Title: LetMeCheckIt: Real-Time Fact Checker Tagline: Don't trust everything you hear. Verify live audio streams and podcasts against the truth in milliseconds. What we built: LetMeCheckIt is a live, real-time fact-checking application that listens to any audio (like a podcast playing in the background), transcribes it instantly, and uses AI agents to cross-reference claims against external and internal knowledge bases. How we used the tech (ElevenLabs & Gemini): We leveraged the ElevenLabs Scribe Live API (WebSockets) to establish an ultra-low latency, real-time transcription layer. As sentences stream in, we orchestrate them into logical chunks and feed them into Google Gemini using a specialized Cloudflare Agent (@cloudflare/agents). Added Google Drive integration to cover folders, and source files to cloudfare fast RAG (Retrieval-Augmented Generation). All to verify the claims. What makes it special: Most transcription apps transcribe after the fact. LetMeCheckIt sits in the background of your life—whether you're listening to a space podcast or sitting in a meeting—and dynamically pops up glassmorphic cards indicating TRUE, FALSE, or UNSURE (or LAPSUS), providing short explanations and direct source links before the speaker even finishes their next sentence. Access to public facts live on the start screen for free 120s transcription or pay (now it's dummy) to have your verification rolling privately and infinitely.
