Mark II Turns Highlighting a Physical Book Into Searchable Notes

Mark II is a smart bookmark scanner shaped like a highlighter, built to capture ideas from a physical book without pulling out a phone or laptop. The device works on both printed pages and screens. Several people from the tech and media world, including an investor at A16z, an executive editor at Bloomberg, a partner at A24, and an editor at Stripe Press, publicly expressed interest in the product shortly after it was shown, describing it as a genuinely new category of device.

Three Ways to Capture a Thought

Mark works through three core actions. Highlight mode picks up a passage by holding the device and brushing it across the text, with a light confirming the capture happened. Speak mode lets someone record a voice note simply by holding the device and speaking, then releasing to send the note. Revisit mode pulls up everything captured so far, letting a person organize, search through past notes, or ask questions directly about ideas they've already saved.

Reading Handwriting in Over 100 Languages

Mark is built to recognize handwriting on both paper and digital screens, supporting more than 100 languages. The company specifically shows the device reading Chinese, Arabic, and Japanese scripts alongside standard Latin text.

Turning Scattered Notes Into One Searchable System

Mark organizes what it captures into four functions: organizing ideas, searching old notes, resurfacing past insights, and sharing them with other people. The device syncs directly with Notion, Obsidian, Readwise, Evernote, Apple Notes, and Bible study apps, and includes a one-click migration tool that imports existing notes from whichever app someone already uses rather than requiring them to start over from a blank system.

Built Like a Highlighter, Weighted Like Earbuds

Mark's body combines aluminum and ABS plastic in a double-injection unibody design. The company describes its weight and feel as closer to a pair of AirPods than a typical piece of hardware. Battery life runs more than a week per charge, recharges over USB-C, and the device connects to a companion iOS app over Bluetooth. Notes stay accessible without an internet connection, though some features in the app require one to work. Shipping is planned for North America first.
