What they did
A trading card collector built a team of Grok Bots: one hunts Pokémon Center drops, one watches for Disney Lorcana drops and restocks, and "Carl the Card Researcher" checks prices. Send Carl a listing or a photo and it tells you whether the price is real, with the recent sold median, the market price and the gap after fees.
How it went
He says he built it because he hated looking up card prices across different TCG sites himself.
