AI Scanner is an online detection platform focused on identifying AI-generated texts. It not only captures native outputs from mainstream models such as ChatGPT, Claude, Gemini, and Perplexity, but also identifies content that has been manually modified or rewritten with tools. Its core advantage lies in its high detection accuracy of up to 99%, continuously fine-tuning the model to address evolving LLMs. For students, teachers, and content researchers, it provides a safe and privacy-protected environment, ensuring text originality and academic integrity without storing user data. Its positioning is to provide transparent and reliable authenticity assessment services for the education and content creation fields.
