The first two lines of a description appear above the fold on most devices. That space should finish the title’s promise, include a natural keyword phrase, and give a reason to keep reading. Everything else — credits, affiliate links, chapter lists, hashtags — belongs below.
This generator builds a structured description: hook line, 60–90 word topic paragraph, optional chapter block, CTA, and a clean link stack. You edit the facts. The structure stops you from pasting a wall of social URLs above the actual summary.
How to use this tool
- Enter title, niche, key talking points, and any URLs.
- Generate the description and rewrite the first line in your voice.
- Paste chapter times from the chapter generator if you have them.
- Add legally required disclosures before you copy to YouTube Studio.
Why the first 150 characters matter
Mobile clients truncate aggressively. If your first line is “Merch drop Friday!!!” and the video is a 20-minute lighting tutorial, you have wasted the only description real estate searchers see. Lead with the tutorial outcome, then merch.
Chapters, links, and hashtags in the right order
Place timestamps near the top if the video is a dense tutorial. Place affiliate disclosures immediately next to the links they cover. Limit hashtags — three topical tags beat twenty generic ones. YouTube has used hashtags as browsing surfaces; stuffing them looks desperate and can look spammy.
Professional notes
- Put a spoken-word phrase from the video into the paragraph — it supports captions and search.
- Keep one primary URL early if you need clicks; bury the full social stack.
