Turn a YouTube Lecture into Study Notes

Paste the link to a recorded lecture, course video or conference talk. QuickTube's AI reads the transcript and gives you a summary and key points, then a quiz to check what stuck and a chat for the parts you didn't follow. Try it without an account: you get 30 free AI generations.

How it works

  1. 1

    Paste the lecture link

    University lectures, online course videos and talks on YouTube, as long as they have captions.

  2. 2

    Read the summary

    The main ideas, key points and topics covered, as structured notes.

  3. 3

    Test yourself

    Generate a multiple-choice quiz from the lecture and read the explanation for every answer.

What you get

Structured notes

An overview, the key points, notable quotes and the topics covered, formatted with headings and bullets.

Quiz from the lecture

Multiple-choice questions on the key concepts, with explanations, to check you understood before an exam.

Ask the lecture

Chat to get a concept re-explained, a definition, or the steps of a worked example, answered from the transcript.

Searchable transcript

Search for a term to find the timestamp where it was introduced, or watch the video with the transcript alongside.

A study routine that uses it well

Watch the lecture once, then read the summary to see the structure of what you just heard. Take the quiz the same day and again before the exam. When a question trips you up, ask the chat to explain that part, or search the transcript and re-watch only that section.

A summary is a review aid, not a replacement for the lecture. Slides, diagrams and anything written on the board are not in the transcript, so the AI only knows what was said aloud.

Frequently asked questions

How do I summarize a YouTube video?

Paste the video link into QuickTube, fetch the transcript, and open the Summary tab. QuickTube's AI reads the whole transcript and returns the key points, notable quotes and topics covered, so you can decide in seconds whether the video is worth watching.

How do I make a quiz from a YouTube video?

Paste the video link into QuickTube and open the Quiz tab. The AI writes multiple-choice questions from the transcript, each with four options, the correct answer and a short explanation. You get 5 questions by default and can set up to 20 in your preferences. A quiz costs 5 credits.

How long can the video be?

There is no fixed length limit on transcripts. The summary, highlights and quiz read up to 400,000 characters of transcript, which covers most podcasts, lectures and long interviews in full. The fact checker reads the first 100,000 characters and chat up to about 116,000, roughly the first two hours of speech; anything beyond that is cut off.

Is QuickTube free?

Fetching and downloading YouTube transcripts in the QuickTube web app is free and needs no account. AI features such as summaries, highlights, quizzes and chat use credits. Visitors without an account get 30 free AI generations, and new accounts receive 400 free credits after verifying their email. More credits are available as one-time packs, with no subscription.

Does it work with videos in other languages?

Yes. QuickTube uses the captions in whatever language the video has them, preferring English when an English track exists. It does not translate them. Quizzes are written in the language of the transcript. Through the API you can ask for specific languages in order of preference.
