doing is written to ~/Library/Logs/Glassine/stall-….txt (and a line goes to the unified log under the subsystem com.alexlibre.glassine, category watchdog). Attach the newest file to an issue and the freeze can be read rather than guessed at. Nothing is sent anywhere by itself.
