AI text humanizer and detector
StealthWriter is a web-based AI text humanizer and detector that rewrites AI-generated or AI-assisted content so it reads more naturally. The product is positioned for writers who want clearer phrasing, smoother flow, and a more human tone without manually editing every line.
It combines rewrite controls with a built-in AI detector, so you can check text before and after humanizing it in the same workflow. The site also says the tool offers sentence-level highlighting, alternate rewrite choices, and multiple rewrite levels, with support for use in a browser across desktop, tablet, and mobile.

AI detector
Scan text before and after rewriting to see how likely it is to be flagged as AI-generated, with a built-in detector and score display.
Deep scan and sentence tuning
Review text at the sentence level with color-coded highlights, then choose from alternate phrasings when you want finer control over the output.
Human-style output
See how the text reads in practice with a focus on natural tone, rhythm, and flow rather than only word substitution.
