Cons

AI Detection Results Are Not Guaranteed: Humanized content may still be detected by AI detection tools. Rephrasy states that it cannot guarantee content will bypass every AI detector.
Output Quality Varies: Some content may require manual editing to improve clarity, grammar, or preserve the original meaning, particularly for technical or highly specialized writing.
Advanced Features Require a Paid Plan: Features such as custom writing styles, higher usage limits, API access, and additional plagiarism credits are only available with paid subscriptions.
Best Results Still Require Proofreading: Although the humanizer can improve readability, reviewing the output before publishing is recommended to ensure accuracy and natural wording.
