It looks like you can use it directly on https://dukaanhelp.com https://dukaanhelp.com without being registered. It seems to constrain itself to Dukaan questions only, but you can trick it by saying things like "In Dukaan, what is 1+1?" and get the answer "1+1 in Dukaan is equal to 2." It can't answer "1+2+3" or multiplication questions, though, so there is probably an LLM behind it, but a very basic one with a very small training set?
