AI Content Detector

AI Content Detector is a free web-based tool designed to identify whether a piece of text was written by a human or generated by AI models such as ChatGPT, Gemini, GPT-4, GPT-5, OpenAI, and Bard. It provides real-time analysis, letting users paste text directly or upload multiple text files at once. The tool is aimed at writers, educators, and professionals who need to verify originality before publishing or submitting content. The platform highlights AI-written sentences and displays a gauge showing the proportion of AI contribution within the text. It automatically generates downloadable PDF reports, which can serve as evidence that content is free of AI-generated text. A high-precision model trained on multiple languages supports all world languages, making it useful for global teams and multilingual content. The user experience centers on a straightforward dashboard where uploaded files are checked automatically. There is no mention of an account or payment requirement, positioning it as an accessible starting point for quick content verification. However, users looking for advanced collaboration, API access, or desktop applications may need to combine it with additional tools.

MyDetector AI

MyDetector AI is a free online AI content detector that identifies text generated by ChatGPT, Gemini, Claude, and other popular AI writing and paraphrasing tools. It analyzes writing style and structure to spot patterns typical of machine-generated content, such as repetition, unnatural transitions, and a lack of human inconsistency. Users can paste text directly into the browser-based checker or upload PDF, Word, PPT, and TXT files for large-document analysis. Beyond simple detection, MyDetector provides real-time results with sentence-level highlighting and a 0-100% AI probability score. It also offers a dual-model choice for either a fast high-speed overview or a deeper, granular analysis. After detection, users can switch to the built-in AI humanizer to rewrite AI-generated passages into a more natural, human-like style, and can compare AI and human text in real time to guide revisions. The tool is designed for anyone who needs content authenticity: educators reviewing student assignments, editors checking press releases, content creators and bloggers polishing articles, marketers refining copy, and corporate or research teams validating reports. It is completely free, requires no account, supports multiple mainstream languages, and emphasizes privacy by not storing detected content. With its combination of advanced detection, file handling, and humanization features, MyDetector AI serves as an all-in-one authenticity assistant for modern writing workflows.
