Meridian, the grain-first AI data analyst

Field notes

Meridian’s workflow begins by asking what each row represents rather than immediately generating charts. Its sample distinguishes invoice grain from line-item grain, notes that “Acme Supplies” maps to three customer IDs, and recommends using customer_id for concentration analysis. The site says profiling runs in the browser and that raw records are not kept, while the resulting briefing includes charts, risks, and next actions and can be saved as a PDF.
