Track your card spending in a Google Sheet from bank alerts

Turn your bank's card alerts into a spending log in a Google Sheet you own. Every purchase becomes a row as it happens, the same way every time.

Ask your AI assistant:

“TrackerHacker my spending”

How it works

In Claude, ChatGPT or Gemini, type TrackerHacker my spending.
The first time, your assistant asks you to connect TrackerHacker. Sign in with Google and tap Allow. That's your sign-up too: there's no separate account to make.
Your assistant makes the sheet in your own Google Drive (the ready-made Transactions sheet) and tells you what's left to do.
Turn on your bank's email alerts for card purchases (most banks offer them in their app), then forward them to your TrackerHacker address with a Gmail filter. Monzo, Starling, Mercury and Revolut Business send each transaction straight to the sheet instead, with no email.
From then on TrackerHacker fills the sheet by itself, day and night, even when your assistant isn't open. Ask your assistant about it any time.

Date: The day it happened, in your timezone.
Merchant / Description: Who was paid or paid you, e.g. Trader Joe's
Amount: -12.50 for money out, 12.50 for money in
Currency: ISO code such as USD; blank means your usual currency.
Account: Which card or account it was, e.g. "Visa 1234".
Category: A spending category. Open text: each sheet template sets its own list of categories.
Type: debit: money out; credit: money in; transfer: between your own accounts.
Transaction status: planned: money you mean to spend, added ahead; pending: the bank hasn't settled it yet; posted: settled. Blank means posted.
Bank reference: The bank's id for the transaction, when the message has one. The same on its pending and posted alerts, so a later alert updates the row.

Each bank words its emails differently. The first time an alert arrives, your assistant teaches TrackerHacker to read it, and every later one is read the same way.
Your phone can ask you to pick a category for each new purchase, and the sheet's formulas do the totals.
Ask for a monthly budget instead of a list and the sheet shows spending by category against your plan.
Fixed rules called hacks write each row, not AI guesses, so the same email always makes the same row.
TrackerHacker keeps none of your mail: each message is read once, and the rows live only in your own sheet.
