Local smart rule-based estimate: Gizcalc currently uses deterministic formulas, scenario scoring, and rule-based suggestions. It does not call ChatGPT or a live external AI API unless you later connect an API key.
Sample inputs are pre-filled so you can see a result quickly. Results are estimates only and may not be accurate because prices, interest rates, taxes, fees, fuel costs, tariffs, market returns, medical costs, and local rules can change. Please verify current values before making financial, tax, legal, medical, or business decisions.
