About GPTKit
GPTKit is a web tool that analyzes submitted text to estimate whether it was written by a person or generated by ChatGPT. It applies six different detection methods and returns a result along with a report on the authenticity of the content. The first 2048 characters of each request are free for guest users, and registering raises the character limit. English is the only supported language, and the site recommends entering more than 50 words for better results. GPTKit says its detector is trained on a dataset of one million items and reports accuracy of approximately 93%, based on testing with over 100,000 responses from humans and ChatGPT, with further improvement ongoing. Submitted text is stored temporarily for processing and removed from the servers once detection is complete.
