Lecture Summary: YouTube, Udemy And Coursera

Lecture Summary is a Chrome extension built for anyone who watches courses on YouTube, Udemy, or Coursera. Instead of scrubbing through hours of video to find what matters, you get concise summaries and integrated transcripts of your video lectures right where you learn.

This makes efficient learning effortless: skim the summary to decide whether a lecture is worth your time, or jump straight to the transcript to review key information without rewatching. Whether you are studying for an exam, picking up new skills, or reviewing course material, the essentials are always one glance away.

Note that the extension supports YouTube videos under 28 minutes, with transcripts not exceeding 4000 words, so your most common lectures and tutorials are fully covered.
