What does GPTinf actually do?

GPTinf is a writing suite with six tools: an AI humanizer, an AI detector, a paraphraser, a plagiarism checker, a readability checker and a grammar checker. You typically humanize a draft, then check it for AI signals, plagiarism and readability before publishing or submitting.

Is there a free version?

Yes. The AI detector is advertised as free and unlimited, and there is a free tier so you can try the platform. Humanizer and paraphraser word allowances increase on the paid Lite, Pro and Unlimited plans.

How much do the paid plans cost?

The site lists Lite at $4.99 per month, Pro at $12.49 per month, and Unlimited at $29.99 per month, with the main difference being how many humanizer and paraphraser words you get each month.

Will humanized text pass AI detectors?

No tool can guarantee a specific result, and detector scoring changes over time. GPTinf's approach is to reduce the statistical patterns detectors often flag and let you review segment-level risk, so treat its output as one input rather than a promise.

Can I keep important words unchanged?

Yes. The Freeze option lets you lock terms, names or jargon so the humanizer and paraphraser leave them exactly as written.

Does GPTinf check plagiarism?

Yes. Its plagiarism checker scans your text against web sources, returns a plagiarism percentage, highlights flagged sentences and links each match to the source URL.
