GPTKit

GPTKit is a web-based tool designed to detect whether a piece of text was written by a human or generated by an AI model like ChatGPT. Users can paste text directly into the tool or upload files for analysis. The service is built to help individuals and professionals quickly verify the origin of written content. It works by analyzing submitted text using a multi-model approach. GPTKit employs six different AI-based detection techniques to assess the content. The system is trained on a dataset of over one million samples and claims an accuracy rate of approximately 93%. After processing, it provides a result classifying the text as human- or AI-generated, along with a report on its authenticity. The tool is particularly useful for educators reviewing student work, editors checking submissions from writers, and anyone who needs to ensure content originality. A free guest tier allows for the analysis of the first 2048 characters of text, with registration offering a higher character limit. For teams, GPTKit supports shared credit pools, making it suitable for classroom or departmental use.
