ZeroGPT
What ZeroGPT is
ZeroGPT is a web and API service for checking text for AI-generated content. Its detector returns percentage scores and sentence-level breakdowns, and the site says it recognizes text from ChatGPT, Claude, Gemini, DeepSeek, Llama, Mistral, and other models. A free plan provides detection for up to 5,000 characters per check; free accounts can analyze uploaded .txt, .docx, .pdf, and .odt files up to that length. The service also includes a humanizer, which rewrites AI-generated text in seven writing tones, and a plagiarism checker that compares submissions with web pages, academic papers, and other published content. Each offers free use up to 5,000 characters. Developers can use the API for detection and humanization, with webhooks that support signature verification and automatic retries. The privacy policy says submitted text and files are not stored on its servers, while third-party advertising cookies and trackers are used. Its FAQ cautions that detection is not fully accurate and recommends human judgment alongside automated results.
