Frequently asked questions

What is the difference between TXT, JSON and CSV?
TXT is plain text to read or paste into notes. JSON keeps every line with its start and end time, for apps and AI tools. CSV opens in Excel and Google Sheets with one line per row.
Why does it say there is no transcript?
Some videos have no captions at all, and some creators turn them off. If YouTube shows a transcript on the video page, this tool can read it.
What does "auto-generated" mean?
YouTube makes these captions with speech recognition. They are usually good but can have small mistakes with names and numbers.
Does it work for private or age-restricted videos?
No. We only read public videos. Private, members-only and age-restricted videos need a YouTube login.
