From video to usable notes
Use the parts you need. Every step works as a separate free tool.
02Find the main ideas
Summarize the lecture
Use the same video URL to get a short AI summary and key takeaways. Treat it as a starting outline, then check names, formulas, and claims against the lecture itself.

Use timestamps to review
Keep timestamps visible in the transcript so you can jump back to a difficult explanation. If you want a chapter-style outline, paste the transcript into the timestamp generator and check its suggested times against the video.

Make the notes your own
Start with one question you want the lecture to answer. Scan the transcript for relevant sections, then use the summary to identify what you may have missed. Write your final notes in your own words instead of copying the whole transcript.
Captions can mishear technical terms, names, and equations. AI summaries can leave out context. Check important details in the original video, especially before citing a lecture or using it in an assignment.
For a quick revision sheet, save the video link, your key takeaway, and two or three timestamps that lead back to the explanation. That gives you a short route back to the source when you study later.
Common questions
Can I use a lecture without captions?
The transcript and AI summary need an available caption track. If the video has no captions, these tools cannot extract its spoken text.
Can I study a lecture in another language?
The transcript extractor lets you choose among the caption languages available on that video. Language options depend on what the video provides.
Does the summary replace watching the lecture?
Use it to orient yourself or review, then check the lecture for examples, diagrams, equations, and context that text or a short summary may miss.
How do I keep a time-linked note?
Keep timestamps visible in the transcript and record the time beside your note. Open the original video at that point when you need to revisit the explanation.
