LLM-notebook: turn a YouTube video into material you can question

For a lot of us, YouTube is the classroom. From linear algebra to programming basics, whole courses are sitting there in the open, and many of them are very good.

But video is an awkward thing to study from:

• It is hard to find your way back. To return to the point the instructor made ten minutes ago, you drag the scrubber and hope your memory lands on it.
• It is hard to ask. When a sentence does not land, there is nothing to ask; and the comments are answering someone else's question, not yours.
• It is hard to extract. To keep a passage, you type it out by hand while the video plays on.

So a lecture often ends with low efficiency and no real grip on the material — just a vague feeling of having followed it.

Turn a YouTube video into material you can question

To make video work better for studying, LLM-notebook takes one approach: pair it with AI so a video becomes something you can interact with.

Open one of these materials and you get three things:

• On top, the video player; the video plays there as usual.
• Under it, the video's subtitles — the raw material the AI reads the video from.
• On the right, the AI chat: ask whenever something is unclear. Answers cite the subtitle text, and each citation jumps to that moment in the video.

So the things that used to be awkward now have an answer:

• Want to go back to one sentence? Click its timestamp and the video jumps there — no more scrubbing and guessing.
• Did not follow a paragraph? Select that subtitle and ask about it; the answer points back to the original wording.
• Want to keep the important parts? Turn the subtitles into your own notes, instead of typing while you watch.

How to use it

1. Go to Material Library → New material → Website / URL, paste the YouTube link, then Confirm import.
2. When parsing finishes, the workspace shows the player with the subtitles underneath.
3. While watching:
   • Ask about the video in the AI panel on the right;
   • or select a passage in the subtitles and ask about that passage specifically.
4. Answers mark the wording they rely on: click the [N] in an answer and it jumps back to the cited paragraph and highlights it.

A few situations students actually run into

The moment	What to do
A segment you have replayed several times and still do not follow	Select those subtitles and ask "what is this part actually saying?"
Something worth keeping while you watch	Turn the subtitles into your own note instead of retyping them
You have finished a course and want to review	Ask the whole transcript: "what are the key exam points in this course?"
You want to check one concept	@ this material and let it explain using the video's own wording
You only want a quick pass first	Ask for the subtitles to be organized into an outline

Whatever you ask, the answer stays traceable: conclusions point back to specific paragraphs in the subtitles, not to a general impression of the model.
