    Hi, co-founder of markets.sh here. We are doing a lot of news processing and analysis around stocks and companies. One feature people like to use is “alerts” at certain price points. We have now extended this with LLM filters on the whole news feed so that you can create (near) real-time webhooks on arbitrary events like: - Notify me when Nvidia is worth 10 trillion - Notify me about AI breakthroughs - Notify me when Intel is the market leader again - Notify me about successful Starship launches - Notify me when a war breaks out - Notify me about bankrupt unicorn startups - Notify me about…

    Hey HN, I’m Dan. I’ve been working on forecasting for the last six years at Google, then Metaculus, and now at FutureSearch.

    PredictionHunt – Compare probabilities across prediction marketsOct 2025 · predictionhunt.com · ▲12

    Hey HN - my friend and I built Prediction Hunt, a site that aggregates data from prediction markets like Kalshi, Polymarket, and PredictIt into one simple dashboard. It updates every few minutes, shows probabilities for each event, and even highlights arbitrage opportunities when markets disagree. I made it after getting tired of flipping between tabs just to see how each market was pricing the same question. Would love feedback on the product, data accuracy, and any ideas for what you'd want to see next.

    Hi HN, Today we’re launching GPT-4 answers on Phind.com, a developer-focused search engine that uses generative AI to browse the web and answer technical questions, complete with code examples and detailed explanations. Unlike vanilla GPT-4, Phind feeds in relevant websites and technical documentation, reducing the model’s hallucination and keeping it up-to-date.
