StudyStamp

Privacy-first YouTube study companion: timestamped revision notes and a focus timer. Notes stay on your device.

Stop losing the important parts of long YouTube lectures. StudyStamp adds a small, draggable study panel to YouTube watch pages. Save the exact moment with one tap or Ctrl+Shift+S, write a note, tag it (Important, Confusing, Rewatch, Exam, Definition, Diagram, Example), and organise notes into folders by module or topic. Click any saved timestamp to jump the video straight back to that moment. A built-in focus timer keeps sessions honest: set your own focus and break lengths (default 25/5), get a chime when time is up, and see your session history. The dashboard shows every saved video with search, tag and folder filters, and one-click Markdown export for Obsidian, Notion or Google Docs. Privacy first: no account, no server, no analytics, no AI. Everything is stored locally in your browser and you can export or delete it any time. The extension only runs on youtube.com and asks for nothing else.
