Longitude

Longitude is an AI news reader that clusters the same story from 70+ international outlets across 20+ countries so you can see how the world reports one event from every angle. Built for readers who want more than a single national perspective, it groups coverage of a story and applies transparent corroboration scoring to show what is corroborated, what is disputed, and what your local media is not covering. A dedicated "Not in US Media" filter surfaces stories underreported in American outlets, alongside category feeds for World, Politics, Conflict, Economy, Science & Tech, Health, and Environment. The platform pairs AI-powered clustering with a raw article feed, a Lookup tool to find coverage of a specific topic, and a Topic Explorer, and it lists its full source set openly. Longitude is web-based, installable to a phone home screen as a PWA, and currently in beta. If you are looking for the best AI for comparing global news coverage or a news aggregator that scores cross-source corroboration, Longitude fills that gap with a stated no-ads, no-paywalls, open-sources policy. It is supported by donations rather than advertising, and its AI summaries prompt readers to verify against original sources.
