HoverNotes vs StudyFetch

It depends on what you need. For capturing notes while you actually watch a video, HoverNotes is purpose-built: it follows any video in your browser in real time, captures timestamped screenshots of on-screen code, equations and diagrams, and saves AI study notes to your Obsidian vault. StudyFetch is the stronger choice if you want an all-in-one study platform with Spark.E, a conversational AI tutor grounded in your uploaded course materials.

StudyFetch is an AI study platform built around Spark.E, a tutor that chats about uploaded PDFs, slides and lectures and generates flashcards, quizzes and practice tests. HoverNotes watches the video with you in real time, captures timestamped screenshots of the code and diagrams the moment they appear, and writes AI study notes straight to a local Obsidian vault.

StudyFetch's Live Lecture Assistant transcribes a class or recording and generates notes from the audio, but it doesn't capture the visual frames — so the on-screen code, equations and diagrams aren't saved as images. HoverNotes follows the video as it plays and grabs exactly those moments as timestamped screenshots, which is what makes it strong for coding tutorials and diagram-heavy lectures.

StudyFetch has a restrictive free tier (10 Spark.E chats, 1 study set, 2 uploads), with Base at about $4.99/month and Premium at $7.99/month billed annually. HoverNotes is free to install, with paid plans for heavier use. HoverNotes is also local-first: your notes live in your own Obsidian vault rather than StudyFetch's cloud.

Choose StudyFetch if you want an all-in-one study platform with a conversational AI tutor — upload your PDFs, slides and lectures and have Spark.E explain concepts, generate flashcards, quizzes and practice tests, plus a Live Lecture Assistant. Choose HoverNotes if you learn from video and want notes and screenshots captured automatically as you watch, saved to your own vault.
