YouTube Description Generator
Generate a structured YouTube description with AI — keyword hook, summary, chapter timestamps, links section and hashtags, within 5,000 chars.
About the YouTube Description Generator
A YouTube description does quiet but important work: the first lines feed search and appear under your video, chapter timestamps create the progress-bar sections viewers love, and the links section turns viewers into subscribers and customers. This free AI generator writes the whole thing in one structured draft.
Describe your video, toggle whether you want chapter timestamps and a links section, and it produces a description in the proven order: a keyword-rich hook, a summary of what viewers will learn, a Chapters block starting at 00:00 with placeholder times you adjust to your actual video, a Links block with placeholder URLs, and hashtags at the end.
A live counter tracks the 5,000-character limit. Copy the draft, replace the placeholders with your real timestamps and links, and paste it into YouTube Studio.

Frequently Asked Questions
How long can a YouTube description be?
Up to 5,000 characters — roughly 800 words. Only the first 2-3 lines show before the "...more" fold, so the generator puts the keyword-rich hook and the most important information right at the top.
How do YouTube chapters work?
Add a list of timestamps in the description where the first one is exactly 00:00, with at least three timestamps in ascending order, each followed by a title. YouTube then splits the progress bar into named sections. The generated Chapters block follows this format — just replace the placeholder times with your real ones.
Do descriptions affect YouTube SEO?
Yes — YouTube's search uses the description (especially the first lines) to understand the video's topic, and Google indexes it for video results. Mention your main keyword naturally in the first sentence or two and cover related terms in the summary; keyword-stuffing adds nothing.
How many hashtags should a YouTube description have?
Up to three hashtags from the description appear above the video title. You can include up to 15 in total (more than that and YouTube ignores all of them), but 3-5 relevant ones is the practical sweet spot the generator uses.
Is the description generator free?
Yes — free, no signup, no watermark. Your video summary is only used for generation and isn't stored.
