1. Copy this prompt

Paste it into ChatGPT, Claude, Gemini or Grok (the free versions work), then replace the [highlighted brackets] with your details. Leave out account numbers and SSNs.

I found unauthorized [debit card / ACH / app transfer] transactions on my [BANK] account: [LIST DATES, AMOUNTS, DESCRIPTIONS]. I discovered them on [DATE]. 1) Explain, citing the CFPB, how reporting time affects my liability for unauthorized electronic transfers and what the bank must do. 2) Draft a written notice to my bank disputing each transaction. 3) List security steps to take now.

2. Follow these steps

Call your bank as soon as you spot the transaction, then follow up in writing the same day.
Ask the AI to draft a notice listing each unauthorized transaction, the date you discovered it, and that you didn't authorize it.
Change passwords and turn on alerts; ask for a new card if a card was used.
Keep a log of every call and reference number, and watch for provisional credit.

What to expect, and what to do if they say no

What to expect

Banks generally must investigate and may give provisional credit while they do.

If they say no

File a CFPB (Consumer Financial Protection Bureau, the federal consumer-finance watchdog) complaint.
Report fraud to the FTC (Federal Trade Commission, the federal consumer-protection agency) at ReportFraud.ftc.gov.

What happened when people tried it

We haven't verified a real-world example for this one yet, so it's a tool guide plus a prompt. Tried it? Tell us what happened (link below).

Why this works

The problem: People wait to see if money comes back, or report only by phone, which can weaken their protections.

How AI helps: AI can explain the reporting timelines that limit your liability, draft a clear written notice, and help you track the bank's investigation.
