The financial operating system that quietly watches over your money.

Firdona connects to your real accounts and Sterling, its AI layer, narrates what’s actually happening in your spending — computed first, stated plainly, never invented.

Facts, not guesses

Sterling never computes a number itself. Every figure it narrates — safe spending, a price increase, a spending pattern — is calculated first in plain code from your real transactions, then only phrased. Sterling can't invent a number it wasn't given.

Real bank connections

Link a real checking, savings, credit, or loan account through Plaid. Balances and transactions sync automatically — no manual entry, no spreadsheets.

Goals, calendar, purchase intelligence

Live goal pacing that updates with every purchase, a calendar of upcoming bills detected from your own history, and a buy/wait/avoid verdict — grounded in your real budget — before you spend.
