Overview

What's happened in a given topic since a given date? Pass a free-text topic + ISO date; receive a deduplicated, ranked list of recent events drawn from US federal regulations, US House + Senate roll-call votes, academic papers (arXiv + PubMed + Semantic Scholar), and federal court opinions. Each event includes title, 1-2 sentence summary, date, source label, source URL, and a 1-5 significance score. Designed so an AI agent can spend one call to catch up on a domain since its LLM training cutoff. LLM-backed source routing and synthesis.
