Mark II is a smart bookmark that captures your physical notes and ideas, and turns it into organized insights for you to revisit later CAPTURE WITHOUT LEAVING THE PAGE Scan a passage and it's saved, at 99% text accuracy, with any missing letters or words reconstructed automatically. Or hold to record a voice note instead. No unlocking your phone, no typing, no losing the thread of the chapter. It works across your whole reading life — hardcovers, paperbacks, printouts, research papers, Kindle, iPad, and handwriting (beta). 30+ languages. A LIBRARY THAT BUILDS ITSELF Scan a book's ISBN once (beta) and everything you capture from then on files itself under the right title. No folders to design, no tags to maintain, nothing named twice. Over months, it becomes a catalogue of what you've actually read — not a system you have to keep feeding. FIND THE QUOTE YOU HALF-REMEMBER Search for a fragment and get the passage back with its source. Filter by topic, theme, or the moment you captured it. Copy it straight into whatever you're writing. TALK TO WHAT YOU'VE READ Chat with your own highlights and annotations. Trace an idea across different books. Ask about the thing you know you read but can't place. Mark AI answers from what you've captured and nothing else — it won't invent a passage, and it won't summarize a book you never opened. FITS THE SYSTEM YOU ALREADY HAVE Integrations with Readwise, Notion, and many more apps to come. Mark isn't asking you to move in. It's asking you to feed what you've already built. WORKS WHEREVER YOU READ Bluetooth only — pairs like AirPods. Captures save on the device when you're out of range and sync the moment you're back. A single USB-C charge lasts about a week of heavy reading. YOUR NOTES, HELD CAREFULLY Highlights and voice notes are encrypted and stored on AWS in North America. We don't hold personally identifiable information alongside your library, and you can request deletion of your data at any time. WHO IT'S FOR Students who annotate. Researchers who cite. Readers who underline in pencil and mean it. Anyone who has closed a book and been unable to say what was in it. WHAT'S FREE Downloading Mark is free, and so is everything core: highlighting, audio capture, auto-organization, and basic AI chat. An optional subscription unlocks the heavier AI features and advanced integrations. REQUIREMENTS The Mark II device is required for scanning and voice capture. Each device pairs to one account at a time. iOS only. Support: Support@mark.engineering Privacy Policy: thinkwithmark.com/policies/privacy-policy
