GPTKit is an AI text detection tool distinguishing human-written from AI-generated content, specifically tuned to identify ChatGPT output. It combines six different AI-based detection techniques rather than relying on a single method.
The model is trained on 1 million datasets and benchmarked against over 100,000 real human and ChatGPT responses, reporting roughly 93% accuracy. It supports file upload for bulk checking, generates authenticity and reality reports, and offers team accounts with shared credits.
GPTKit targets teachers, professionals, students, content writers, employees, and freelancers checking content for AI generation. Free tier: 2,048 characters per request for guests, no account required. Paid plans increase character limits after registration; team plans are available. English only.
