Advacheck

Advacheck is a web-based tool designed to detect whether a piece of text was written by a human or generated by an artificial intelligence. It analyzes writing patterns to identify content created by models like ChatGPT, Gemini, Llama, and others. Users can paste their text into the tool to receive an analysis of its likely origin.

The tool uses its own AI, built on Large Language Models (LLMs), to perform the detection. The company states its system is continuously improved and aims for a very low false positive rate of under 0.5%. This means it is tuned to minimize incorrectly flagging human-written text as AI-generated. A key differentiator mentioned is the team's experience in language model development dating back to 1997.

Advacheck is particularly useful for students who need to verify their work before submission, publishers and researchers who must protect intellectual property, and marketers who want to ensure their content is valued by search engines. It helps these groups maintain credibility and avoid the negative consequences associated with undisclosed AI-generated content.
