ZeroGPT is a browser-based AI content detector built to flag text that was likely written by ChatGPT, Gemini, Grok, DeepSeek, or other large language models. It's aimed at teachers, editors, and content managers who need a quick second opinion on whether a piece of writing was AI-generated, plus a set of writing tools bundled around the same account.
What does ZeroGPT do?
The core tool scans pasted or uploaded text, up to 15,000 characters at a time, and returns a percentage estimate of how much of it appears AI-generated, with individual sentences highlighted so you can see exactly which passages triggered the flag. The company calls its detection process DeepAnalyse, a multi-stage model trained on text scraped from the web, academic datasets, and synthetic text produced by multiple language models.
Beyond detection, ZeroGPT bundles a full writing toolkit under one account: an AI humanizer that rewrites AI-flagged text to sound more natural, a plagiarism checker, a paraphraser, a grammar checker, a summarizer, a translator, and an AI image detector for spotting deepfakes and AI-generated photos.
Core features
- AI/GPT text detector that highlights AI-suspected sentences and produces a downloadable PDF report as documentation.
- AI Humanizer tool that rewrites flagged text while trying to preserve the original meaning.
- AI Image Detector for identifying AI-generated or manipulated images.
- Plagiarism checker that compares submitted text against a large index of existing web content.
- Batch file upload so educators or editors can check multiple documents in one pass.
- Detection and writing tools that work across multiple languages, not just English.
- A background remover tool and a general-purpose AI chatbot called ZeroCHAT included in the same product suite.
- WhatsApp and Telegram bots that let you run detection, summarizing, or translation from a messaging app instead of the website.
Use cases
Teachers and academic staff use ZeroGPT as an AI content detector to screen student submissions for AI-written work before grading. Content teams and editors use it as a pre-publish check on freelance or AI-assisted copy, especially when a client or platform requires original, human-edited writing.
The humanizer and paraphraser tools get used the opposite way too, by writers who draft with an AI assistant and want a pass that lowers the detectable AI signal before submitting the piece elsewhere.
Pricing
ZeroGPT offers a free forever plan with no credit card required for the core detector and basic tools. Paid Personal and Business/EDU plans are billed monthly or annually, with a discount for annual billing, and exact tier pricing is set at signup and varies by plan level. Business and Enterprise customers can request a custom quote, and a separate pay-as-you-go API is available for developers who want to integrate detection into their own software.
