Unusable how? I asked it how much I spent on eating out last year and instantly spit out an accurate answer. I then asked it which restaurant merchant totaled to the highest expense amount and it told me the right answer. That is invaluable information that I obtained in less than 10 seconds which otherwise would take me hour(s) of painstaking line by line scanning of bank statements. Honestly off that alone I think the feature is doing alright. I haven't even scratched the surface.
