Summarize YouTube videos and comments with AI. Read transcripts, save timestamped notes, and loop sections — all in one panel.

Summarize YouTube videos and comments with AI. Key points in seconds. SpaceTube adds an all-in-one panel right on the YouTube watch page. Summarize, search, loop, and save videos from a panel beside the player. No new tab, no copy-pasting links into another site. Get the key insights in seconds with AI — then use transcripts, comment summaries, section loops, bookmarks, and folders to actually learn, organize, and return to that video. SpaceTube enables you to: ✅ AI YouTube Video Summary — Get the key points in seconds. Lectures, podcasts, interviews, reviews — get the gist without watching the whole thing. ✅ Comment Summary — The top comments, summarized. See the overall reaction without scrolling. ✅ Full Transcript + Click-to-Seek — The complete, time-linked transcript instantly. Click any line to jump the video there. ✅ Section Repeat (A–B Loop) — Loop the best part of a song, a tricky phrase in a language lesson, or a dense explanation — as many times as you need. ✅ Timestamp Bookmarks — Mark the moments that matter and snap back to them anytime. ✅ Folders — Save and sort videos into your own folders. ✅ Player Controls — Playback speed, volume, and precise seeking, right from the panel. ✅ One-Click Copy — Send any summary or transcript to your clipboard — notes, Notion, anywhere. ✅ Native Dark & Light Mode — Blends into YouTube instead of fighting it.
