Best AI Detectors & Humanizers
Tools are ranked by user rating. The ones we have reviewed also carry our own score out of 10.
HumanizeAI is a lightweight tool that rewrites AI-generated text to sound more natural, with a free tier, a Pro mode and a written 30-day money-back guarantee. Its claims about beating detectors come from its own pages, and the site itself tells users to proofread. Use it as an editing aid, and follow your school or workplace rules on AI.
GPTZero is an established AI text detector aimed mainly at educators and writers, with a free scanner, writing replay and plagiarism checks. Its accuracy numbers come from its own pages, and the public pricing page shows no plan prices. It looks credible on security, but treat any detector score as a signal, not proof.
GPTHuman is a rewriting tool that aims to make AI-generated text read as human and pass AI detectors, with a built-in detector and an API. Plans run from a free trial to $49 /month, but its detector-bypass promises are the company's own claims and may conflict with school or publisher rules.
Originality.ai is an AI detector and plagiarism checker used by publishers, agencies and schools. Its own terms say results are probabilistic and can produce false positives, so treat scores as a signal rather than proof.
Quetext bundles a plagiarism checker, AI detector, humanizer, summarizer and paraphrasing tool at paid prices starting from $14.99 per month. The privacy policy describes using data for AI training, and the pages we read do not state a refund policy.
