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. Whether you're sifting through extensive interviews, press conferences, and event footage on YouTube, or you require a quote from a video source, This extension is a handy tool. It also aids in quickly fact-checking statements made in…

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;DR▲199I 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 --…

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…

Hey HN! My name is Andrew, and I'm thrilled to share with you a project I've been working on called Factful. I'm a high school student with a passion for tackling misinformation online. Inspired by the need for more reliable content verification tools, I decided to create Factful. It's an AI-powered web app designed to revolutionize how individuals and organizations verify content. Unlike traditional grammar checkers, Factful provides a comprehensive analysis that goes beyond just grammar. It evaluates context, factuality, coherence, and more to ensure the accuracy and credibility of…

TrueSift▲7Hey 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…

Hey HN! We’re a group of high school students who built Factful, a Chrome extension that helps with research, fact-checking, and writing—all inline. When we first launched Factful as a web app, we got a lot of feedback asking for a more integrated experience, so we built a Chrome extension to let you fact-check and look up information without switching tabs. Making this work inside Google Docs was way harder than expected. Since Docs renders text using a canvas instead of regular HTML, we had to come up with creative workarounds to analyze and interact with what’s being written. It took a…

Hi Hacker News, I developed an open source browser extension for summarizing Hacker News articles with OpenAI and Anthropic LLMs. It currently supports Chrome [1] and Firefox [2] (desktop). The extension adds the summarize buttons to the HN front page and article pages. It is bring-your-own-key, i.e. there's no back end behind it and the usage is free, you insert your API key and pay only for tokens to your LLM provider.

AI is advancing fast, but the hallucination problem persists. Most products have no verification layer. They just hope the model gets it right. Factagora API gives you programmatic access to a knowledge graph of fact-checked claims, evidence, and causal relationships extracted from global news and research sources. 6 endpoints: News Search, Fact Checker, Evidence Finder, Deep Research, Timeseries, Causality Graph. Start with 100 free credits, no credit card required. Happy to answer questions about how we built it.

Hi! As a side-project this summer (partly to have an excuse to try out Claude Code ;D), I built a Chrome extension that hides content that doesn't match user preferences. Example usage: https://youtu.be/japjNSU3O7A The content + preferences are sent to an LLM, which decides if the content is relevant. You can use your own OpenRouter API key, but there's also a 'free tier' which uses my key (there's a daily quota with this option, though). The extension now also supports including images and video thumbnails in the filtering, although this is only available when using your own…

I'm sure you all saw the debate a few days ago, alongside all the tech influencoors giving their mid-takes about politics. Doesn't it get tiring? That's why I built mindfirewall a chrome extension that uses AI to filter out tweets. You'll never have to see politics, war, or negativity on your timeline again. In the future you'll be shocked you even allowed this stuff into your brain in the first place. Let me know what you think below, does it feel too much like censorship? would you use this?

Last week I benchmarked my open-source Deep Research tool against ChatGPT, Perplexity, and Gemini. I caught OpenAI fabricating 4-5 citations that don't exist. Gemini reduced real hazard ratios by 30-40%. So I built ASK Mode: every answer gets automatically verified against a second round of sources. Each claim marked [OK], [??], or [NO]. - ~400 verified answers for $1 - 2-3 minutes per query - No RLHF nannying - it answers what you ask - Full verification report with every response The gap between chat (unverified, stale training data) and deep research (20+ minutes) needed filling.…
