Audit credit card use for wrong-card charges and missed benefits
Grok Bot read posted transactions on three cards via a Plaid-connected app to check card choice for dining, Amazon and travel, and unused benefits.
Done withGrok Bot
- What they did
- User set up Grok @bot with Captain as the interface, Spendy pulling posted transactions via Plaid on Amazon, Sapphire and Platinum cards, and Researchy using Grok CLI 4.6 live search on Chase/Amex sites for current benefits. Captain combines the data to flag wrong-card charges on dining/Amazon/travel and unused credits like Sapphire travel, DoorDash, Resy and Lululemon, then outputs a named recap.
- How it went
- Delivers a monthly recap of mismatches and left-on-table benefits. Source states no dollar results or savings figures.
- Worth knowing
- Runs monthly on Grok @bot; agents never post charges or apply for cards without explicit user approval.
