YouTube Description Generator
Summarise the video and you get two full descriptions: a first 157 characters written for search results, a chapters block with timestamps to fill in, a links section and three hashtags. YouTube descriptions support *bold* and _italic_ markup, and timestamps typed as 0:00 become chapters automatically.
Results come from Claude, tuned per platform. Edit them: the best version is the one that sounds like you. We do not store what you type.
Anatomy of a good description
- First 157 characters: what the video is and who it is for, with the keyword: this is the search snippet.
- Chapters: 0:00 Intro, 1:20 Setup… YouTube turns these into a chapter bar.
- Links: gear, downloads, newsletter, socials. Use UTM links to see what people click.
- Hashtags: up to three show above the title; more than 15 and all are ignored.
