YouTube video summarizer

A YouTube video summarizer reads a video and tells you what it says in a few minutes of reading. Instead of watching an hour-long talk, you get the main argument, the key points in order and the moments worth watching, each tied to a timestamp so you can check the source.

A summary is only as good as what it reads. Summaries built from the title and description miss most of the content. A useful summarizer works from the full transcript, so it can quote the speaker exactly and point you to where each idea appears. It should also tell you when a point is the speaker's opinion rather than a fact, so you know what to check before you repeat it.

Endless reads the video's details, such as title, channel, length and description, and its transcript. Then the agent writes a summary with key points, timestamps and direct quotes. You can ask follow-up questions in the same chat, like what the speaker said about pricing. The summary stays in the chat, so you can come back to it later.
