AI YouTube Description Generator

Most descriptions fail in the first two lines — the only part visible before '…more'. This generator writes the description the way YouTube rewards: a hook in the opening lines, a compact summary of what the viewer will learn with your keywords woven in naturally, a plain call to action, and a closing line of hashtags. One deliberate limit: it never invents links, sponsors, discount codes or timestamps, because fake details in a description are a trust problem, not a shortcut. You paste the result into Studio and add your own real links where they belong.

This tool is powered by AI running on a free service tier, so a generation can occasionally take a little longer or ask you to retry at busy times. Your input is sent only to produce your result — it is not stored.

How to use this tool

  1. Enter your video title or topic.
  2. Optionally add the keywords you want woven in naturally.
  3. Click Generate description.
  4. Copy it into YouTube Studio, then add your own links and timestamps — the tool never invents those for you.

Worked example

For a video called “5 Indoor Tomato Mistakes Beginners Make”, the generator writes a two-sentence hook, a short paragraph on what the viewer will learn, a subscribe call to action, and three hashtags to close — ready to paste, with spaces left for your real links.

Frequently asked questions

Where do my links and timestamps go?

Add them yourself after pasting — the generator leaves the structure ready but never invents a URL, an affiliate code or a chapter time it cannot know. Put links right after the summary and chapters before the hashtags.

How long should a YouTube description be?

Long enough to say what the video covers and for whom — the 150–250 words this tool writes is the practical sweet spot for most videos. The first two sentences matter most; the rest supports search and the curious viewer.

Should my main keyword be in the description?

Yes, once, naturally, ideally in the first two lines — which is why the keywords box exists. Repeating it ten times reads as spam and helps nothing; YouTube weighs the opening lines and overall topic match.

Can I use one description for a whole series?

Use the generator per video and keep your channel boilerplate (socials, contact) as a saved block you append in Studio. A shared template with an identical middle is fine; an identical whole description on different videos is not.

Does it add hashtags automatically?

Three relevant hashtags close the description, which is the number YouTube displays above your title when they are in the description. More than that dilutes which three get shown.
