RewatchKit — YouTube Clip Playlists, A-B Loop & Timestamped Notes

Build playlists from parts of different YouTube videos and play them in order. Loop any part (A-B repeat). Add timestamped notes.

Put the parts you want from different YouTube videos into one playlist, and play them in the order you choose. Mark a start and an end in each video. RewatchKit saves the times, not the video files, and plays each part on YouTube. You can also loop a single part (A-B repeat) and add notes with timestamps. RewatchKit is a Chrome extension for YouTube. It doesn’t download, cut or re-upload videos. WHAT YOU CAN DO • Clip playlists: Put parts of different videos in one list, in your order, and play them one after another. Repeat the whole list if you like. • A-B loop: Set a start and an end and repeat only that range, before or after you save it. The loop keeps going when you switch to another tab (reloading the page stops it). • Timestamped notes: Write as you watch, then click a timestamp to go back to that moment. • Save while you watch: Press Start here, then Save to here, under the video title. Or press the E key twice. You can also save the last 15 seconds in one press. The key and the number of seconds can be changed in settings. • Playback settings for a list: Speed (0.5×–2×), a pause of 2 or 5 seconds between clips, number of rounds, and a stop timer. • Find it again: Search clips, notes and videos, or filter by favorites and tags. For videos with chapters, you also get a chapter list for jumping to each section. WHERE IT HELPS • Music practice: The warm-up from one lesson, the solo from another, the outro from a live session. One list for tonight. • Workouts and yoga: Line up moves from different videos, add a short pause between them, and run the list again. • Languages: Loop a line you missed until you catch it. Add a pause between clips and repeat each line aloud. • Favorite moments: Play the best parts of different shows in a row. • Lectures and tutorials: Go straight back to the few minutes or the step you need. YOUR DATA Your notes and clips are saved in Chrome on your device, not on our servers. You can export a backup file (JSON) at any time. Uninstalling can make your saved items unavailable, so export first. RewatchKit itself doesn’t include analytics or advertising code. Playback and thumbnails connect to YouTube. Privacy policy: https://www.tomu.studio/rewatchkit/en/privacy/ GOOD TO KNOW • Made for standard YouTube video pages (youtube.com/watch) in desktop Chrome. English and Japanese interfaces, light and dark themes. • It doesn’t work with Shorts, live streams, videos embedded on other sites, YouTube Music or other video sites. • RewatchKit doesn’t download or merge video or audio files. If a video is deleted or made private on YouTube, its clips can no longer play. • Clips play in YouTube’s own player, inside the library page or in a YouTube tab. Switching videos takes time to load, and ads or autoplay limits can stop playback. • Chapters are read from the description and comments already loaded on the page. Not every video has them. RewatchKit is made by Tomu Studio. It is not an official Google or YouTube product. Help: https://www.tomu.studio/rewatchkit/en/support/
