GPTinf
Detect, humanize, and clean AI-written text before submission
GPTinf rewrites AI-generated text so it reads like a person wrote it, then shows the score across eight AI detectors below the output. The rewriting engine isn’t an LLM; it restructures sentences at the grammatical level to preserve meaning and register. The platform also includes a plagiarism checker, grammar checker, paraphraser, and readability checker. It works without an account.
