Key Features
Multi-Signal Quality Ranking Results aren't just sorted by date — they're ranked by a multi-signal relevance score that weighs upvotes, engagement, source authority, and cross-source convergence. When multiple platforms discuss the same topic, convergence detection highlights consensus views.
Cross-Source Convergence Detection When Reddit, X, and Hacker News all discuss the same topic, Last30Days detects the overlap and highlights where communities agree or disagree.
Comparative Mode Compare two topics side-by-side:
