ZeroGPT delivers industry-leading accuracy and is continuously improved to maintain best-in-class performance—pushing toward >98% on internal evaluations.
We retrain regularly, calibrate thresholds, and run diverse test suites. For optimal results, analyze 150–200+ words and review the highlighted passages alongside the overall score.

It analyzes linguistic and statistical signals learned from human and AI text to estimate the likelihood that text was generated by an LLM.
Signals include token patterns, burstiness, entropy, and ensemble classifier features trained on mixed datasets. Output = an overall score plus highlighted passages that appear AI-like.

At least 150–200 words; longer text (500–1,000+) improves stability.
Very short or heavily edited snippets carry fewer signals; consider merging sections before checking.

No—ZeroGPT targets multiple LLM families (e.g., GPT-series, Claude-style, Gemini-style, and others).
Coverage is broadened through ongoing training across prompts, domains, and model updates.

Paraphrasing can reduce some signals, but robust detectors and cross-checks help maintain reliability.
Combine the AI Detector with the Plagiarism Checker and proper citations when refining drafts.

Highly polished, formulaic, or low-entropy writing can resemble AI.
Strengthen authentic voice with specific facts, citations, examples, and varied sentence rhythms; review the highlighted segments.

Add concrete details, sources, and varied sentence structures.
Avoid generic boilerplate and repetitive phrasing; keep consistent author voice and topical specificity.

Plagiarism finds matches to existing sources; the AI Detector estimates AI-generation likelihood.
Use both: plagiarism answers “copied from where-”, the detector answers “likely written by an LLM-”.

Yes—transport encryption, access controls, and isolated processing.

By default, we do not publish, save or sell user text.

No. The privacy of our users is our top concern. When you check your text on ZeroGPT, it is not saved, shared, published online, or used to train our AI detection model.
Your input is processed only to generate your result and then discarded. We do not publish or sell user text.

No-retention modes are available for API/enterprise.

We only store your email address, name, and a hashed password. Your data is encrypted at rest and our infrastructure is hosted in Germany and operated in accordance with the GDPR, ensuring strong data protection and confidentiality.

Paste text or upload common formats (e.g., .txt, .docx, text-based .pdf).
For image-based PDFs, run OCR first; clean plaintext inputs provide the most reliable highlights.
