Spend less time on descriptions
byline reads what's said in your YouTube videos and gives that context to Claude and ChatGPT, so they can draft the description from what you actually said.

Questions
About the YouTube description generator
Is this YouTube description generator free?
Yes. It's a free tool with no sign-up and no limit on how many times you use it.
Does it use AI?
Two ways, both on your device. The quick drafts come from templates, instantly. If your browser has a built-in AI model, or your computer can run one, it can also write descriptions with AI: the model runs on your device, so nothing you type is sent to byline or anyone else.
How do YouTube chapters work?
List timestamps in the description, starting with 00:00. YouTube needs at least three, in order, and each chapter at least 10 seconds long. Then it splits the progress bar into sections.
How long can a YouTube description be?
5,000 characters (checked November 2026). Only the first couple of lines show before “more”, so lead with what the video gives people.
