What the Gemini AI Auditor in Expentify Actually Looks At
By Nasim Farhan, Founder, Expentify · May 19, 2026 · 5 min read
A straight description of what happens when you run an AI audit in Expentify: what data goes to Gemini, what it's asked to find, and what kind of suggestions come back — no invented statistics, just how the feature works.
A quick honest note before anything else: you may see marketing copy elsewhere (including, previously, on this page) throwing around specific-sounding numbers like "22% higher savings velocity." That number wasn't from a real study — it was a placeholder that read like a stat. Here's what the AI Auditor actually does instead, described plainly.
When you run an audit, Expentify sends your wallets and transactions to our server, which forwards them to Google's Gemini model (currently `gemini-3.5-flash`) along with a prompt describing what to look for. Your name and email address are not included. You need to be signed in to run this — the request is tied to your account, not sent anonymously.
What it's actually asked to find
Unless you ask it something specific, the prompt asks the model to look at these things in your data:
Repeated small charges that might be subscriptions you've forgotten about — the kind of $8-15 monthly charge that's easy to miss scrolling through a bank statement, but obvious once transactions are grouped by merchant and amount.
Category concentration — whether a disproportionate share of a month's spending landed in one category, which is more useful as a prompt to go look at why than as a verdict on whether that was good or bad spending.
Idle cash sitting in a non-interest-bearing wallet, flagged as an opportunity cost worth considering, not a directive to move it.
Balances to watch, such as a negative wallet or a high card or loan balance.
What comes back, and its real limits
The response is a written summary in plain language, not a formal financial plan. It's a language model reading your transaction categories and amounts — it doesn't know your income stability, your other debts outside the app, your risk tolerance, or anything about your actual life. Treat it the way you'd treat a knowledgeable friend glancing at your spreadsheet for five minutes: a reasonable starting prompt for your own thinking, not financial advice, and not a substitute for talking to an actual advisor about anything that matters — taxes, debt restructuring, or investment decisions especially.
