About this tool
YouTube reads your description to understand and rank your video — the first 157 characters also show in search. This generator assembles a proven structure: keyword-rich hook, timestamped chapters (which enable chapter markers in the player), your links, a subscribe CTA and hashtags, with live character counts.
How to use the YouTube Description Generator
- Enter the video topic, key moments and your links.
- Generate and fine-tune the description.
- Copy into YouTube Studio — chapters appear automatically if timestamps start at 0:00.
Frequently asked questions
How do YouTube chapters work?
List timestamps starting with 0:00, each on its own line with a label, minimum three — YouTube converts them into player chapters automatically.
How long should a description be?
Use the space: 200+ words helps ranking, but put the keyword and hook in the first 157 characters — that’s what shows in search.
