How Mark Works
A lifetime of knowledge.

Scan your pages
Slip Mark into your book. Its camera silently scans the pages you just read — physical or digital text, it captures everything automatically.

Record your thoughts
Voice notes, highlights, reactions — captured instantly. Mark turns your spoken thoughts into structured, searchable knowledge while the ideas are still fresh.

Retrieve anytime
Search your entire reading history by concept, book, or idea. Smart reminders resurface key insights using spaced repetition — so knowledge actually sticks.

“I got into reading and self-help books and wanted a tool that could organize and keep track of all my thoughts, notes, and insights. I hope Mark can do the same for other everyday readers.”
