HoverNotes

HoverNotes is a Chrome browser extension for developers, students, and online course learners that generates structured, searchable Markdown notes while watching videos on sites like YouTube, Udemy, and Coursera.

Key capabilities include:

• AI video note generation from both audio and on-screen visuals, capturing code, equations, and diagrams that transcripts can miss
• Code extraction with syntax highlighting and contextual explanations powered by Google Gemini 2.0
• Timestamped screenshots inserted into notes, with links back to the exact video moment
• A split-view workspace that keeps video playback and notes side by side, plus multi-language note support

Pricing: Freemium, includes a free plan (try free, no credit card).

What makes it notable is its local-first storage that saves notes directly to the user’s computer (including directly into an Obsidian vault) for privacy and long-term ownership, with compatibility for Logseq and other Markdown-based knowledge tools. Latest version reported: 1.9.4.
