    Why One Tool Works Against All Detectors

    Despite their different brands and marketing, all AI detectors fundamentally analyze the same linguistic patterns:

    1. Perplexity — How predictable is the word choice?
    2. Burstiness — How varied is the sentence structure?
    3. Vocabulary patterns — Are there AI-typical phrases?
    4. Coherence — Is the structure suspiciously perfect?

    AI Free Text Pro's humanizer addresses ALL of these patterns simultaneously. By restructuring the fundamental linguistic characteristics of AI text, humanized content passes any detector that uses these analysis methods — which is all of them.
