A data analyst you can interrogate
A data analyst you can interrogate. It does not just answer; it investigates. Ask "why did revenue jump?" and it breaks the change across every dimension into a waterfall that reconciles to the dollar. Ask for cohort retention or an anomaly scan and it computes those live too, against a 125,000-row warehouse running on SQLite-in-WebAssembly in your browser. A pixel crew of four talks through each step. A public 35-question eval shows the browser engine matches its Python twin to the cent. Paste your API key and a live LLM takes the planner's seat, with guardrails that keep it from ever writing raw SQL.
