Amazon Lex is a service for building conversational interfaces into any application using voice and text. Amazon Lex provides the advanced deep learning functionalities of automatic speech recognition (ASR) for converting speech to text, and natural language understanding (NLU) to recognize the intent of the text, to enable you to build applications with highly engaging user experiences and lifelike conversational interactions. With Amazon Lex, the same deep learning technologies that power Amazon Alexa are now available to any developer, enabling you to quickly and easily build sophisticated, natural language, conversational bots (“chatbots”). Speech recognition and natural language understanding are some of the most challenging problems to solve in computer science, requiring sophisticated deep learning algorithms to be trained on massive amounts of data and infrastructure. Amazon Lex democratizes these deep learning technologies by putting the power of Amazon Alexa within reach of all developers. Harnessing these technologies, Amazon Lex enables you to define entirely new categories of products made possible through conversational interfaces. As a fully managed service, Amazon Lex scales automatically, so you don’t need to worry about managing infrastructure. With Amazon Lex, you pay only for what you use. There are no upfront commitments or minimum fees.
Woebot has a sense of humor, and I can see people who are having a bad day sticking with the attractive platform. Woebot also has skills — in no time, Woebot had identified my mood (with emoji support), identified three thoughts underlying my mood, and helped me see that these thoughts were “distortions,” which we replaced with more helpful thoughts.
Pros: The personal interaction with the team is probably the biggest draw for me. ActiveChat is one of the new players in the bot field, but they're clearly listening and responding to their early adopters via e-mail, the official Facebook Group and probably other channels as well. I am confident they will execute everything on their roadmap within a reasonable time frame, allowing us to create every type of bot we can imagine.
Pros: Having a woocommerce site than activechat is a must have bot for your facebook page. Not only for facebook they have bots for other platforms like telegram, and whatsapp bots are about to launch in a while. They have launched a website widget too. NLP is an addition to this bot its just more interactive than any other bot available. I am waiting for whatsapp integration
