Can ChatGPT Summarize a YouTube Video?

Option 1: Copy the transcript manually and paste it into ChatGPT

YouTube has a built-in transcript feature for most videos. Open the video, click the three-dot menu below the description, select "Show transcript", then select all the text and copy it. Paste it into ChatGPT with a prompt like "summarize this transcript."

This works, but it has real limitations. The copied text comes with timestamps on every line — "0:23 So today we're going to talk about" — which means you're burning through tokens on noise, not content. For a 30-minute video, you can easily paste 8,000–12,000 words, and longer videos may exceed ChatGPT's context window depending on which plan you're on.

You also can't do this on mobile — YouTube's iOS and Android apps don't have a copy button in the transcript panel. And if you're on a YouTube Short, there's no transcript button at all.

1. 1

   Open the video on YouTube

   Make sure you're on desktop — this doesn't work in the YouTube mobile app.

2. 2

   Click the three-dot (…) menu below the description

   It's next to the Like/Share/Save buttons.

3. 3

   Select "Show transcript"

   A panel opens on the right with timestamped lines.

4. 4

   Select all the text and copy it

   Ctrl+A inside the panel, then Ctrl+C (or Cmd on Mac).

5. 5

   Paste into ChatGPT with a prompt

   Try: "Summarize the following transcript in bullet points: [paste here]"

Option 2: Use a browser extension

Several browser extensions can pull a YouTube transcript and feed it to ChatGPT or Claude automatically. You click a button on the video page and a summary appears. This is genuinely convenient if you watch a lot of videos.

The tradeoffs: you have to grant the extension permission to read all webpage content (that's the permission the install dialog asks for), most of the capable ones cost $8–10/month, and you're adding another login and billing relationship to manage. For occasional use, it's more overhead than it's worth.

Option 3: Use a dedicated tool — one click, no copy-paste

RunCLI's YouTube Summary tool handles the whole pipeline: you paste the URL, it fetches the transcript, and returns a structured summary with key points, timestamps, and takeaways. No account required to try; 3 credits per video.

If the video doesn't have captions — which happens with new uploads, creator-disabled subtitles, or certain content categories — it automatically falls back to AI speech transcription and summarizes from that instead. You don't have to do anything differently.

This is the fastest option if you just want the summary and don't need to tweak the prompt.

If you specifically want to use ChatGPT: the best workflow

Some people want ChatGPT because they plan to ask follow-up questions, pull specific quotes, or integrate the summary into a longer conversation. That's a legitimate reason to use it over a one-shot summary tool.

The cleanest workflow: use RunCLI's YouTube Transcript tool to get the plain text without timestamps, then paste that into ChatGPT. You get cleaner input (no timestamp noise), and you can use the full transcript for Q&A, translation, or generating your own summary format.

Here's a prompt template that works well — paste it, then add the transcript below it:

• Summarize the main topic in 2–3 sentences.
• List the 5 most important points as bullets.
• Note any concrete recommendations or action items mentioned.
