Summarize Any YouTube Video in Under a Minute
A 45-minute video usually has about ten minutes of things you actually need. The fastest way to find them is to read the transcript, or better, to hand the transcript to the AI assistant you already use and ask for the summary you want.
Paste the link below, copy the transcript, and drop it into ChatGPT, Claude, or Gemini with one of the prompts further down. There is nothing to sign up for and nothing to install.
The three-step version
Step one: paste the YouTube link into the box above and wait a second or two for the transcript to load. Step two: open the Prompts menu under the transcript and pick Summary or Key Takeaways; it copies the prompt with the transcript attached. If the video is short, leave timestamps on so the summary can point back to specific moments; if it is long, turn them off to keep the text compact. Step three: open your AI assistant, paste, send. The Open in ChatGPT button does the same in one click, with the transcript on your clipboard and a new chat waiting for the paste. If you would rather write your own prompt, the next section has three that work as they are.
Three prompts that get useful summaries
For a quick read: 'Summarize this transcript in three short paragraphs. Lead with the main argument, then the two or three strongest supporting points, then anything the speaker admitted was uncertain.' For a decision: 'List every recommendation the speaker makes, one per line, with the reasoning given for each. Flag any that contradict each other.' For a study or research pass: 'Give me ten key takeaways as a numbered list. Each one should be a complete sentence I could quote, and each should name the timestamp where it appears.' The timestamp version only works if you copied the transcript with timestamps on.
The transcript decides how good the summary is
Whichever assistant you use, the summary can only be as good as the text it was given. Auto-generated YouTube captions are fine for most talks and tutorials, but they drop punctuation and sometimes garble names and numbers. If a summary makes a claim that seems off, click the timestamp in the transcript here and listen to that moment. Creator-uploaded captions are close to word-perfect, and LinkTranscript uses those whenever a video has them.
Long videos: summarize in parts
Most assistants handle an hour-long transcript in one paste. For anything longer, or for a lecture series, summarize in chunks of twenty to thirty minutes and then ask for a summary of the summaries. Copying a selection is easy here: highlight the lines you want in the transcript and use Copy selection, which grabs just that passage.
What to do with the summary
Use the summary to decide whether the full thing is worth your time, to write your own notes, or to find the section you want to watch properly. If you are going to quote the speaker anywhere public, quote the transcript, not the summary, and check the timestamp first.
Frequently asked questions
How do I summarize a YouTube video with ChatGPT?+
Paste the video link above, copy the transcript, then paste it into ChatGPT with a prompt describing the summary you want. The prompts on this page are a good start.
Does LinkTranscript generate the summary itself?+
No. LinkTranscript gives you the transcript. The summary is written by whichever AI assistant you paste it into, so you stay in control of the prompt and the tool.
Is this free?+
Yes. Getting the transcript is free with no account. Your AI assistant's own free tier or subscription applies on that side.
Can I summarize a video that has no captions?+
No. If YouTube has no caption track for a video, there is no transcript to extract, and LinkTranscript will say so rather than guess.
How accurate will the summary be?+
As accurate as the captions and the prompt. Verify any specific claim by clicking its timestamp in the transcript before you rely on it.
