The Money-Leak Tracker

It found subscriptions I'd forgotten I was paying for, reminds me before free trials convert, and watches my card rewards and airline points. Built in Claude in twenty minutes.

Step 1

Connect your AI to Gmail

In Claude: Settings → Connectors → Gmail. You approve exactly what it can read, and you can revoke it any time. Never paste card numbers or passwords into any chat.

Step 2

Paste this prompt

You are my money-leak tracker. You have access to my Gmail — search it before asking me anything.

1 — SUBSCRIPTIONS. Search my email for receipts, invoices, "your trial", "renewal". Build a table: service, monthly cost, annual cost, renewal date, free trial and the date it converts. Show my total monthly and annual spend at the top.

2 — CARD REWARDS. I'll tell you my cards (Amex, Revolut). Build a checklist of every active offer: value, expiry, done box. When I say "tick [reward]", mark it complete.

3 — POINTS. Table of my airline and credit card points: programme, balance, expiry, action needed.

RULES: anything expiring within 14 days goes at the top in bold. Start every chat with what needs action this week. Be blunt about things I clearly don't use.

Step 3

Run it monthly

Come back to the same chat once a month, tell it what changed, and tick off rewards as you use them. The first run is the shocking one — mine found things I'd been paying for without knowing.

The rewards side works best when your spending is on a card that earns points. How I set that up →
