Your CFO

A deterministic personal finance system designed to answer daily decisions, not merely display charts.

The problem

Finance applications often describe the past without clearly answering: can I afford this, where did I lose money, and what should I reduce?

The response

Nine specialized engines are designed to turn income, expenses, budgets, and goals into explainable diagnoses, with deterministic rules as the source of authority.

What exists today

  • Planned nine-engine architecture
  • Daily entry and custom reports
  • Lifestyle-creep detection
  • Fixed bills separated from flexible envelopes
