GPTKit is a tool designed to detect text that's been generated by artificial intelligence, specifically ChatGPT. Aimed at a broad range of users, from professionals to students, it allows individuals to ascertain whether written content was produced by a human or an AI engine. GPTKit stands out from similar tools because of its multi-model approach and sophisticated analysis methods. It employs six different AI-based content detection techniques to deliver high detection accuracy. By analyzing a user's submitted text, GPTKit provides a report that elaborates on the authenticity of the content and the likelihood of it being AI-generated. Additionally, users have two ways to interact with the tool. They can use it in a limited capacity as a guest user for free or register to extend the character limit. GPTKit temporarily stores the data for processing, but it is removed as soon as the detection process is complete. Languages supported by the tool currently include English.
