Text appears as the video plays — automatically, with no setup. Works with YouTube, Coursera, Zoom, Udemy, or any video platform.
Edit while you watch
Click anywhere to add notes, highlight in 5 colors, bold key concepts, delete tangents. A live document, not a locked feed.
Timestamp sync

Export with all your formatting — bold, highlights, headers, bullet points — straight to Notion, Obsidian, or Google Docs.
