What does AI Detect do?
AI Detect is a web-based tool that analyzes text to determine if it was written by a human or generated by an artificial intelligence. You paste text directly into its interface or upload a file, and it provides a detection score. The tool checks content against several popular AI models, including ChatGPT, Google Gemini, and Meta's LLaMa. Its main job is to give users a clear answer about the origin of a piece of writing.
The tool works by processing the text you provide and running it through its detection algorithms. It claims 99% accuracy for identifying text from ChatGPT specifically. Beyond a simple AI/human percentage, AI Detect also gives you two extra metrics: a readability score and a U.S. grade level estimate. These help you understand how complex the writing is. A notable feature is its 'Undetectable AI' function, which is designed to rewrite AI-generated text to make it sound more human.
This tool is most useful for educators who need to ensure student submissions are original, and for content managers or marketers who want to verify the authenticity of articles or social media posts. It addresses a growing need in academic and professional settings where the use of AI writers must be identified and managed. The free tier offers a limited number of checks, making it easy to try before committing to a subscription for higher-volume use.
