HoverNotes: AI-Powered Video-to-Obsidian Notes Converter

Introducing HoverNotes: Where Video Learning Meets Obsidian Knowledge

HoverNotes is a purpose-built Chrome extension that bridges the gap between passive video watching and active, permanent knowledge building. It intelligently converts instructional videos—from YouTube coding walkthroughs and Coursera lectures to Udemy deep dives and internal training reels—into rich, searchable, timestamped Obsidian notes—*without ever sending your video data to the cloud*. Leveraging on-device AI analysis, HoverNotes extracts key concepts, detects and formats code blocks with syntax awareness, captures contextual screenshots at any moment, and structures everything in clean, portable Markdown. Your notes stay 100% local, encrypted in your own Obsidian vault—giving you full ownership, zero tracking, and seamless integration into your existing second-brain workflow.

Getting Started in Seconds

Install the HoverNotes extension from the Chrome Web Store, then launch it while playing any supported video. A lightweight, non-intrusive panel appears beside the player—no tab switching, no copy-pasting. As the video plays, HoverNotes listens, interprets, and documents in real time: summarizing explanations, isolating executable code, and letting you capture frame-accurate screenshots with one click. Every output syncs instantly to your local Obsidian vault as human-readable .md files—ready for linking, tagging, and refining using Obsidian’s full ecosystem.

FAQ from HoverNotes

What is HoverNotes?

HoverNotes is a privacy-first Chrome extension that transforms educational videos into structured, searchable Obsidian notes—powered by on-device AI. It captures concepts, code, visuals, and context in real time—keeping everything local, secure, and deeply integrated with your knowledge system.

How to use HoverNotes?
