    I built this tool because I wanted a way to just take a bunch of URLs or domains, and query their content in RAG applications. It takes away the pain of crawling, extracting content, chunking, vectorizing, and updating periodically. I'm curious to see if it can be useful to others. I meant to launch this six months ago but life got in the way...

    This is a quick prototype I built for semantic search and factual question answering using embeddings and GPT-3. It tries to solve the LLM hallucination issue by guiding it only to answer questions from the given context instead of making things up. If you ask something not covered in an episode, it should say that it doesn't know rather than providing a plausible, but potentially incorrect response. It uses Whisper to transcribe, text-embedding-ada-002 to embed, Pinecone.io to search, and text-davinci-003 to generate the answer. More examples and explanations here:…

    Hey HN! I got the idea for this during the Lovable AI competition and decided to turn it into a Chrome extension. TrueSift helps verify the accuracy of online content in real time. What it does: - Uses AI to analyze text on any page and highlight questionable claims. - Provides quick fact-check summaries and trusted sources without leaving the page. - Lightweight and privacy-conscious (no unnecessary data collection). Why I built it: Misinformation spreads fast, and I wanted a tool that makes truth-checking effortless for readers, journalists, and researchers. Try it out: truesift.dev I’d…

    I'm Arthur, and I wanted to share an MVP for Marqt.org, which lets you crowd-source the truth. John Stuart Mill said that "Truth emerges from the clash of ideas." In that spirit, Marqt brings two adversarial sides together to quantify truth and showcase the best arguments for each side. It is inspired by markets, where buyers and sellers discover a product's true price and update it dynamically. The ultimate aim is to build an open-source semantic knowledge base that represents the collective wisdom of humanity in real-time. If we can do this, I believe it can solve the problem of…
