Doublecheck

What it does

Real-time AI fact-checking for live podcasts and video streams. Doublecheck detects factual claims as they're made and verifies them against authoritative sources in seconds, not hours.

Doublecheck listens to podcasts and video streams, detects factual claims, and verifies them with sources — in seconds, not hours. Paste any YouTube video or podcast link. Doublecheck handles the rest — no plug-ins, no uploads. Streaming audio is transcribed and parsed. A claim model flags statements that are checkable: numbers, attributions, comparisons. Each claim is researched against authoritative sources and returned with linked evidence and a confidence score. Each fact-check is structured: original claim, verdict, evidence, sources, confidence. We populate cards from real research — nothing on this page is synthesized. Multimodal video understanding catches on-screen charts, data,…from doublecheck.metisos.co

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
