The structure mirrors how a description is actually read: the opening sentence has to earn the click from search and the "...more" fold, key points confirm the video delivers, chapters let people jump to what they came for, links go where people look for them once they're convinced, the subscribe line sits where a satisfied viewer scrolls to, and hashtags come last because YouTube reads them anywhere but viewers don't need to. Use the Title Generator and Tag Generator to build the rest of the metadata from the same topic.
YouTube Description Generator
Fill in what your video covers and get a properly structured description — hook line, key points, clickable chapters, links, subscribe line, and hashtags — in the order that reads well and helps search.
Your video
The first 150 characters are all that shows before "...more".
Three or more, starting at 0:00, become clickable chapters.

Why this order
Frequently asked questions
Is this AI-written?
No. You write the substance — what the video is about, the key points, the links — and this tool assembles it into the structure that works: hook line first, then points, chapters, links, a subscribe line, and hashtags last. Your words stay your words, nothing is sent to a server, and the same inputs always produce the same description.
Why does the first line matter so much?
Only about the first 150 characters show on the watch page before the "...more" fold, and that opening is also the part search and suggested-video systems weigh most. It should say plainly what the video delivers and include the main keyword — the tool warns you if the opening line doesn't share a word with your title.
How do timestamps become chapters?
YouTube turns a list of timestamps into clickable chapters on the player automatically when three conditions are met: there are at least three, the first is 0:00, and each chapter is at least 10 seconds long. Write them one per line as "0:00 Intro" — the tool keeps only the lines that start with a valid time and warns if the list won't qualify.
How long should a description be?
The limit is 5,000 characters, but nobody reads a wall of text. A strong opening line, four to six key points, chapters, and your links is usually 600–1,200 characters — enough to give search engines and viewers real context without padding. Repeating your keyword over and over doesn't help and can look like spam.
Should I put my hashtags in the description or the title?
The end of the description is the standard place. YouTube shows the first three from the description above your title unless the title itself contains hashtags. The Hashtag Generator on this site can build the list from your topic if you don't have one yet.
