GPTHuman AI

About the tool

GPTHuman AI is a humanizer for writers, students and marketers who draft with ChatGPT, Claude, Gemini or another language model. You paste AI-generated text and it rewrites the wording, rhythm and sentence structure so the result reads like a person wrote it. Tones include Standard, College and PhD, modes include Balanced and Enhanced, and the site lists support for 50 or more languages. It also includes an AI detector, a paraphraser and a writer that drafts new text from a prompt. GPTHuman AI's main promise is that its output passes AI detectors such as GPTZero, Turnitin, Originality.ai and Copyleaks. If a humanized text is still flagged, GPTHuman AI rewrites it for free, and it says its models are retrained to stay ahead of detector updates. Paid plans add Shield Guard protection against AI detectors, and every plan, the free one included, removes the hidden watermark characters that ChatGPT and Claude can leave in their output. The site has a section for students' academic writing that names Turnitin directly. A developer API is available for teams that want to humanize text inside their own apps. The free plan gives a 300-word humanizing trial and limited AI detection. Starter costs $15 a month or $99 a year ($8.25/month) for 25,000 words a month, Plus costs $25 a month or $168 a year for 60,000 words, and Unlimited costs $49 a month or $312 a year. Yearly billing saves up to 45%, and all purchases are non-refundable. GPTHuman AI is run from Montréal, Canada.
