ChatGPT prompt to find subscriptions draining your account

TL;DR

A copy-paste ChatGPT prompt to scan 90 days of transactions, spot recurring charges, rank yearly cost, and decide keep, downgrade, or cancel — with a verify step.

By the AI Money Playbooks editorial team · Updated Oct 15, 2026 · 3 min read · Educational, not financial advice

Recurring charges hide in plain sight: streaming stacks, forgotten trials, "free" apps that converted, cloud storage you already get elsewhere. You do not need a fancy app to start. Export 90 days of transactions, redact account numbers, and ask ChatGPT (or Claude, Gemini, or Grok) to list likely subscriptions by yearly cost.

Educational only. Not financial advice. AI invents confident mistakes — re-check every merchant on your statements before you cancel anything.

What you need

CSV or copy-paste export from checking cards and payment apps (Venmo/PayPal/Cash App if you use them for subscriptions).
10 minutes to redact: delete account numbers, balances, and your address.
A simple Keep / Downgrade / Cancel column in a sheet.

Copy-paste prompt

From these 90 days of transactions [PASTE redacted CSV or lines], identify charges that look recurring (same merchant, similar amount, roughly weekly/monthly/yearly). Output a table: Merchant | Amount | Frequency guess | Annual cost | Last charge date | Confidence (high/med/low). Sort by annual cost descending. Show the combined annual total. Do not invent merchants that are not in the data. Flag possible duplicates (same service under two brand names).

Second prompt: decide

Here is my subscription table [PASTE]. Usage last month: [SERVICE: times used]. Rank each Keep / Downgrade / Cancel using cost per use. Show the math. For Downgrade, suggest what cheaper tier or free alternative to evaluate (no affiliate pitches). Total potential monthly and annual savings if I follow Cancel + Downgrade — label it illustrative.

Verify (do not skip)

Annual cost = monthly × 12 (or weekly × 52). Recompute the top five by hand.
Open each merchant in your bank app before canceling — AI sometimes merges different services.
Write down confirmation numbers. Check the next statement.

Cancellation script (short)

"I want to cancel [SERVICE] effective today. Please confirm no further charges and email a confirmation number. I'm not interested in retention offers above $[MAX]."

FAQ

Is it safe to upload my bank statement to ChatGPT? Remove account numbers, your name and address first, and use a tool with clear privacy controls. A CSV with only date, merchant and amount is enough for this prompt.

Can AI cancel subscriptions for me? No. It finds and ranks recurring charges and drafts cancellation scripts; you cancel through each merchant and confirm on your next statement.

How far back should I export transactions? 90 days catches monthly charges; 12 months catches annual renewals.
