Weekend project, real-time conversation fact-checking using Perplexity

Hi HN! I recently discovered Perplexity.ai and I was amazed! I built a product this past weekend that I felt should just exist in the world. With a knowledge engine such as Perplexity, a realtime fact checking platform is now finally possible. DeepFact runs in the background as you speak and actively extracts claims and fact checks them. The app is built using NextJS, Deepgram API(nova-2 model) for speech to text, and Perplexity API(llama-3.1-sonar-small-128k-chat) for real-time fact checking. It is completely free, just add your own API keys to give it a try. There's also a simulated demo using Elon-Trump's interview on X if you just want to see how it works. Ideally this product would be used to fact check any conversation in realtime: public speeches/presentations, lectures, meetings, debates, podcasts. The use cases seem endless. There are times where it fails and hallucinates source URLs or it cites itself. There is plenty of room to improve the fact-checking algs. Please try it out and I would love to hear any feedback or comments on how this could be used and ways to improve it. Thanks!
