FAQ
What is AI Hallucination Detector?
An online AI hallucination detection tool. It detects hallucinations and factual errors in AI-generated content with cross-validated accuracy checks. Input: the AI-generated text you need to verify. Output: hallucination score, risk flags and verification sources with one-click copy and download. Everything runs in your browser — no uploads.
What is an AI hallucination?
AI hallucination is when a large language model generates content that looks plausible but is actually wrong or fabricated — including invented facts, incorrect figures, fake citations and non-existent links. It is a well-known limitation of LLMs.
What does the detection rely on?
The detector cross-references the answer against authoritative knowledge bases (Wikipedia, official documentation, academic databases) and live search results, combining semantic similarity and factual consistency to compute a hallucination score.
Can it identify fabricated citations?
Yes. Citation verification mode checks each paper title, author, journal and link for authenticity, flagging publications that don't exist and sources that can't be reached.
How accurate is the detection?
Accuracy exceeds 90% on public fact-checking benchmarks. That said, hallucination detection is inherently probabilistic, so we recommend human review of high-risk passages.
Which languages are supported?
Supports 20+ languages including Chinese, English, Japanese, Korean, French and German. Mixed-language texts are handled correctly too.
