What they did
With no photos of her own of the car, she uploaded the photos Sixt had sent to Claude. The AI pointed to identical timestamps as a "critical finding" and suggested accusing the rental company of fraud and disputing the charge.
How it went
The Points Guy reports that the letter failed: the timestamp argument didn't hold up.
Good to know
Photograph the car at pickup and return. And be wary when AI draws strong conclusions from weak evidence.
