NoteNestAI

The core workflow is upload-and-extract: students feed in lecture slides, handouts, or image-based PDFs and the tool produces condensed notes, practice questions, and flashcards. Mastery tracking identifies which topics are still shaky, so revision is targeted rather than random. Collaborative course workspaces let study groups share and build on the same notes — one person uploads, everyone benefits. The free tier exists but the vendor page makes clear that full AI summarization is a paid-only feature, so students who hit the free-tier ceiling quickly face an upgrade decision. There is no API and no self-hosted option, which means your course data lives on NoteNest's servers.
