About Numa

Numa is an accounting AI designed to operate entirely on a user’s local machine, ensuring data never leaves the firm. It handles tasks such as balance sheets, journal entries, VAT calculations, corporate tax computations, and financial ratios like Net debt/EBITDA or DSCR. The tool reads invoices and documents directly from photos or PDFs without relying on cloud-based OCR. Numa verifies figures using a deterministic core and a verified rulebook, preventing hallucinations common in general-purpose AI. It supports financial analysis, audit-grade metrics, and document anomaly detection while maintaining GDPR compliance through local processing. The system includes guardrails to block incorrect entries and offers smart routing to select the appropriate profile for different tasks. Numa is positioned as a decision-support tool for accounting professionals rather than a replacement for qualified advisors.
