Does this tool rewrite my Shorts caption with AI?
No. The first version stays deterministic and client-side. It reorganizes the draft you already wrote instead of generating a new angle for you.

FAQ
Questions about Shorts caption cleanup
What does it clean up automatically?
It can regroup the hook, supporting lines, CTA, blank-line spacing, and hashtag placement so the caption is easier to scan and reuse.
Should a Shorts caption always include a CTA?
Not always, but many Shorts workflows benefit from a clear next step such as follow, comment, save, or watch the full video. The tool warns when it cannot find one.
