Create timestamped notes on YouTube and annotate any web page — all private, stored locally, and yours forever. No accounts. No subscriptions.
Capture key moments without pausing. Add notes linked to exact timestamps — they appear right in the video, exactly when you need them.
Annotate articles, documentation, and tutorials without leaving the page. Your notes stay exactly where you made them — no exports, no switching tabs.
Select any text, highlight it, and attach your thoughts. Everything stays private and visible only to you — like marginalia for the web.
Sketch directly on maps, charts, or any visual content. Perfect for visual learners who think with their hands.
