Summarize a YouTube lecture in a minute
Sumvid summarizes a recorded YouTube lecture from its captions: paste the link, and in about a minute you get a one-sentence summary plus 3–7 key takeaways, each starting with a timestamp that jumps back to that moment in the lecture. It works on long recordings and in any language, so you can review a 90-minute class before the exam, or decide whether a talk is worth watching at all.
How it works
Three steps
- 1. Paste the lecture link. Any YouTube URL works: a course playlist video, a conference talk, or a recorded seminar.
- 2. Pick a language. The summary is written in the language you choose, whatever language the lecture was given in.
- 3. Review with timestamps. Click a takeaway's timestamp to open the lecture at that point and rewatch only the part you need.
What you get
Every lecture summary has
- A title inferred from the content.
- A one-sentence summary of the lecture's main point.
- 3–7 key takeaways, each linked to its moment in the video when the captions carry timing.
- 3–5 topic tags, handy for sorting notes by course.

When not to bother
Math-heavy lectures lose the most: equations written on a board never make it into the captions, so a summary captures what was said, not what was drawn. For those, use the timestamps to jump to the derivations and watch them.

FAQ
Common questions
- How much does it cost to summarize a lecture?
- One credit for a lecture up to an hour, three credits up to three hours, then one more per started hour. New accounts get 5 free credits, and packs start at $5 for 100. A lecture someone already summarized is free to read.
- Can I use it on a lecture in another language?
- Yes. Sumvid reads the lecture's own captions and writes the summary in the language you pick, so a lecture recorded in Spanish or German can be summarized in English, and vice versa.
- Does it work on every lecture?
- It needs captions. Most university and conference uploads have manual or auto-generated captions; a video with captions turned off can't be summarized, and you aren't charged for it.
- Will a summary replace watching the lecture?
- For review, deciding whether a lecture is worth your time, or finding the part you need, usually yes. For material you'll be examined on in detail, use the timestamps to rewatch the sections that matter rather than skipping the lecture.
