Unfox AI

Unfox AI is a web-based tool that analyzes text to determine whether it was written by a human or generated by artificial intelligence. It examines writing patterns, including perplexity and burstiness, to identify the subtle traces that AI models leave behind. The tool works with content from various sources, including ChatGPT, Claude, and Gemini, and supports multiple languages. What makes Unfox AI stand out is its detailed reporting. Instead of just giving a percentage score, it highlights specific sentences that appear AI-generated, making it easier to understand the results. It also offers bulk processing capabilities and an API for integration into larger content management systems. The service is designed with privacy in mind, as it does not store the text you submit for analysis. Unfox AI is particularly useful for educators who need to verify the authenticity of student work, content editors who want to ensure articles meet originality standards, and hiring managers screening application materials. It helps maintain trust and integrity in environments where distinguishing human creativity from AI output matters.
