What AI Undetect does

AI Undetect is a web-based AI rewriter and detection-removal tool that helps users rewrite AI-generated text into more human-like copy. The homepage positions it as a freemium product with a detector-check step, a manual rewriting flow, and an Auto-Perfect mode for premium users.

The product is aimed at people who want to review AI text against detector outputs and then reword the text without changing its overall meaning. The site also says it supports multiple languages and offers different rewrite styles, so it can be used for short-form and long-form text adaptation rather than a single narrow workflow.

Key capabilities

AI detection check before rewriting

The homepage presents a detector-check step followed by rewriting, so users can review how text performs before humanizing it.

Human-like rewording

Users can paste AI-generated text and convert it into human-like text while keeping the original meaning, according to the site copy.

Manual and Auto-Perfect workflows

The page offers Manual mode and a premium Auto-Perfect mode, with Auto-Perfect described as continuously refining output until it is ready.

Style-based rewriting options

The site lists multiple rewrite styles such as General, Informal, Expand, Academic, Blog, Simplify, Formal, and History.

Multi-language support

The homepage says the product supports 20+ languages, with language switching shown for several major languages.

Account-based subscription plans

Subscription plans on the homepage include word limits, history access, and support for auto-perfect mode, indicating account-based usage controls.
