Snap any page from a print book or eBook. Add highlights, underlines, and notes, save text with OCR, then find your reading insights fast with tags and search.
Snap a page. Save what matters.
YomuMark is a reading notes app that lets you save pages from print books and eBooks, then organize them with highlights, underlines, handwriting, notes, and tags.
Use OCR to capture text from saved pages and keep the passages, ideas, and insights you want to remember—all organized by book.
It’s also perfect for anyone who doesn’t want to write directly in a physical book.
Keep your books clean while moving your highlights and notes into a digital space.
With tags and search, you can quickly find what you saved later and turn your reading into a personal collection of notes and knowledge.
