GPTinf
AI writing toolkit for humanizing, detecting, and refining AI-generated text
GPTinf is a free AI writing toolkit that helps users humanize AI-generated text, detect AI content, check plagiarism, and improve readability and grammar in one
About this launch
GPTinf is a comprehensive writing platform offering six integrated tools: an AI Humanizer that rewrites robotic text to sound natural while preserving meaning, an AI Detector that cross-checks text against eight detection systems, a Plagiarism Checker that scans against web sources, a Paraphraser that allows selective rewrites with word-locking, a Readability Checker that scores clarity using Flesch-Kincaid levels, and a Grammar Checker that catches contextual errors.
The platform was created by a student to help people make AI writing feel natural while keeping content authentic and original. It serves students, writers, content creators, marketers, and professionals across academic essays, assignments, blog posts, marketing copy, and business reports.
GPTinf uses custom non-AI algorithms for its humanizer rather than AI refining AI. All tools include free tiers accessible without registration. Premium paid plans offer higher word limits and additional features like multiple writing modes and priority support.
