Amazon Lex – Conversational interfaces for your applications

With Amazon Lex, you can build, test, and deploy your chatbots directly from the Amazon Lex console. Lex enables you to easily publish your voice or text chatbots to mobile devices, web apps, and chat services such as Facebook Messenger (with Slack and Twilio integration coming soon). Once published, your Amazon Lex bot processes voice or text input in conversation with your end-users. Amazon Lex is a fully managed service so as your user engagement increases, you don’t need to worry about provisioning hardware and managing infrastructure to power your bot experience.
