Mento is the notes app that quizzes you back. Capture what you learn, organize it your way, and practice until it sticks — so you walk into every exam knowing it. Most notes go somewhere to be forgotten. Highlighting feels productive, but without practice it's just reading. Mento closes the loop: your notes, PDFs, and lectures become flashcards, and spaced repetition schedules every review so five minutes a day is enough.
