Reads YouTube subtitles out loud with synthetic voices in many languages, so you can listen to a video instead of reading captions.

Adds a summary of a YouTube video's main points next to the player so viewers can decide quickly whether the full video is worth watching.
AI Summary for YouTube places a summary of a video's key points beside the player shortly after it opens. It is meant for viewers of tutorials, news, interviews and lectures who want to judge whether a video is relevant before watching all of it.
Open any YouTube video and wait a few seconds for the summary panel to appear next to the player; use the copy button to take the transcript.
Summaries rely on the video's transcript, so videos without captions or with poor audio may give weaker results.
