AI YouTube Title & Description Generator

Free AI YouTube Title and Description Generator

Describe your video in one line and get the whole package: five title options, a description written for search, chapters with timestamps, and tags sorted into tiers. Then check it against the limits that actually decide what a viewer sees — the 60-character title cut-off in search results, the “…more” fold on the watch page, YouTube's 500-character tag field, and the rules chapters have to follow before YouTube will render them at all.

How the title score works

The score is calculated in your browser, not by the model, so it is consistent and every point is explained. Press why on any title to see the breakdown. It looks at:

• Length — enough to say something, short enough to survive the 60-character cut-off, and inside the 100-character hard limit.
• Keyword placement — present, and within the first 30 characters where it carries weight.
• A specific number — counts, years and figures read as concrete rather than vague.
• A bracketed qualifier — something like (Full Guide) adds context without spending the headline.
• Curiosity and stakes — wording that gives a viewer a reason to need to know.
• Restraint — capitals and exclamation marks are penalised past one or two, as is repeating the same word.

Being straight about this: it rewards patterns that are widely associated with better click-through. It is a checklist, not a forecast. A high score will not rescue a video nobody wants, and a thumbnail usually matters more than either.

The truncation meter

YouTube allows 100 characters in a title, but search results and browse rows cut it off around 60, and mobile often shows less again. Anything past the marker is struck through so you can see what a viewer scanning results will never read. Front-load the part that earns the click.

Chapter rules YouTube enforces

Chapters only appear if the list satisfies all three conditions: the first timestamp is 0:00, there are at least three of them in ascending order, and each one runs for at least ten seconds. Break any of those and your timestamps quietly render as ordinary text. This tool checks all three, and the Fix the timings button repairs a list that has drifted.

How to Use

1. Describe the video in a line. Add a target keyword, an audience and the length if you know them.
2. Press Generate, then read the five titles best-first and press why on any score you want explained.
3. Edit a title straight in the list — the score and the truncation meter update as you type.
4. Check the watch-page preview to see where your description folds, and move anything important above it.
5. Review the chapters and tags, then copy each piece into YouTube Studio.

Please read what it writes

The text comes from a language model, which means it can be confidently wrong. It does not know your video — only your one-line description of it — so check that the chapters match what you actually cover, that no title promises something the video does not deliver, and that any figure it mentions is real. Packaging that oversells is the fastest way to lose an audience, whatever it scores here.

Privacy and Security

Your idea is sent to our server and on to the AI model purely to generate the text, and is not stored. All the scoring, the truncation meter, the chapter checks and the tag budget run in your browser. The free tier is metered per browser with a cookie — no account needed.
