What AI detectors actually measure
Tools like GPTZero, Turnitin, Originality.ai, Copyleaks and ZeroGPT estimate how predictable each word is (perplexity) and how much that predictability varies across sentences (burstiness). Machine text scores low on both: every word is a likely choice and every sentence has a similar shape.
People write with more variety. We use an unexpected word, follow a long sentence with a short one, and leave small irregularities. Wrinklewrite rewrites your text to restore that variation rather than hiding words behind synonyms or invisible characters, which detectors increasingly catch.
Use it responsibly
No humanizer can promise a particular score on every detector every time, and detectors change often. Treat Wrinklewrite as a writing tool: use it to make AI-assisted drafts read like you, then review and edit the result. If your school or employer has rules about AI assistance, follow them.
