Your notes are plain .md files stored on your device. No account, no sign-in, no servers of ours โ€” and if you want them on your other devices, you can keep the folder in your own iCloud Drive. Open them, back them up, move them, or edit them in any other Markdown app. Noteline works fully offline and stays out of your way. Every note is plain Markdown โ€” the same format AI tools read and write โ€” so your notes stay usable by whatever you reach for next. It's the calm, focused place to think, take notes, and write.
