Flexible organization Arrange notes with folders, tags, and pins. Collect unfinished checklist items in the task view. Search titles, text, and tags, then save useful combinations as Smart Folders. Portable content Export individual notes as Markdown or PDF. You can also export multiple notes by folder, keeping your writing accessible outside the app. Private Space Store private photos, videos, files, and notes in encrypted local storage. Configure automatic locking, an emergency lock, a separate entry phrase, and an optional decoy space.
