Use tool ↗About GPTinf
GPTinf paraphrases machine-written text, varying vocabulary, sentence length and grammatical patterns with the stated goal of defeating AI-detection classifiers. A keyword-freezing control lets you pin names, citations and brand terms so they survive the rewrite untouched, and the same account carries a detector, a grammar checker and a plagiarism checker that do not draw on the word budget. It runs as a single-purpose web app billed by monthly humanizer words, with a partial preview that works before you create an account. The site returns HTTP 403 to automated clients, so plan details here come from third-party reviews, not the vendor's page.

Pros & cons of GPTinf
This is a detector-evasion rewriter and you should judge it as exactly that. If you are a student, running coursework through it is an academic-integrity violation whether or not the detector catches you.
Pros
- word locking preserves citations, proper nouns and product names through the rewrite
- a usable trial runs without an account, so you can judge output before paying
- priced by word volume rather than per seat, which suits occasional use
- one screen, no setup, no onboarding
Cons
- independent reviews rate output as inconsistent, particularly across longer paragraphs
- detector evasion is an arms race, so what passes this month can fail next month
- no company name, team or jurisdiction disclosed anywhere on the site
- no API, so it cannot be wired into a content pipeline
Best for
- marketers loosening obviously templated AI copy before a human edit pass
- stress-testing how brittle your own organisation's AI-detection policy is
- writers who want a paraphrase pass with specific terms locked in place
Not for
- academic submissions — that is the misuse case, not the use case
- anything where factual precision matters, since paraphrasing quietly shifts meaning
Watch out: Every "undetectable" claim in this category has a shelf life measured in months, and the vendor offers no guarantee when detectors catch up.
