AI Detect

AI Detect is a specialized online tool designed to identify text generated by artificial intelligence models, including ChatGPT, Claude, Gemini, and other large language models. Its primary function is to analyze any piece of written content and return a detection score ranging from 0% to 100%, indicating the likelihood that the text was produced by an AI rather than a human. The tool operates on a simple interface where users can paste text directly into a text box or upload files (such as .txt, .docx, or .pdf) up to 4 MB in size. A character or word limit is enforced for free users, typically around 750 words per check, with a set number of daily uses (e.g., five remaining checks shown in the interface). Paid subscriptions unlock higher word limits, file uploads, and unlimited scans. Beyond basic detection, AI Detect provides two additional metrics to help users understand the nature of the text. The first is a readability score, measured on a scale from 0 to 100, where higher scores indicate text that is easier to read and understand. The second is a grade level assessment, which estimates the U.S. school grade required to comprehend the content—ranging from elementary to college levels. These metrics allow educators, publishers, and content reviewers to evaluate not only the origin of the text but also its complexity and suitability for a target audience. A key feature of AI Detect is its built-in AI humanizer. When a user identifies a piece of text as AI-generated, they can run it through the humanizer to rewrite the content in a way that makes it undetectable by other AI detection systems. This function is particularly useful for students, marketers, and writers who want to refine machine-generated drafts into more natural, human-sounding prose while preserving th
