YouTube Shorts Caption Generator

The Shorts player shows one line of the title, about 40 characters, and no description. So the hook goes in the title’s first 40 characters, and the description and hashtags sit behind the Description panel.

How it works

01Say what the post is aboutA line of text, or switch to Image mode, drop a photo and let it read the mood, colours and setting.

02Pick platform, tone and languageInstagram, TikTok, YouTube Shorts or YouTube. 19 tones. 12 languages, each written in its own voice rather than translated.

03Get three takes, check the fold, copyThree genuinely different angles. On Instagram the hook is measured in the app’s real typography where it gets cut, one line on a Reel and up to two on a photo post, so you know it survives.

Shorts rules, built in

TitleUp to 100 characters, the hook in the first 40The Shorts player shows one line of the title, about 40 characters, then “…”. The hook goes there and no hashtag does; the rest of the title can carry more search words.

SearchThe search phrase early in the titleYouTube says its search looks at how well a video’s title, description and content match what someone typed. The phrase goes where the player shows it, and again in the description.

DescriptionNot shown in the playerViewers open it from the Description panel. Its first line carries the search words, said naturally, and the hashtags go at its end.

HashtagsTwo or threeAt the end of the description. In the Shorts player hashtags only show if they are in the title, where they use up the visible line.

YouTube Shorts questions

Do the title and description matter for a Short?

Yes. YouTube says its search looks at how well a video’s title, description and content match what someone searched for. The Shorts player shows only one line of the title, so the hook and the search phrase go in its first 40 characters.

How many hashtags for a Short?

Two or three. In the Shorts player they only show if they are in the title, where they use up the visible line, so they go at the end of the description. YouTube ignores all hashtags on a video that has more than 60.

What about full-length YouTube videos?

Use the YouTube page instead. It writes five title angles, a description with the first 150 characters set for search, and keywords.
