GPTKit

GPTKit is an online tool for detecting text generated by ChatGPT and other language models. It helps distinguish human writing from AI content, which can be useful for educators, editors, businesses, and website owners.

How GPTKit works

GPTKit uses a multi-model approach: several algorithms analyze writing style, structure, and statistical patterns in the text. In total, it applies 6 different detection methods and reports accuracy of up to 93% when the text is long enough.
