GPTKit

What GPTKit is

GPTKit analyzes text and labels it as human-written or ChatGPT-generated. It is available on the web and through an API, and currently supports English. The maker says the detector combines six AI-based methods, was trained on 1 million datasets, and produces authenticity and reality reports. It reports approximately 93% accuracy, based on testing 100K+ human and ChatGPT responses. Each request includes up to 2048 characters free, including for guests; the Free Plan allows up to five requests per minute. Monthly plans add larger character and request limits, faster processing, and team capacity. Unlimited (Personal) costs $5 a month; Unlimited (Team) costs $10 a month and includes API access; Unlimited (Institution) costs $20 a month and includes API access. Team credits can be shared among members. GPTKit says submitted text is temporarily stored for processing and removed when detection is complete, while its privacy policy notes it cannot guarantee absolute security. The service is operated by Dreamsoft Innovations Private Limited, which describes itself as based in Mangaluru, India.
