The ability of creating bots that can interact with customers without any hassle or difficulty what so ever! It’s very user friendly as well which makes things easier when compared to other platforms like Facebook Messenger etc., I don't have anything negative about this product but if there are some features they could improve upon then surely would be great.
We used spectrm to create our first bot called "MyBot” where we were able to communicate with people through voice messages using text-to-speech technology along with images & videos too.
