The problem
Your book is full of great ideas. Your memory is not.
Highlighting is easy. Remembering what you highlighted takes a second step. That is where many readers lose their best ideas.
Notes take too much time
Typing, sorting, and explaining ideas interrupts the reading flow and quickly gets postponed.
Review never happens
Without a review system, even strong ideas become blurry after a few days.
The solution
Scan. Understand. Remember.
Marook turns a highlighted page into a structured learning moment: capture the text, understand the meaning, save it as a card, and review it later.
