What to watch out for
The AI humanization feature is meant to soften stiff text, but using it to disguise AI-generated work as your own may violate school or platform rules, and any consequence falls on the user. Detection scores are a reference rather than a final judgment about who wrote something, and the free detector and checker access can change. Paid plans are billed annually, so confirm current terms before subscribing. Name and archive exported files consistently so you can find and reuse them, and keep a backup copy of key data. When quality matters, export a small draft first to confirm the result before producing the final file.
