YouTube Shorts Caption Generator

A browser tool that takes your Shorts script and writes four things you can paste straight into YouTube Studio: a title under 60 characters, a description, a list of 5 to 8 hashtags, and a 3-second on-screen hook line for the video itself.

YouTube Shorts retention is decided in the first 3 seconds, and the title pulls the click. Most creators spend more time editing the video than writing the metadata, then watch the post underperform because the title was vague. This tool gives you a click-worthy title and a description that supports it, in seconds.

Yes, 100% free. The Shorts Caption Generator is part of the Jupitrr Free Video Toolkit. We want to build quick and easy video tools that help you every step in creating content for your business.

No. The Shorts Caption Generator runs entirely in your browser, so there is nothing to install, download, or sign up for. It works on macOS, Windows, ChromeOS, and Linux as long as you can open the page.

Under 60 characters. YouTube truncates titles in the mobile feed around there, and the click-worthy lines tend to be even shorter (45 to 55 characters). The tool respects that ceiling so the title never gets cut off mid-thought.

YouTube counts at most 15 hashtags, but the first 3 are what show in the title bar. The tool returns 5 to 8, with one broad (#shorts), one niche, and the rest topic-specific. More than 8 is wasted.

A hook works when it creates a question the viewer needs the next second to answer. Short, specific, and tied to a payoff inside the first 10 seconds. Never a generic greeting.

Yes. The model uses your script as the source of truth and pulls the strongest line from your own words rather than inventing new claims. Your tone, your facts, your numbers.

Shorts metadata is title-first (YouTube ranks heavily on title), while Reels captions are conversational. If you cross-post to Instagram Reels, use the Reels Caption Generator for an Instagram-native caption. For TikTok, use the TikTok Caption Generator.

The Caption Generator writes the metadata. For the video, use the Camera Recorder, or the Teleprompter & Camera Recorder if you want to read a script naturally while filming.
