Deterministic AI · receipts included

AI that shows
its math.

Ask Moxie a real money question—a Tokyo trip, a hotel splurge, next week’s groceries. The words come from an AI; every dollar is computed from your ledger, cited, and one click from its receipt.

Abstains over guessing

The deterministic demo

Three real questions on fictional data, answered under the production contract: the AI writes the sentence, code computes the numbers.

You ask

“Can I afford Tokyo in October — flight plus four hotel nights?”

Moxie answers

Yes — with . The flight is running and four nights in Shinjuku about . After October's bills and your savings rule you have , so the trip's fits.

Verified · 5/5 amounts matched the ledger

In the real app this stamp is earned, not decorative: an amount the verifier cannot match to deterministic tool output is withheld, and Moxie says so instead of guessing.

Why “deterministic AI”

The model writes.
It never does the math.

Code does the arithmetic

Every dollar in an answer comes from deterministic tools over the ledger—balances, bills, transactions, plans. The language model narrates results; it is never the source of a number.

Every figure carries a claim

Amounts ship with a citation you can open: the rows behind the figure, where each row came from, and the sum. The evidence is part of the answer, not a footnote.

No proof, no answer

A verifier checks every amount against tool output before the answer is released. A figure it cannot back gets withheld—and Moxie says so instead of guessing.
