What is ZeroGPT?
ZeroGPT is a web platform whose core product is an AI content detector. You paste text or upload files, and its DeepAnalyse model estimates how much of the text was written by AI models such as ChatGPT, Gemini, Claude or DeepSeek. Every AI-generated sentence is highlighted and a gauge shows the AI percentage, and a PDF report can be generated for each check.
Beyond detection, the site bundles a set of text and media tools: an AI Humanizer that rewrites AI text in a more natural style, a Plagiarism Checker that searches billions of sources, a Paraphraser, Summarizer, Grammar Check, Translator, Word Counter and Dictionary. It also has separate AI Image and AI Video detectors, and an API for organizations. The service is also reachable through WhatsApp and Telegram.
