YouTube Video Summarizer
Paste a YouTube link. We fetch the video's captions, and AI writes the gist, 5 to 8 key points and a section-by-section outline with timestamps. Free, no signup, with a daily limit.
This is a long video: the summary was written from a condensed transcript, so smaller details may be missing.
Made by AI from the video transcript. It can miss or misread things — check names, numbers and quotes against the video. The summary is kept in this browser so you can come back to it.

How the YouTube Summarizer Works
Two steps, the transcript and then the summary. Here is what happens in each.
The summary is written from the video’s transcript, and the transcript comes from its captions: the ones the creator uploaded or the ones YouTube generates automatically. We clean up their punctuation and save the result as a transcript page in the SozAI library, so the next person who asks for the same video gets it at once.
A video with no captions at all cannot be summarized here. If you have its audio file, the SozAI app can transcribe and summarize it.
Captions First
Every summary has the same shape. In short: one or two sentences on what the video is about and where it lands. Key points: 5 to 8 concrete takeaways with the names, numbers and steps that matter. Section by section: 3 to 8 consecutive parts with short titles that together cover the whole video.
There is no length setting. The shape stays the same, so a short tutorial and a long lecture are equally quick to scan.
Three Layers in One Summary
When the captions carry timing, each section starts with the moment it begins in the video. The time is checked against the transcript: a start the transcript does not contain, or one that runs backwards, is dropped instead of shown.
Click a timestamp to open the video at that point and hear the original before you quote it.
Timestamps You Can Check
Very long transcripts are condensed before the AI reads them, so the summary still covers the whole video. When that happens, the page says so, because smaller details may be missing.
The summary is written by free AI models and usually takes 10 to 40 seconds once the transcript is ready. A video we have not read before takes longer, because its captions are fetched first.

Professional Use Cases
Where a short written summary saves real time
Get the structure of a lecture or conference talk before you decide to watch it, and use the timestamps to jump to the part you need for your notes.
From the result, turn the same video into flashcards or a quiz with one click.
Read the main points of a keynote, webinar recording or product demo published on YouTube, and share the summary with colleagues as text.
For your own meetings and calls, the SozAI app records them and writes the summary for you.
See what a popular video in your niche actually covers, section by section, before you plan your own take on the topic.
Download the summary as Markdown to drop it into your notes or a draft.
Check whether a long tutorial, documentary or interview answers your question before you give it an hour. The key points tell you what it covers; the timestamps take you to the part worth watching.
Send your team a short written briefing on an industry video instead of asking everyone to watch it. The copy button puts the whole summary on your clipboard.
Find where a statement was made in a long interview or press conference, then open the video at that timestamp and check the exact words. The summary points you to the place; a quote should always come from the video itself.
How It Works
From a YouTube link to a written summary
Paste a link to a public video: a regular watch link, a youtu.be link, a Short or a live recording. The video needs captions, uploaded or automatic.
If the video is already in our library, its transcript is ready at once. A new video is read first, and you see the progress on the page.
The summary usually appears within a minute. Copy it, download it as .md or .txt, open the full transcript, or make flashcards and a quiz from the same video.
What Happens to the Video and the Summary
A plain account of the data this tool touches
We read the captions of public YouTube videos. You do not sign in, and nothing is taken from your YouTube or Google account.
A video read here for the first time gets a public transcript page in the SozAI library, like every transcript made with the SozAI YouTube transcript tool.
Your last summaries are stored in this browser, so reopening a video does not use up your daily limit. Clearing the site's data removes them.
There is no account. A random device ID and a Cloudflare check keep the free daily limits fair and stop bots.
Summaries are written by free AI models from the transcript. They can miss or misread things, so check names, numbers and quotes against the video.

Limits, languages and accuracy, answered plainly
Yes, and there is no signup. To keep it free, there are daily limits per device and per network. When you reach one, the page tells you, and you can continue the next day.
Public YouTube videos that have captions, either uploaded by the creator or generated automatically by YouTube. Regular links, youtu.be links, Shorts and live recordings all work. A video without captions cannot be summarized here; if you have its audio file, the SozAI app can transcribe and summarize it.
Once the transcript is ready, the summary usually takes 10 to 40 seconds. A video already in our library has its transcript ready at once; a new one is read first, and the page shows the progress.
Usually the language of the video, which is detected from its transcript. A video in Spanish gets a Spanish summary.
They are written by free AI models from the video's captions, so they inherit any caption mistakes and can miss or misread points. Very long videos are condensed first, and the page warns you when that happens. Use the timestamps to check anything you plan to quote or rely on.
