WHY COURSENOTE • Turn a long lecture into structured, searchable notes • Import a video or audio file, or record a lecture with your device microphone • Every section has a timestamp — tap it to jump back to the source material • Board writing, formulas, and tables are captured into the notes, not just a raw transcript • Generate self-test questions from your notes and grade them one by one • Ask questions about your notes, find related notes from a photo, and get AI explanations • Annotate directly on your notes with Apple Pencil HOW IT WORKS 1. Add material: import videos, audio, or PDFs from Files, Photos, or other apps; you can also record audio in CourseNote 2.
