Write what you learn, link ideas as you go, and watch your notes become a map of what you know. Breef brings each note back for review, less often the more you remember.

For students and researchers who learn from lectures, papers and books, Breef is a study notebook that links everything you write into a map of what you know and brings each note back for review. Nothing to set up, and the reviews, quizzes and lecture notes come built in.
Learning scatters. Lecture notes sit in one app, highlights in another, and papers in a folder you rarely open. Nothing ties them together, and what you wrote is forgotten because you never go back to it.
