ClaimCheck is a real-time voice-first fact-checking assistant that lets users speak a claim and receive an instant spoken verdict with a confidence score. Built on Cloudflare for hosting and agent orchestration, the platform runs a transparent pipeline from Audio In → STT → intent detection → verification agent → TTS → Audio Out, with each step visible live in the interface. To verify claims, ClaimCheck combines Brave Search for live web evidence with OpenAI, Anthropic, and Gemini for multi-LLM consensus reasoning. It then calculates a weighted confidence score to classify statements as False, Uncertain, or Verified, while highlighting the most suspicious parts of the claim. For the voice layer, ElevenLabs powers the speech output, making the experience fast, natural, and conversational. By combining Cloudflare edge infrastructure, real-time retrieval, multi-model verification, and high-quality voice interaction, ClaimCheck turns fact-checking into a seamless spoken experience.
