Mark, a reading hardware startup, said it has raised $1 million and is launching Mark II, a $159 AI bookmark, in a thread on X. The post, signed by Eason Tang (@EasonTang23), framed the device as a way to bring AI into physical reading without pulling out a phone.

"We raised $1M dollars to reinvent how people read. Introducing Mark II - a $159 AI bookmark," the account wrote, adding that attention has shifted to ragebait and summaries and that books "sit unread." The pitch: read your paper book as usual, then scan a quote or whisper a thought and slide the device back in like a bookmark. Preorders are live on the Mark preorder page.

According to the thread, the companion app saves quotes and voice notes, sorts them by book and concept, surfaces connections across your reading, and can summarize what you have captured. The team said language support includes English, Korean, Japanese, Arabic, Chinese and "100+ more languages," with North America shipping first and global shipping in progress.
In replies, Tang framed the product as a purpose-built tool to capture quotes and whispered thoughts without reaching for your phone: "We think that your personal habits are sacred and deserve purpose-built tools... instead of creating another reason for you to reach for your phone :)." The company is also hosting in-person demos in New York this week, per replies in the thread.
