What is my all-in monthly mortgage payment?
Principal, interest, taxes, insurance, and HOA separated.
Fixed-rate amortization plus editable monthly cost assumptions.
OzzzAI calculator
Ask a calculation the way you would ask a person.
Ozzz turns natural language into code-backed calculations, then keeps the result, assumptions, formulas, and caveats visible.
The first screen stays conversational. The detailed work appears when it matters: inputs, assumptions, formulas, code-backed method, checks, and caveats.

Why conversational
Real calculations rarely fit a single form.
You can start with an incomplete question. Ozzz can calculate from what you gave it, state what it assumed, and let you revise the inputs in the next message.
Audio stays useful on mobile: Ozzz can speak the short answer while the screen keeps the full work available for inspection.
The point is not to hide math inside a chat bubble. The point is to make the calculation inspectable without making you operate a spreadsheet first.
Examples
Questions this page is built for.
Each example is meant to become a transparent calculation, not a model-only guess.
How many calories should I eat to lose 1 lb per week?
Maintenance estimate, target calories, and macro ranges.
BMR/TDEE formulas with activity and deficit assumptions.How likely is this project to finish under budget?
Scenario estimate with uncertainty and sensitivity notes.
Monte Carlo style simulation when ranges are provided.Method
The useful parts stay visible.
Ozzz is designed to show the answer, the assumptions, the method, and the caveats. For planning questions, it should make the calculation easier to revise, not harder to trust.
Inputs
Numbers you supplied are preserved as exact facts. Missing variables are called out as assumptions.
Formulas
Standard formulas and component outputs are shown when they help explain the result.
Code-backed work
For serious calculations, Ozzz uses code-backed computation instead of mental arithmetic.
Revision
Ask “what if the APR is lower?” or “change activity to light” and continue from the prior calculation.
Start
Open Ozzz in calculator mode.
Calculator mode starts monolingual, keeps assistant audio on, and turns off practice-language translation by default. You can change settings later.
