I tested 90% of the Chatbots in Appsumo, current and past. This chatbot is among the bests. First, it is stable from the start, no serious bug, so this means they can ship new features fast, not having to correct much. Second, they take into account seriousely the suggestions and adjust fast. Third, the quality of the output is among the best.
What frustrates me in the deal, is the restrictions in the number of bots. This excludes agency option. I would suggest they allow the use of unlimited bots when you use your own key.
