AI Text Detector is an online content-verification service that helps users assess whether writing may have been generated by artificial intelligence. Its free detector accepts text for analysis without requiring an account, with a submission limit of 50,000 characters and results typically delivered within seconds. The service says its machine-learning models examine writing patterns, structure, and linguistic markers across major tools, including GPT, Claude, Gemini, and LLaMA.

Users can review an overall confidence score, sentence-level analysis, and a breakdown of detected patterns. The site also offers API access, including batch processing and webhook support, and describes enterprise options such as custom models, volume pricing, single sign-on, and dedicated support. Its stated audiences include educators, students, SEO teams, recruiters, writers, and publishers.

AI Text Detector emphasizes privacy, stating that submitted text is analyzed in real time and immediately discarded rather than stored or used for training. The site reports support for more than 150 languages and approximately 98% detection accuracy, while noting that results can vary with text length, language, and editing. Its resources include a blog, research, benchmarks, and comparisons of detection tools.
