YouTube Video Summarizer: AI Summary, Chapters, Key Points

Turn any YouTube video into a summary you can read in one minute:

• TL;DR: the video in one sentence.
• Summary: one short paragraph.
• Key points: the most useful points, most important first.
• Chapters with timestamps: a title and one sentence for each part, and a link that opens the video at that moment.
• Quotes: short, striking sentences from the video, each with its time and link.
• Topics: the keywords and names the video is about.
• Your own question (optional): ask the same question about every video, for example "Which products are mentioned?". The answer comes from what is said in the video.

Why this one

• Checked, not made up. Chapter times come from the transcript and never point past the end of the video. A quote is kept only when its words really are in the transcript, and its time is taken from the transcript, not from the AI.
• Any language. Summarize a Spanish video in English, or an English video in German. Quotes stay in the words the speaker used.
• Long videos too. A 3-hour podcast gets chapters spread over the whole 3 hours.
• One price, all included. The transcript, the AI and the proxy are in the price. You do not need your own OpenAI key.
• You pay only for summaries. Videos with no captions, private or removed videos, and failed summaries are listed with the reason and are not charged.
• Pairs with the YouTube Scraper: list a channel or a search there, then send the links here.

In the same run, an 82-minute podcast got 15 chapters and 5 checked quotes, and a Spanish cooking video was summarized in English with its quotes kept in Spanish. All 3 videos took 13 seconds.

Pricing

Pay per video summarized. Videos with no captions and errors are free.

Notes

• The summary is made from the video's captions (written by a person, or YouTube's automatic ones). A video with no captions at all cannot be summarized and is not charged.
• Automatic captions can misspell names. Quotes keep the caption's words exactly as they are.
• Transcripts longer than about 6 hours are cut at that point, and the row says "truncated": true.
