Search for the bot you want to add. At the time of this writing, there are about a dozen bots available, with more being added every day. Chat bots are available for customer service, news, ordering, and more, depending on the company that releases it. For example, you could get news from the CNN bot and order flowers from the 1-800-flowers bot. The process for finding a bot varies depending on your device:[1]
A virtual assistant is an app that comprehends natural, ordinary language voice commands and carries out tasks for the users. Well-known virtual assistants include Amazon Alexa, Apple’s Siri, Google Now and Microsoft’s Cortana. Also, virtual assistants are generally cloud-based programs so they need internet-connected devices and/or applications in order to work. Virtual assistants can perform tasks like adding calendar appointments, controlling and checking the status of a smart home, sending text messages, and getting directions.
Students from different backgrounds can share their views and perspectives on a specific matter while a chatbot can still adapt to each one of them individually. Chatbots can improve engagement among students and encourage interaction with the rest of the class by assigning group work and projects - similarly to what teachers usually do in regular classes.
By 2022, task-oriented dialog agents/chatbots will take your coffee order, help with tech support problems, and recommend restaurants on your travel. They will be effective, if boring. What do I see beyond 2022? I have no idea. Amara’s law says that we tend to overestimate technology in the short term while underestimating it in the long run. I hope I am right about the short term but wrong about AI in 2022 and beyond! Who would object against a Starbucks barista-bot that can chat about weather and crack a good joke?
There are several defined conversational branches that the bots can take depending on what the user enters, but the primary goal of the app is to sell comic books and movie tickets. As a result, the conversations users can have with Star-Lord might feel a little forced. One aspect of the experience the app gets right, however, is the fact that the conversations users can have with the bot are interspersed with gorgeous, full-color artwork from Marvel’s comics. 

Indeed, this is one of the key benefits of chatbots – providing a 24/7/365 presence that can give prospects and customers access to information no matter when they need it. This, in turn, can result in cost-savings for companies that deploy chatbots, as they cut down on the labour-hours that would be required for staff to manage a direct messaging service every hour of the week.
As IBM elaborates: “The front-end app you develop will interact with an AI application. That AI application — usually a hosted service — is the component that interprets user data, directs the flow of the conversation and gathers the information needed for responses. You can then implement the business logic and any other components needed to enable conversations and deliver results.”
This kind of thinking has lead me to develop a bot where the focus is as a medium for content rather than a subsitute for intelligence. So users create content much as conventional author, (but with text stored in spreadsheets rather than anywhere else). Very little is expected from the bot in terms of human behavious such as “learning”, “empathy”, “memory” and character”. Does it work?
This machine learning algorithm, known as neural networks, consists of different layers for analyzing and learning data. Inspired by the human brain, each layer is consists of its own artificial neurons that are interconnected and responsive to one another. Each connection is weighted by previous learning patterns or events and with each input of data, more "learning" takes place.
Founded by Pavel Durov, creator of Russia’s equivalent to Facebook, Telegram launched in 2013 as a lightweight messaging app to combine the speed of WhatsApp with the ephemerality of Snapchat along with claimed enhanced privacy and security through its use of the MTProto protocol (Telegram has offered a $200k prize to any developer who can crack MTProto’s security). Telegram has 100M MAUs, putting it in the second tier of messaging apps in terms of popularity.
We then ran a second test with a very specific topic aimed at answering very specific questions that a small segment of their audience was interested in. There, the engagement was much higher (97% open rate, 52% click-through rate on average over the duration of the test). Interestingly, drop-off went wayyy down there. At the end of this test, only 0.29% of the users had unsubscribed.

Chatfuel is a platform that lets you build your own Chatbot for Messenger (and Telegram) for free. The only limit is if you pass more than 100,000 conversations per month, but for most businesses that won't be an issue. No understanding of code is required and it has a simple drag-and-drop interface. Think Wix/Squarespace for bots (side note: I have zero affiliation with Chatfuel).

Jabberwacky learns new responses and context based on real-time user interactions, rather than being driven from a static database. Some more recent chatbots also combine real-time learning with evolutionary algorithms that optimise their ability to communicate based on each conversation held. Still, there is currently no general purpose conversational artificial intelligence, and some software developers focus on the practical aspect, information retrieval.
