NoteGPT is a broad AI suite that summarizes almost anything. HoverNotes does one job brilliantly — it watches videos with you and turns every course, lecture, and tutorial into AI study notes, automatically, capturing the on-screen code and diagrams a summary skips.
See it in action
HoverNotes sits right beside the video and turns what you watch into AI study notes — automatically, as you learn, capturing the code and diagrams a transcript misses.

Watches the video live and writes structured AI study notes as you go
Captures timestamped screenshots of on-screen code, equations & diagrams
Saves everything privately to your own Obsidian vault
The honest comparison
Both are great — at different jobs. NoteGPT is a broad AI suite. HoverNotes is the focused tool for turning the videos you watch into notes you keep.
You learn from videos — courses, lectures, coding tutorials — and you want AI notes plus timestamped screenshots saved straight to your own Obsidian vault, fully private and local-first.
You want one cloud suite for everything — summarizing PDFs and articles, generating slides, images, voices, and writing — and video is just one of many inputs you summarize.
