ZeroGPT Plus

ZeroGPT Plus is a web-based tool that checks any block of text you paste or upload to determine the likelihood it was written by an AI. It provides a percentage score showing how much of the content appears to be AI-generated versus human-written. The tool supports analysis for a wide range of popular AI models and offers different modes for checking general articles, academic papers, or student assignments. It’s a straightforward utility designed to give you a quick, data-driven opinion on the origin of a piece of writing.

The tool works by analyzing the text's sentence structure and comparing it against known patterns from various AI models. It then generates a detailed report with its findings. What makes it stand out is its broad model coverage, supporting detection for ChatGPT, Claude, Gemini, Grok, DeepSeek, and Copilot. It also provides a visual, step-by-step breakdown of its analysis process, showing it checking structure, comparing models, and calculating probabilities.

This tool is most useful for educators verifying student work, editors and content managers ensuring originality, and anyone who needs to validate the authenticity of written content. Real-world use cases include a professor checking an essay for AI assistance, a blog editor vetting freelance submissions, or a team lead ensuring company communications maintain a human touch.
