Opening sentences
The first lines of the transcript and an opening excerpt — usually where the speaker says what the video is about.
Auto-generated chapters
Chapter timestamps in YouTube’s own format, starting at 0:00, ready to copy into a description or skim as an outline.
Draft description and tags
A draft video description and suggested tags and hashtags built from the transcript, each with its own copy button.
Runtime and word count
See how long the video runs and how many words are spoken, which tells you roughly how long it would take to read instead.

How to summarize a YouTube video
There are two ways to get a summary of a YouTube video here, depending on how much detail you need:
- Copy the video link from the address bar or the Share button. Watch, youtu.be, Shorts and live links all work.
- Paste it into the box above and press Get Free Summary. In a few seconds you get the overview: key terms, opening sentences, chapters, a draft description and tags.
- For a written summary in your own words, open the full transcript, press Copy, then paste it into ChatGPT, Claude or Gemini together with one of the prompts on this page.
What this YouTube summary generator gives you (and what it does not)
We want to be clear: the overview on this page is not written by an AI model. It is calculated directly from the video’s captions — word frequencies, the opening of the transcript, and evenly split chapter markers. That makes it instant, free and consistent, and it never invents anything the speaker did not say.
What it cannot do is rewrite the argument in fresh sentences or answer questions about it. For that you need an AI assistant, and the most reliable way to feed one a video is to give it the transcript. That is why every summary result links straight to the full transcript.
How to summarize a YouTube video with AI
Most AI chatbots cannot watch a video. When you give them only a link, some will try to fetch the page and others will simply guess from the title — which is how you end up with confident summaries of things the video never said. Giving the AI the transcript fixes that.
- Get the transcript of the video here and press Copy. Turning timestamps off gives cleaner text; leave them on if you want the summary to point to moments in the video.
- Open ChatGPT, Claude or Gemini and paste one of the prompts below.
- Paste the transcript underneath the prompt and send it. Ask follow-up questions in the same chat to go deeper on any part.
Can ChatGPT summarize a YouTube video?
Yes, as long as it has the words. ChatGPT, Claude and Gemini are very good at summarizing a YouTube video transcript, but whether they can open a link on their own depends on the version and the video. Pasting the transcript works every time, with any assistant, including free plans.
Very long videos may exceed what a single message can hold. If the AI says the text is too long, split the transcript in two, ask for a summary of each half, then ask it to combine them.
A free YouTube video summarizer with no sign-up
There is no account, no extension and no credit system. The overview works for any video that has captions, whether the creator uploaded them or YouTube generated them automatically. It works in any browser on desktop, iPhone and Android.
If a video has no captions at all, there is nothing to summarize: we read the captions YouTube publishes rather than transcribing the audio.

Frequently asked questions
How do I summarize a YouTube video for free?
Paste the link above and press Get Free Summary for an instant overview. For a written summary, copy the transcript and paste it into a free AI assistant with one of the prompts on this page.
Is this an AI YouTube video summarizer?

Can ChatGPT summarize a YouTube video from a link?
Sometimes, depending on the version and whether it can reach the video, and it may guess from the title when it cannot. Pasting the transcript is the reliable method and works on free plans too.
How do I get Gemini to summarize a YouTube video?
Copy the transcript from this site, open Gemini, paste one of the prompts above followed by the transcript, and send it.
What is a YouTube transcript summarizer?
A tool that works from the spoken text of a video rather than the video itself. Because it reads the transcript, it can only summarize what was actually said.
Can I summarize a YouTube video without subtitles?
No. We read the captions YouTube publishes, including auto-generated ones. If a video has no captions at all, there is no text to summarize.
Does it work for long videos?
Yes. Lectures and podcasts of several hours work fine for the overview. For AI summaries of very long videos, split the transcript into parts if the assistant reports it is too long.
Do I need to install an extension?
No. It is a website that works in any browser, on desktop and on phones, with nothing to install.
