Use case overview

Claude Code pulled transactions across credit cards, flagged recurring charges, and drafted cancellation emails, recovering $700.

Reported experience

  1. What they did

    Molly Cantillon gave Claude Code access to her emails, bank accounts, investments and other personal data. It pulled transactions across all her credit cards and flagged recurring charges such as gym memberships and Netflix. For each one it asked whether she used it. If she said no, it drafted an email asking the company to cancel.

  2. How it went

    She says she got $700 back on day one, against a $20 a month Claude Code cost. The $700 is her own claim, and the article doesn't break it down.

  3. Worth knowing

    The setup relies on handing an AI broad access to email and bank data. An expert quoted in the article advises strong authentication, limited permissions and confirmation before any money moves.

Example prompts

Try with Claude Code
Connect to my bank and credit card statements or export transactions, scan the last 6 months for recurring subscription charges, and list every one with amount and frequency. Flag any I likely don't use and draft cancellation emails for each, but pause and show me the list and drafts before sending anything.
