HoverNotes

HoverNotes is an AI note-taking tool for video learning. According to its page, it watches the screen rather than only reading captions, so it can capture code snippets, diagrams, and equations as they appear, and it works even when a video has no captions. Notes are formatted with syntax-highlighted code blocks, markdown headings, and bullet points, and can be saved to a local Obsidian vault as pure markdown. Additional features listed include timestamped screenshots, an ad-free side workspace beside the video, variable playback speed from 0.1x to 16x with pitch preserved, Live Translate for hearing videos translated into another language, and Hovie, an assistant that answers questions about notes, transcripts, and screenshots. The page lists many supported platforms, including YouTube, Udemy, Coursera, Bilibili, LinkedIn Learning, Canvas, Blackboard, and local video files, and reports 500,000+ notes captured and a 4.6 rating from 104 reviews.
