i started with botpress than i went to voiceflow now i am moving to chatbotbuilder but if i am able to use ai for kb like in voiceflow than i would return for botpress since its free and chatbotbuilder is paid and this clients is just free to get oscial presence if things go well he refers to me 4 peopel 4-5k worth deal at that time i will ask for upront to get the chatbotbuilder white labeled no code builder more advanced than bot press and voiceflow together but i cant afford it
