What does humanizer do?
humanizer is a Claude skill that edits text to remove the habits that make prose read as machine written, drawing on Wikipedia's Signs of AI writing guide. Claude marks the tells, strongest first: not X but Y contrasts, one-line closers, staged openers, forced groups of three, dashes, inflated significance, sales words, bold labels and chatbot leftovers, 26 patterns in all. It drafts a rewrite that keeps every supported claim and adds no new facts, checks the draft for lost or invented details, then writes a final version. Given a writing sample, it matches that voice. It returns draft and final for pasted text, or edits a named file in place.

Use it when
