YouTube Description Generator
Write a search-friendly YouTube video description in seconds.
The description box is where most creators run out of steam after a long edit. This free AI YouTube description generator turns a few sentences about your video into a structured description: a clear opening, supporting detail, a list of what the video covers, a subscribe line and a few hashtags.
The opening two lines carry your main keyword, because that's the part viewers see before they expand the description. Pick a tone that matches the way you talk on camera and the rest follows suit. The draft deliberately leaves out timestamps, links and sponsor mentions, since only you know those. Add them before you publish. You can preview the visible part with the YouTube title and description checker.
It's free with no signup, with a few generations a day if you're not logged in. Round out the upload with the YouTube title generator and the tag generator, then publish on schedule with PostJay's YouTube scheduler.
Frequently asked questions
What does the generated description include?
An opening two lines that sum up the video with its main keyword, a short paragraph of detail, an 'In this video' list of key points, a line asking people to subscribe, and three hashtags at the end. It's a solid structure you can paste in and then personalise.
Why do the first lines of a description matter so much?
Only the start of the description shows before viewers tap 'more', and it can also appear in search results. Those lines should say plainly what the video is about. Check how yours will look with the YouTube title length checker, which previews the visible part.
Will it add timestamps and links?
No, on purpose. The generator doesn't know your video's chapters, your affiliate links or your social handles, and made-up ones would be worse than none. Add your real chapters, links and credits after you paste the description in.
How long can a YouTube description be?
Up to 5,000 characters. The generator keeps drafts much shorter than that so you have room to add timestamps, links and credits. A live counter shows where the draft sits against the 5,000 limit.
