PolyBrief is an AI-powered news intelligence platform built to help you understand what is actually happening in the world — not just surface-level headlines.
We track hundreds of global topics — from geopolitical conflicts and elections to sports, entertainment, and technology. For each topic, our system continuously ingests news from thousands of sources, groups events by significance, and surfaces the most important developments in a structured, readable format.
Every topic page includes an AI-generated briefing that synthesizes recent developments, a chronological timeline of key events, and traceable source chains so you can always verify what you read.
News ingestion. We pull news events daily from NewsAPI.ai's Event Registry — a service that aggregates coverage from thousands of publishers worldwide.
Grouping and filtering. Events are matched to topics using semantic concept matching. Low-quality or irrelevant events are filtered out — only events with meaningful coverage volume proceed.
AI synthesis. Claude (Anthropic) processes the grouped news events and generates structured timeline entries and narrative briefings. Each briefing is anchored to a specific time period so the analysis stays accurate and dateable.
Transparency. Every claim in a briefing links back to the source stories and articles. You can always trace what the AI read to reach its conclusions.
Most news aggregators show you a list of headlines. PolyBrief shows you the story — the arc of events over time, what changed and when, and how different developments connect. The timeline format makes it easy to catch up on a topic you haven't followed in weeks, or to understand a breaking story in context.
We don't have a political angle or editorial agenda. Our briefings are generated from the news record as it exists, with sources you can verify.
