The gap is what happens before you open the app
Both tools do roughly the same thing once material exists: point them at a document and get a study set back. The difference is upstream. StudyFetch begins when you hand it a file, which quietly assumes your course arrives as files — and a lot of courses do not. A professor who lectures from memory, works through problems on a board, or spends twenty minutes on the one distinction that always trips people up is generating the most valuable material in the course, and none of it lands in a PDF. NoteLinkAI records the lecture itself, transcribes it, and treats that transcript as a first-class source alongside anything you upload.
