As of 13 August 2026, AI can only partly spot suspicious transactions in your bank account.
Most people should hand this to a purpose-built tool.

Second choiceA chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.
How to actually do it
- Open your bank's official app or website and export the relevant transactions as a CSV or spreadsheet.
- Remove passwords, full account numbers, card numbers, sort codes, security codes and any other unnecessary personal data, while keeping dates, amounts, payment descriptions and transaction types.
- Add brief notes beside transactions where you already know the context, such as rent, a subscription, a shared household payment or a transfer between your own accounts.
- Paste the redacted data and the copyable prompt into ChatGPT, Claude or Gemini, and ask it to produce the flagged-transaction table and action list.
- Compare every flagged entry with your receipts, subscription records, messages and transfers from other accounts, correcting any context the model missed.
- For any payment you do not recognise or did not authorise, contact your bank through its official app, website or telephone number immediately, rather than relying on the chatbot's conclusion.
- Save the bank's case reference and the checked transaction list, then remove the uploaded financial data from the chatbot service if its controls allow it.
Prompt
Analyse the transaction data below for possible suspicious activity. Treat this as a triage exercise, not a fraud determination and not professional advice. Do not invent missing facts, merchant identities or explanations. First identify duplicate payments, unusual amounts, unusual timing, new or unfamiliar merchants, recurring payments that changed, cash withdrawals, transfers, card payments and transactions outside my normal pattern. For each flagged transaction, give the date, amount, description exactly as supplied, the reason it was flagged, and a confidence level of low, medium or high. Separate likely ordinary explanations from items I should check urgently. Do not tell me that a transaction is definitely fraudulent. Do not ask me to share passwords, full account numbers, card numbers, sort codes or security codes. Tell me what evidence I should compare, such as receipts, subscriptions, messages or another account. End with a short action list: what I should check myself, what I should contact the bank about immediately, and what information I should have ready.

What it gets wrong
- AI cannot see your bank's live fraud signals, device history, payee records or account security events.
- AI cannot establish that an unfamiliar payment is fraudulent from a transaction line alone.
- AI can miss fraud that resembles your normal spending or flag legitimate payments that look unusual.
- AI cannot contact your bank, freeze your card or make a reimbursement decision for you.
- Uploading transaction data creates a privacy risk, even when you remove obvious account and card details.
What caps this at PARTLY: stakes of error, private data access and judgement under ambiguity.

FAQ
- Can ChatGPT check my bank transactions for fraud?
- It can scan a redacted transaction export and flag patterns that deserve checking, such as duplicates, unusual amounts or unfamiliar merchants. It cannot confirm fraud, access your bank's live security information or replace contacting your bank.
- Is it safe to upload my bank statement to AI?
- Only share the minimum redacted data needed, and never share passwords, full account numbers, card numbers, sort codes or security codes. Financial data is sensitive, so check the chatbot's data controls and delete the upload when possible.
- What should I do if I see a suspicious transaction?
- Check it against your receipts, subscriptions and transfers, then contact your bank immediately through an official channel if you did not authorise it. Do not wait for an AI result before reporting a payment that may be fraud.
- Can AI tell me whether a bank payment is fraudulent?
- No. It can prioritise transactions for investigation, but it cannot establish who authorised a payment or make the bank's fraud and reimbursement decision. This is not professional advice; a serious case needs your bank's fraud team.
