ChatGPT Prompt for YouTube Summary: Use the Transcript

The most reliable ChatGPT prompt for YouTube summary notes works from the transcript, not the link. Open the video's transcript on YouTube, copy it with timestamps, and paste it into ChatGPT with what you need from the video. Then ask for a short TL;DR, timestamped key points, claims to verify, and action steps, using only what the transcript says.

Pasting the link alone is risky. ChatGPT usually cannot watch the video, so it may guess from the title or from other pages. A pasted transcript gives it the actual words and lets every point point back to a timestamp you can check.

Step 1: Copy the transcript

On YouTube in a desktop browser, open the video description and look for the option to show the transcript. A panel opens with the text and timestamps. Select it all and copy it. Many transcripts are auto generated, so expect missing punctuation and some wrong words, especially names and technical terms.

Step 2: Tell ChatGPT why you are watching

A summary is only useful if it serves a purpose. "I need three ideas for a cost review" produces very different notes than "summarize this". Also say what you already know, so the summary skips the basics.

Step 3: Ask for a transcript check first

Before summarizing, have ChatGPT flag garbled sections, gaps, or a transcript that is shorter than the video. That stops it from smoothing over a missing part with a guess.

Here is a YouTube transcript for "[title]", [length] long: [paste]. First tell me whether it looks auto generated, where it is garbled or missing, and whether it covers the full length. Do not fill any gap.

Step 4: Get a timestamped summary

I am watching this to [purpose]. I already know [prior knowledge]. Using only this transcript, give me a three sentence TL;DR, a timestamped outline, and the key points ranked by usefulness for my purpose, each with its timestamp.

Step 5: Separate claims from facts

Speakers make claims about numbers and results that apply to their own situation. Ask ChatGPT to list them as "stated by the speaker" with timestamps, so you know what to verify before repeating it.

List every factual or numerical claim in the transcript with its timestamp, labeled as stated by the speaker, and say what kind of source would confirm each one.

Step 6: Pull actions and exact quotes

Ask for action steps only if the video actually suggests them, and for a few word for word quotes with timestamps. If you plan to quote the speaker anywhere, rewatch the moment first, since auto captions can be wrong.

Use the complete summary prompt

The YouTube Transcript Summary Prompt: Timestamped Notes runs all of these steps at once: transcript check, TL;DR, timestamped outline, ranked key points, claims to verify, action steps, exact quotes, and what the video leaves out. The example summarizes a 41 minute conference talk on cutting a cloud bill for a platform team lead who needs ideas for a cost review.

Tips for long videos

• If the transcript is very long, paste it in parts and ask ChatGPT to hold the summary until you say "done".
• Ask for timestamps on every point so you can jump to anything that sounds surprising.
• For tutorials, ask for the steps as a numbered checklist with the timestamp of each step.
• Keep the summary to the length you will actually read.
