Alexa is officially a chatbot. Yesterday, Amazon began rolling out a new feature on iOS that enables users to type their requests to Alexa and see responses on the screen. This is yet another update Amazon has made this year in its Alexa mobile app as the company attempts to extend the voice assistant’s utility beyond the home. It will also be welcomed by many users as a big convenience since Alexa services will now be available without making a sound. Others will wonder why a chatbot is a necessary update.
