AI detectors analyze statistical patterns—sentence length variance, word choice bursts, perplexity—that differ between typical human drafts and homogeneous model output.
They do not "read minds"; they estimate probability. That means rewriting for natural rhythm, specificity, and personal voice usually improves outcomes more than synonyms alone.
Use tools ethically: revise your own ideas, cite sources, and follow your institution's policies. Humanization helps polish drafts you already understand—it is not a substitute for learning.
