The ease of use, the documentation is excellent! It's easy to get started quickly even without any programming experience. I like how you can build bots from scratch or copy-paste existing ones in minutes. Also, it's free (as in beer) which makes me feel better about using their product. There isn't much we dislike so far but maybe there should be some features added sooner than later. We're building an AI assistant bot that will respond to customer support tickets and help our customers solve problems faster.
