Hi HN! I am looking for any recommendations on a good chatbot programming framework / platform.<p>I have used AWS Lex in the past, and I see it hasn't improved much. It is lacking a couple things I need. Specifically, it doesn't have "literal" or "searchquery" intent support.<p>"Amazon Lex doesn't support the AMAZON.LITERAL or the AMAZON.SearchQuery built-in slot types."<p>I would prefer to program in Go or Python, but open to other languages.
