A monthly budget in Google Sheets that fills itself

A Google Sheets budget that fills itself from your bank alerts: spending by category against what you plan, without typing in purchases.

Ask your AI assistant:

“TrackerHacker my budget”

How it works

In Claude, ChatGPT or Gemini, type TrackerHacker my budget.
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.
Your bank's card alerts, forwarded to your TrackerHacker address with a Gmail filter. Each purchase becomes a row, and the budget tab adds them up by category.
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.

You set what you plan to spend on each category in the sheet. It's your sheet, so you can change the formulas too.
Ask your assistant "am I over budget?" and it answers from the sheet.
Prefer 50/30/20? Ask for that and the sheet splits needs, wants and savings instead.
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.
