24 alternatives to Factifi – Real-Time Fact-Checking Content
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…

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…

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 --…
