For students
Turn your YouTube lectures into notes you can review
Take timestamped notes while you watch, turn key moments into study cards and return to the exact passage behind every idea.
A lecture you watched is not a lecture you kept
You follow a clear explanation, nod along, and two days later the passage that mattered is gone. Lectures and tutorials are made to be watched, not to be found again.
Writing everything in a separate document cuts the link to the video. You no longer know which minute held the explanation, so you scrub the whole video again before an exam.
A workflow you can repeat
-
Group each course in a playlist
Put each course in a playlist or feed so every session starts from a clear goal.
-
Take notes while you watch
Add a timestamped note for each idea that matters. It stays linked to the video and its exact moment.
-
Turn a key point into a study card
Write the question and the answer. The card keeps the passage from about 20 seconds before to 10 seconds after your moment.
-
Review what is due
Cards come back on a spaced schedule. Reveal the answer, replay the passage, then grade it Again, Hard, Good or Easy.
What you use it for
-
Timestamped notes
Each note reopens the video at the moment you wrote it, so you can return to the explanation without scrubbing.
-
Search across all notes
Filter every note by keyword, across all your videos, to find a definition again in seconds.
-
Transcripts when captions exist
When YouTube provides captions, search the transcript and follow the line that matches playback.
-
Study cards with spaced repetition
Write a question and an answer at a key moment. Each review is graded Again, Hard, Good or Easy, and the next due date adapts.
-
Playlists and feeds by course
Group courses by subject or exam, and switch between them without losing your notes.
-
Private notes
Notes saved to your account stay private to it and are available in the web app wherever you sign in.
What ReplayGlows is not
- Not a course or a tutor: you write your own questions and answers. AI drafts are optional, use your own key and belong to Pro.
- Not a grade guarantee: it organizes your review. It does not measure or promise results.
- Not a classroom tool: nothing is shared with classmates, and there is no LMS integration.
- Not every video site: the web app works with YouTube, and the extension only controls speed on supported HTML5 video sites.
- Free plan limits: 10 videos, 50 notes per video, 3 playlists and 50 study cards (10 per video).
