YouTube 文字起こし：AI要約とチャット 作成者: Deepak

Read any YouTube video in seconds.

A 47-minute lecture, a two-hour podcast, a long tutorial: you rarely need all of it. Open the video and the full transcript is already beside the player, every line timestamped, so you can read it at your own speed and skip to what matters.

WHAT YOU CAN DO

Find the exact moment
Search the whole video for a word, then click the line and the video jumps straight there.

Get the point without watching it all
An AI summary in the length and format you pick: a short paragraph, key points, or Q&A.

Ask the video anything
Get answers drawn from what was actually said, with the timestamp so you can check.

Keep your notes
Copy the transcript or summary into Notion, Obsidian or Google Docs with the formatting intact, or download it.

Read it in your language
The transcript opens in your language when the video has it, and translates into any language YouTube offers.

MADE FOR

Students reviewing lectures, researchers working through interviews, anyone taking notes from podcasts, courses and tutorials, or looking for the one part of a long video they actually need.

HOW IT WORKS

1. Add to Firefox
2. Open any YouTube video that has captions
3. The transcript is already open beside the player
