Vercel Labs Releases ai-facts: Real-Time Spoken Statement Fact Checking With AI SDK, Perplexity, and Deepgram

GitHub·low signal

Vercel Labs published ai-facts, a Next.js demo that transcribes spoken audio in real-time via Deepgram, then cross-references claims against live web data using both OpenAI and Perplexity for fact verification. Results stream back with explanations for why statements are true or false. One-click Vercel deployment. Small at 147 stars but demonstrates a practical AI SDK pattern — combining speech transcription, dual-LLM verification, and web-grounded search in a single pipeline.
