Hallucination check
Hallucination check: a live fact-check of one claim by four independent AI models (GPT, Gemini, Grok, Claude), each searching the web separately. Returns a summary first: verdict (confirmed, disputed, unverifiable, or contested when the models split), agreement such as 4/4, mean confidence and a one-line headline. Then each model's verdict, reasoning and cited sources. Disagreement is shown, not hidden. 10-45 s.
