Core Architecture

The Fundamental Hijin Workflow

Four disciplined stages that ensure private inputs result in mathematically verified outputs.

1

Understand

Parses documents, invoices, structured tables, and workspace context locally without cloud dependencies.

2

Reason

Combines conversational intelligence with specialized domain models trained for financial structures.

3

Verify

Validates numbers with fixed 28-digit precision decimal math. Prevents rounding drift and floating-point errors.

4

Create

Generates audit-ready reports, forensic reconciliation tables, and executive briefing artifacts.
