FactFrame

What it does

Perfect for: • Documentary skeptics 🎬 • News junkies 📰 • Students researching 📚 • Anyone tired of misinformation 🚫 How it works: - Install the Chrome extension - Add your API key (OpenAI, Anthropic, or OpenRouter — free tiers work!) - Pick your search source (Tavily, Exa, Perplexity, Brave) Open any YouTube video — fact checks appear automatically Why it's different: ✅ Works on livestreams and normal videos ✅ Bring your own API keys = full control, lower cost ✅ Use free tiers = $0 to run

  Time-Saving Chrome Extension for Journalists Doing Research on YouTube2023 · chrome.google.com · ▲14

  Hello Hacker News community, I've been developing a simple Chrome extension designed to assist journalists and researchers or learners in their YouTube investigations. You can swiftly identify specific segments within a video using semantic searches, powered by the OpenAI API. This transforms hours of potential scrubbing into moments of precision seeking.

  Open source alternative to Perplexity Comet2025 · browseros.com · ▲291

  Hey HN, we're a YC startup building an open-source, privacy-first alternative to Perplexity Comet. No invite system unlike bunch of others – you can download it today from our website or GitHub: https://github.com/browseros-ai/BrowserOS --- Why bother building an alternative? We believe browsers will become the new operating systems, where we offload much bunch of our work to AI agents. But these agents will have access to all your sensitive data – emails, docs, on top of your browser history. Open-source, privacy-first alternatives need to exist. We're not a search or ad…

  TL;DR2025 · tl-dr.tv · ▲199

  I love Hacker News but I rarely have time to read full articles / comments, so I built a simple site to summarize the top posts & comments to make it easier to get a big picture. A few implementation details: - It pulls the top stories from the HN Firebase API (`/v0/topstories`) - Filters stories with >200 points - Uses Claude Sonnet for post + comment summaries - Tries to capture the sentiment of the comments (still working on improving this) - Refreshes both posts + summaries hourly It has already helped me I hope it helps you! Please let me know if you have any feedback --…

  Factifi – Real-Time Fact-Checking Content2025 · chromewebstore.google.com · ▲8

  Hi HN — we built Factifi, a Chrome extension that does instant fact-checking on anything you’re reading or watching. Please keep in mind, this is just an MVP and will be buggy and fail. We were constantly pausing podcasts and Substack posts to ask, “Wait, is that actually true?”. After too many 30-minute Google rabbit holes, we decided to automate the work. What it does • Extracts claims from articles, blogs, YouTube videos (and even images) • Assigns a verdict + confidence score using live web search, a 200 M-paper research index, and a few proprietary datasets • Flags likely deepfakes and…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
