A hallucination detector for LLM output, from Komplex AI. Paste any AI response and get a calibrated probability that it's hallucinated, plus the type of error — fabricated facts, fake citations, misleading claims. Use it from a web app, a REST API, Python/JS SDKs, a LangChain integration, an n8n node, or an MCP server. Free tier, zero data retention. Probabilistic, and honest about its limits.
