LessonCues VS GitHub Surf

LessonCues's answer

It turns any part of a YouTube video into a link that plays just that moment, and then helps you practise it. You set a start and an end to a tenth of a second, and the clip stops or loops. Each clip can keep its own practice settings: speed from 0.25× to 2×, a number of repeats, a pause between loops, and a speed trainer that starts slow and speeds up a little every time. Clips from different videos can then go into one lesson with your own notes, Google Slides and full videos, which you can present full screen or print as a handout with a QR code for every clip. Nothing is downloaded: everything plays in YouTube's official player, so creators keep their views.

LessonCues's answer

Choose it if the moment is what matters. A timestamp link only sets where a video starts; LessonCues also sets where it stops, loops that part, and remembers how you want to practise it. Most lesson platforms are built around slides and quizzes; LessonCues is built around the exact seconds of a video, so it suits practising a riff, a dance step, a technique or a phrase as much as teaching a class. It's free, needs no account to make your first clip, has no ads, and doesn't create student accounts: anyone with the link can watch. If you need quizzes, grading or student tracking, a full classroom platform is the better fit.

LessonCues's answer

People who teach or learn from YouTube videos: teachers who want to show just the part of a video that explains something, music and dance learners and teachers who loop and slow down a passage, sports and fitness coaches who share technique and give feedback on the exact moment, and language learners who repeat a phrase until it sticks. It's also handy for anyone who wants to send a friend one moment of a video instead of "skip to 4:12".

LessonCues's answer

For years I sent people YouTube links with notes like "watch from 4:12, the good part ends around 5:30". Nobody ever stopped at 5:30. YouTube once had a Clip feature for this, and it was retired, so I built my own: pick a start and an end, and share a link that plays just that moment. Then it grew. As a musician trained in Hindustani classical music, I know that learning mostly means repeating a small phrase until it's right, so clips got practice controls. And clips became lessons, so teachers can put moments from different videos in order and present them in class. It started as "YouTube Clips" and was renamed LessonCues in September 2026 to follow YouTube's branding rules.
