Theiaとは
Hold your LLM accountable Tired of second-guessing what you read online? Or wondering whether your AI chatbot is confidently making things up?

🔍 What Theia Does
Fact-Check Any Claim: Highlight any statement on a webpage and get an instant verdict with explanations and cited sources.
Audit AI Responses: Using ChatGPT, Claude, or Gemini? Theia analyzes AI outputs for hallucinations, factual errors, and sycophancy (agreeing just to sound helpful)!
