Multi-stage research engine.

Semantic Filtering

Cerna reads each source for meaning, not just keywords. Articles that sound relevant but aren't get dropped before they ever reach you.

Entity Resolution

Five outlets, one event. Cerna recognizes when articles cover the same company, person, or filing — so you see one finding, not a dozen variations of it.

Predictive Synthesis

A hire here. A filing there. A price move on the third. Cerna spots when small, scattered signals add up to something bigger — and tells you before any single article would.
