How AI is used
ContentDetector.AI is a browser-based tool designed to identify text generated by AI chatbots. It uses a model that combines OpenAI's GPT-2 with a Roberta model to provide a probability score on whether a piece of content is human-written or AI-generated.
The tool is designed for academics, digital marketers, and content creators who need to verify the originality of their materials. It supports the detection of content from models including ChatGPT (GPT-3.5, GPT-4, gpt-4o, gpt-o1), Gemini, and Claude.
Beyond AI detection, the platform includes utility tools such as word and character counters, a language detector for over 50 languages, and a plagiarism checker for chatbot responses.
Buyers should note that the tool works on probability and is not 100% accurate; it is intended to be used alongside human judgment to determine authorship.
