Common questions
Is the YouTube description generator free?
Yes. A few videos a day are free with no account, and signing in with Google raises the limit.
Why generate from the transcript?
A description written from what you actually say matches the words people search for and what the video delivers, which helps search and keeps viewers watching.
How long should a YouTube description be?
YouTube allows 5,000 characters, but the first 150 or so show in search and above the fold. The generated description puts the hook there.
Do YouTube tags still matter?
Less than titles, descriptions, and thumbnails. YouTube says tags mostly help with commonly misspelled terms. The generator keeps them under the 500-character limit.
Does it work for videos in other languages?
Yes. Everything is written in the language of the video's captions.
Can I use it before my video is public?
The tool reads public captions, so the video must be public or unlisted. Unlisted works well for prepping before release.
