Get an AI summary of any YouTube video in seconds — short summary, key points, detailed breakdown or chapters. 100% Free.
The YouTube Video Summarizer reads the captions of any YouTube video and uses AI to turn them into a short summary, a list of key points, a detailed breakdown or timestamped chapters. It saves you from watching a 25-minute video just to find out whether it covers what you need — and gives creators a fast way to build chapters for their own videos.
Open the YouTube video and copy its link from the address bar or the Share button. Regular videos and Shorts that have captions work.
Choose Short Summary, Key Points, Detailed or Chapters, and set the output language.
The tool fetches the transcript and the AI writes your summary. Short videos take a few seconds; long videos are summarized in stages and take a little longer.
Copy the result to your clipboard or download it as a .txt file. Timestamps in the result are clickable and open the video at that moment.
A short paragraph with the main point and conclusion. Best when you only need to know what the video is about.
An overview sentence followed by the main takeaways as bullets. Ideal for study notes and quick reviews.
An overview, key points, a section-by-section breakdown with timestamps, and a closing takeaway. Best for long tutorials and lectures.
Timestamped chapter lines in YouTube's format. Paste them into your video description to add chapters to your own videos.
Study & Research: Get the key points of a lecture or tutorial first, then watch only the sections you need using the timestamps.
Creators: Generate chapters for your own videos in seconds, or study what a top competitor video covers before you plan yours.
Work & News: Skim long interviews, webinars, podcasts and product reviews and decide in a minute whether they are worth your time.
Foreign-Language Videos: Choose your own language as the output language and read what a video says without needing to understand the original audio.
The video has no captions. This is common for music videos, some live streams and very short clips. Try a video that shows the CC icon.
To keep the tool free for everyone, each visitor can create a limited number of new summaries per hour. Wait a few minutes and try again. Videos you already summarized are not counted.
Long videos are split into parts and summarized in stages, which can take up to two or three minutes. Keep the page open until the result appears.
Videos longer than about 30 minutes of speech are not supported right now. Try a shorter video, or a shorter clip of the same content.
Try the Detailed type for fuller coverage, and use the timestamps to check the part of the video you care about.
