About the YouTube Description Generator
YouTube Description Generator writes the description for your video. Tell it what the video is about, choose a friendly, professional or energetic tone, and the tool writes a two-sentence hook with the main topic words, a short paragraph about what viewers will learn, a chapters section with timestamp placeholders you edit, link placeholders and five hashtags. It does not invent facts, sponsors or links, so you add your own. A good description helps viewers and helps YouTube understand your video.

Write for viewers first
The description should tell a person whether the video is for them. Put the main idea at the start, in plain words, and use the words people would search. Then say what they will learn or see, so that the click feels worthwhile.
Chapters and links
Chapters make long videos easier to use. The tool writes chapter names from your description with times to edit once you know them. Add links to your channel, a playlist, your website or a product you mention, and be clear about sponsored or affiliate links.
- First line: the hook and main topic
- Next: one paragraph on what viewers get
- Chapters: starting with 00:00
- Links: related videos and your own pages
- Hashtags: three to five
Pair it with the rest
A good description works together with the title and the thumbnail. Use the YouTube Title Generator for titles, the YouTube Script Writer for the script and the YouTube Thumbnail Maker for the image.

Frequently asked questions
What should a YouTube description contain?
A strong first two lines, a summary of the video, chapters, links to related content and a few hashtags.
Why do the first lines matter?
They appear in search results and before the Show more link, so they decide whether people read on.
How do chapters work?
Put timestamps such as 00:00 at the start of lines in the description, beginning with 00:00 and with at least three chapters of 10 seconds or more. YouTube then shows chapters in the player.
How many hashtags should I use?
Three to five. YouTube shows the first three above the title, and too many can be ignored.
Can I use the same description for every video?
No. Write a fresh summary for each video. Reuse only the footer with your links.
