AI YouTube Description Generator

A description written for the 150 characters shown above the fold — with chapter timestamps checked against the rules YouTube enforces silently.

Your video

Chapters are checked against YouTube's actual rules

Chapters fail silently: get one rule wrong and they simply do not appear, with no error to tell you why. The first must be 00:00, there must be at least three, and they must ascend — all three are verified below before you paste anything.

Why use it

Built to be genuinely useful

Chapters verified, not guessed

First marker at 00:00, at least three, ascending. Break one and YouTube disables chapters without telling you.

Above the fold shown separately

Only about 150 characters appear before “…more”, and that is also what search shows.

Three hashtags, not thirty

YouTube displays only the first three above the title. The rest are noise.

Free, no sign-up

Paste the result straight into YouTube Studio.

How it works

Three steps

  1. 1

    Describe the video and roughly how long it runs.

  2. 2

    Choose whether you want chapter timestamps and a links section.

  3. 3

    Check the chapter panel — every rule must pass before chapters will appear — then copy.

Why chapters fail silently

YouTube chapters have three requirements and no error message. The first timestamp must be exactly 00:00, there must be at least three timestamps in total, and they must run in ascending order. Break any one and chapters simply do not appear — no warning in Studio, no note on the video, nothing to tell you why.

This is why so many creators conclude the feature is unreliable. It is not unreliable; it is strict and quiet. The most common failure by far is starting at 00:15 or 01:00 because the intro runs first, which is a perfectly reasonable thing to do and disables the whole list.

The tool checks all three rules against the description it produced and reports each one separately, so you find out here rather than by refreshing the watch page and wondering.

The first 150 characters do most of the work

YouTube shows roughly the first 150 characters of a description before collapsing the rest behind “…more”, and that same opening is what appears under your video in search results and, often, in Google's results too. Everything after it is read only by people who were already interested enough to expand it.

So the opening should be a sentence that summarises the video for someone deciding whether to watch, not a keyword list and not a greeting. "Subscribe for more!" occupying that space is a wasted opportunity repeated across an entire channel.

Below the fold, two or three short paragraphs on what the video covers and who it is for do real work — for viewers scanning before committing, and for YouTube's understanding of the topic. Links, chapters and credits belong under that, where their formatting does not interrupt the reading.
