ZeroGPTとは？

ZeroGPT is an AI content detection and writing toolkit centered on identifying likely AI-generated text. The home page positions it as a trusted detector for ChatGPT, GPT-5, Gemini, and other LLM outputs, with related tools for plagiarism checking, paraphrasing, summarizing, grammar correction, translation, and AI humanization.

The product is aimed at educators, businesses, creators, and other users who need to review authorship, refine drafts, or streamline writing workflows. The site also offers API access and business pricing for organizations that want to integrate ZeroGPT into their own systems or workflows.

よくある質問

How does ZeroGPT AI Detector work?

ZeroGPT analyzes text for linguistic and statistical signals associated with AI-generated writing, then returns an overall AI-likelihood score and highlights passages that appear AI-like.

What text length works best?

The FAQ says the detector performs best on about 150–200 words or more. Longer text, especially 500–1,000+ words, tends to produce more stable results.

Does ZeroGPT only detect ChatGPT outputs?

The site says ZeroGPT targets multiple LLM families, including GPT-series, Claude-style, Gemini-style, Grok, Perplexity AI, DeepSeek, and LLaMa models, rather than only ChatGPT outputs.

Will my text be stored or published when I check it?

No. The FAQ says user text is not saved, shared, published online, or used to train the AI detection model. The content is processed to generate the result and then discarded.

Does ZeroGPT support different languages?

Yes. The FAQ says ZeroGPT supports all available languages across its tools, and the home page says the detector is trained on all languages and multiple LLM models.
