Free and Pro

Without an account: AI tools need a free account.
Free account: 5 AI runs per day, videos up to 60 minutes. Neutral tone.
Pro: 30 AI runs per hour, videos up to 120 minutes. Four tones.

Pro adds a choice of tone. Both plans get one description per run.

What is checked

Every sentence in the description is backed by a quote from the transcript and is dropped if the quote is missing, if it names a person or product that is not in the video, or if it is written in another language. Tags and hashtags may only use words the video, its title or its channel contain. The result is cut to YouTube's 5,000-character description limit, keeping your call to action.

Limits you should know

AI tools need a free account. A free account gets 5 runs for videos up to 60 minutes. Pro allows 30 runs per hour for videos up to 120 minutes. A run that fails or finds nothing reliable is not counted.
Results are private to you. They are not added to the public transcript library and not listed in the sitemap.
AI output can contain mistakes. Every title and sentence is checked against the transcript and dropped if it is not supported, but you should still read the result before you publish it.
The tool never adds links or promises. Anything beyond the video's content, such as links, comes from the call to action you type.

FAQ

How long can a YouTube description be?

YouTube's Help page gives a limit of 5,000 characters. The tool shows the length of the result.

Does it include my links?

Only the call to action you type. It is added as written.

Does it write chapters too?

Chapters come from the chapter generator. If you made them in the same page, you can include them without another AI run.

Are the tags guaranteed to help my video rank?

No. They are search phrases taken from words used in the video. No tool can promise results.

Is my result public?

No. It is private to you and not added to the public library.
