Developers emphasize that while people may prefer paper books, they cannot match the engagement, accessibility, and efficiency of electronic ones.

Crafted from grade 5 titanium, the Mark bookmark syncs with other electronic devices and offers a range of useful features:

• summaries of read pages — the gadget generates personalized summaries based on user preferences;
• access to a reader community — Mark allows users to share opinions and discuss material studied;
• personalized statistics — the bookmark displays reading pace and progress, offering tips for improvement.

Mark adapts to the individual characteristics of the reader, selecting the best quotes, statistics, themes, and ideas. Users can record their thoughts and notes in addition to the generated personalized annotations.

“Mark acts as a second brain, collecting all your knowledge,” the developers noted.

The bookmark is available for pre-order at $129.

Earlier in January, at the Consumer Electronics Show, various teams presented intriguing and sometimes absurd AI-driven products.
