Build a personal library
• Save notes and link each one to the book it came from.
• Group notes into Collections by theme, project, or course.
• Browse your library by book, by author, or by date.
Find anything
• Hybrid search combines full-text matching with semantic AI, so you can
search by what you meant — not just the exact words you wrote.
• Ask Mark questions about your library through the built-in chat.
Pair the Mark pen (optional)
• Connect over Bluetooth to sync captures from your Mark pen.
Made for everyday reading
• Offline-first — your library works without a connection.
• Sign in once and pick up on any device.
