Description
ZeroGPT.cc is a free AI text detector that determines whether content was written by a human or generated by AI. It uses machine learning algorithms and natural language processing trained on large amounts of human- and AI-written data to predict the origin of a text and display the percentage of AI-generated content for in-depth analysis. It works across all versions of GPT models and detects output from GPT-5, GPT-4, GPT-3, LLaMA, Claude, Google Gemini, Grok, Jasper and other AI services.
The tool provides sentence-by-sentence analysis that highlights flagged content in yellow, orange or red so you can see which areas to improve, along with revision suggestions to make the text sound more human. It also includes a readability score that reflects how simple or complex your sentence formation is, and an API integration for embedding text detection into existing workflows, applications and systems. A split tool helps separate long text into manageable chunks.
ZeroGPT.cc emphasizes accurate, fast and easy detection, states it developed its algorithm after analyzing more than 20 million AI- and human-generated articles, and offers unlimited free AI checks with no login. It does not store submitted data after results are returned, supports multiple languages, and is used for SEO content, academic work and marketing content by publishers, educators, students and content professionals.
