Record the lecture. Notevo turns it into notes you can actually read, and marks every spot where your professor said βthis will be on the examβ, with the exact second and their own words. AFTER EVERY LECTURE β’ Notes like a textbook chapter: sections, definitions, formulas, examples. β’ Exam signals: when your professor says it's on the exam, repeats a point, writes it on the board or hints at a question, Notevo marks it. Tap the timestamp and hear them say it. β’ A course book: every lecture merged by topic, with a table of contents and an exam probability for each topic. PREDICT THE EXAM β’ Upload past papers as photos or PDF. Notevo works out your professor's style: question types, topics, difficulty. β’ Get a predicted exam in the real format, with the reason each question could come up and a link to the moment in the lecture. β’ Take timed mock exams. Photograph your handwritten answers and get them graded, with what's missing. Predicted exams are estimates. Notevo writes them from your own lectures and the past papers you upload; they are not real or leaked exam questions. STUDY TOOLS β’ Flashcards with spaced repetition, made from your lectures β’ Quizzes by lecture or topic β’ Chat with your course: every answer cites the lecture and the second β’ Podcast mode: any topic as a 5β12 minute audio episode β’ Oral exam practice: Notevo asks, you answer out loud β’ Cheat sheet, formula sheet, mind map and a day-by-day exam plan RECORDING THAT KEEPS UP β’ Keeps recording with the screen locked or the app in the background β’ Tap Important during class to mark a moment β’ Photograph the board or slides; they land next to the right section β’ Live transcript, live translation and βwhat did they just say?β β’ Import audio, video or PDF slides GROUPS Start a group with your classmates.
