Arithimatic Agent

Your newest staff member — available 24/7

The Agent understands accounting. It queries your standards library, reasons over your documents, and surfaces defensible, traceable answers — not hallucinations.

Natural language queries against ASC 842, IFRS 16, and all major accounting standards.
Source-cited responses — every answer links to the exact document clause or standard section.
Proactive alerts when the Agent detects anomalies, inconsistencies, or missing data.
Full conversation history preserved in your audit trail — every query is logged and reviewable.
