How to turn a lecture or course video into study notes

Notes are for recalling, not for collecting. A summary can save you the first hour of work on a lecture, but if you only copy it you will have a tidy file and little memory of the lesson. The workflow below uses the summary as a draft and spends your time on the part that makes you learn.

Step 1: get a detailed summary first

Paste the lecture link into getbrief and choose the detailed length if you have Pro or a credit pack. Detailed briefs keep more definitions, examples and numbers per section than the normal length. For a full course, the “for AI” mode reads the entire transcript in chunks, so nothing after the first three hours is lost.

Step 2: rewrite the key points in your own words

Read one section of the brief, close it, and write the idea from memory. Then compare. This is the step that does the learning. The summary only provides a reliable list of what the lecture covered.

Step 3: turn the gaps into questions

Look at two places:

• Open questions at the end of the brief lists what the lecture claims without support or leaves unanswered. Each line is a question to look up or ask your teacher.
• Any definition that the lecturer skipped quickly. With Pro or credits, Ask the video answers a question from the transcript, for example "How does the speaker define this term?".

Step 4: check formulas, names and numbers

Spoken mathematics, chemical names and proper nouns are where automatic captions go wrong. If a formula or a date matters for an exam, open the timestamp next to it (on YouTube) and check it against the video or your course material. Never take a figure from a summary into an exam without checking it.

Step 5: keep the notes in Markdown with the source

Copy the brief as Markdown and paste it into the app you use for studying. The title and source link are included, and timestamps stay links back to the exact second. With an account, add a tag per course so your history stays searchable. More on this in YouTube to notes.

A realistic routine for a semester

1. Before the lecture, read the summary of the previous one to warm up.
2. After the lecture, produce the brief, then rewrite the key points from memory.
3. Once a week, take the open questions and answer them.
4. Before an exam, reread your rewritten notes first, and the briefs only to fill holes.

Limits to keep in mind

A summary reads what is said. Slides, diagrams and code shown on screen are invisible to it. If a lecture relies on them, use the brief as a map of the structure and take the visuals from the course material. For more on where errors come from, read how accurate AI video summaries are.
