- AI edits you can see and undo. Whatever an assistant writes is tinted and labeled with its name, and one tap undoes it. - Version history. Every change keeps the previous version, with who made it: you on iPhone, you on Mac, or which AI. - Apple Notes import on the Mac, and Evernote (.enex), Google Keep (Takeout) and Markdown or text imports on the Mac and iPhone, bring your notes over. - Sync between iPhone and Mac in about half a second. - Connect ChatGPT, Claude, Claude Code or Codex. You approve each connection in the app and choose read-only or read-and-edit.
- Apple Notes layout and behaviour. Folders, a note list grouped by date, pinning, search, multi-select, Recently Deleted. When in doubt, it does what Notes does. - Markdown underneath, formatted on screen. Headings, bold, italic, underline, strikethrough, code, quotes, links. The markdown syntax stays out of sight. - Lists like Notes. Checklists (ticked items slide to the bottom), bulleted (), dashed (-) and numbered lists. Return continues a list, Tab nests it. - Tables you edit cell by cell, including typed columns (number, date, yes/no). - Sub-notes. Link a note inside another, like a folder inside a page. - Files and images inside a note: paste, drag in, or attach. PDFs open in Quick Look. - Live sync. Typing on one device shows up on the others in about half a second. Edits made on
