ai-bookkeeper suggests an account for a bank line from built-in keywords. To see how they do on text nobody wrote them against, we read the card charges of 40 transparent Hack Club HCB organisations (page 8 of the public feed, fetched at run time, nothing copied into the repo): 392 charges.
The keywords suggested an account for 48.2%. The biggest single miss after Amazon (64, left alone on purpose: supplies, inventory or software) was one local shop, "Star Pizzeria", 38 charges. The restaurant rule matched pizza, not pizzeria. Adding it, plus robotics parts shops (AndyMark, MaxBotix, Prusa, SparkFun) and ice-cream chains, lifts coverage to 67.6% (a parallel run landed the first pass at 64.3%; this one adds the rest), though now tuned on the same page, so that number overstates what a fresh page would show. There are no labels in the feed, so "right" stays unmeasured. The README keeps the log.
