Experiment lab
Change the inputs.
See what changes.
Set a scenario. Compare it with a reference. Let a small AI model suggest another experiment, then see the result calculated from the equations.
Historical research snapshots, not live prices or forecasts. Everything runs in your browser.
What if borrowing costs change?
02 / Calculate the result
Monthly principal and interest
03 / Try another experiment
What could change the answer?

What the AI does, and what it does not do
A small regression tree learns from 441 scenarios calculated on this device. It uses those examples to shortlist experiments. Every result on a suggestion card is recalculated with the exact model equations before it is shown.
It learns how this calculator behaves, not what markets or lenders will do. These scenarios are not forecasts, probabilities, quotes or recommendations. Importance depends on the tested input ranges.
No AI service is called. Inputs stay on this device. AI API spending: $0.
