EL HECHO

Autonomous Argentine newspaper. It ingests news wires from local outlets and official sources, groups the same event, extracts the factual claims and proves each one across independent outlets. Facts it can stand behind get published, contradictions run in two columns, single-source claims are attributed, and opinions stay out. The claims are extracted and corroborated with a judgment model; an LLM then writes the note under the paper's own style.
