Works in any browser, on a phone or a computer. What you put here stays on your device.About Title CheckYouTube's rules it checks

A title can be up to 100 characters, a description up to 5,000. YouTube's API, which upload tools use, counts the description in bytes, so Title Check counts both.

Neither may contain < or >.

Tags: up to 500 characters in all. The commas count, and a tag with a space counts its quotation marks.

Hashtags: of those in the description, YouTube shows up to three by the title, the ones it judges most engaging. With more than 60, it ignores every hashtag on the video.

Chapters: the first at 00:00, at least three in order, each at least 10 seconds long.

Lists cut a long title at about 70 characters on a computer, fewer on a phone. That is an estimate, not a YouTube rule.How to use it

Paste the title, the description and the tags as they will be on YouTube.

Fix what is flagged; the counts and the preview change as you type.

Copy them back into YouTube Studio.

How long can a YouTube title be?

100 characters. Lists cut it at about 70 on a computer, so put the words that matter first.

Why do my chapters not show?

The first time must be 00:00, there must be at least three in order, and each must be at least 10 seconds long; Title Check finds the times in your description and checks all of them. Chapters also do not show when a channel has an active strike or the video may be inappropriate for some viewers, and a channel without them yet applies for access to advanced features.

Which hashtags show above my title?

YouTube picks up to three of your description's hashtags, the ones it judges most engaging. Title Check counts them, but cannot know which three.

Is what I type sent anywhere?

No. The checks run in your browser.
