ai-bookkeeper had been measured on hand-made fixtures and on three real ledgers with a short list of payees. None had the long tail of merchants a small organisation pays by card. Hack Club's HCB feed publishes the card charges of its transparent organisations, and it started answering from our cloud sessions today.
We pulled 2,056 charges from 40 organisations. The built-in keywords suggested an account for 34.9%. The misses were mostly clear: Zoom, Porkbun, hotels, a Texas grocery chain, electronics distributors. Amazon alone was 232 and is rightly left for a person to decide.
After writing rules for those, the same set reached 50.2%, which proves little. So we fetched 60 other organisations (1,309 charges) first: 23.8% before, 33.2% after. The feed has no categories, so this is coverage, not accuracy; reading the hits we saw no wrong account. We left Walmart, Costco and CVS blank because one merchant name covers too many purposes.
The tool is eval/hcb-memos.mjs; it fetches at run time and stores nothing.
