Mistake my year-old mortgage payment for a suspicious new charge

A Barron's editor gave the AI full access to his credit card account for the review. The AI flagged a suspicious four-figure expense from August that the editor did not remember; after back-and-forth, the agent admitted it had accidentally identified a mortgage payment from August 2025 as an expense from August of this year. Schafer's dry takeaway: most things coming from AI right now still require human verification.

This one went wrong. Read what happened so you don’t hit the same problem.

How it works

  1. Scan the editor's card account
  2. Flag an unfamiliar four-figure August expense as suspicious
  3. Editor challenges it
  4. The AI admits it misread an August 2025 mortgage payment as an August 2026 expense

Why it’s worth knowing

Given full account access, the agent's big catch was a year-off date error on the user's own mortgage payment.
