Add to Prism

Save YouTube videos to Prism projects, take timestamped notes, and focus YouTube on one project - or hide Shorts and comments.

Prism turns YouTube into a focused learning tool. This extension connects youtube.com to your Prism library. SAVE • One click on any watch page saves the video to a Prism project — or right-click any YouTube link and choose "Add to Prism". • Pick a default project in the popup and saves skip the picker entirely. • Videos already in your library get a Prism badge on their thumbnails, and the button shows which project they're in. LEARN • The "Note" button captures the exact timestamp you're watching and opens a ready-made note in Prism. • Continue watching: jump back into your recent Prism videos straight from the popup. FOCUS • Focus mode: choose one of your projects and YouTube shows only the videos in it — home, search, and recommendations included. Prev/next buttons step through the project like a playlist. • Learning mode: hide Shorts, comments, and the home feed for distraction-free studying.
