Most help-desk search still matches words. Ask "what's the cost?" and you get articles that happen to contain "the". And most chat platforms bill per seat and per resolution, so the bill grows every month.
So we built our own, and it runs support for our own brands today. The AI reads your docs and answers the question that was asked. Anything it can't answer goes to a person, with a Solved button and a five-star rating after every chat.
