Chatbot, when it plays its role as a virtual representative of an enterprise, is widely used by businesses outside of the US, primarily in the UK, The Netherlands, Germany and Australia. Additionally, the usage of this term is quite popular amongst amateur AI enthusiasts willing to spend vast amounts of time on their own intelligent creations (with diverse outcomes).
But Zuckerberg is just getting started. And he is doubling down on his plan to monetize Facebook by delving into the foggy world of artificial intelligence (AI) in order to have computer software programs called bots, take over sales and customer service functions on Facebook's Messenger platform. This has profound consequences not only for Facebook’s bottom line, but for marketers as well.
So now, for the fun part, here’s a bot for you to make your everyday conversations with friends more fun, since Messenger is all about conversations, right? Never miss a chance to create an appropriate meme to make the receiver crack up with humour, and astonished with the speed you reverted with the meme. Ping the bot, look among popular memes to use, and customise the text yourself.
There are two types of chatbots available: those that function based on rules and those that use artificial intelligence (A.I.). Chatbots that function based on rules are much more limited than those that work with A.I. because they only respond to specific commands. Hence, they require a great deal of programming in order to be an effective tool. Chatbots tools that are powered by artificial intelligence are more dynamic because they respond to language, and don’t require specific commands. They learn continuously from the conversations they have with people and can help fulfill an array of tasks without a monumental amount of programming.
Think of a message thread as the place where you connect and interact with your users. Build just one bot, and your experience is available on all platforms where Messenger exists, including iOS, Android, and web. It also removes the friction of your users having to download one more app, on top of all the apps they already have and may not use, given Messenger is now used by 900 million people every month.

Efforts by servers hosting websites to counteract bots vary. Servers may choose to outline rules on the behaviour of internet bots by implementing a robots.txt file: this file is simply text stating the rules governing a bot's behaviour on that server. Any bot that does not follow these rules when interacting with (or 'spidering') any server should, in theory, be denied access to, or removed from, the affected website. If the only rule implementation by a server is a posted text file with no associated program/software/app, then adhering to those rules is entirely voluntary – in reality there is no way to enforce those rules, or even to ensure that a bot's creator or implementer acknowledges, or even reads, the robots.txt file contents. Some bots are "good" – e.g. search engine spiders – while others can be used to launch malicious and harsh attacks, most notably, in political campaigns.[2]

According to Richard Wallace, chatbots development faced three phases over the past 60 years. In the beginning, chatbot only simulated human-human conversations, using canned responses based on keywords, and it had almost no intelligence. Second phase of development was strictly associated with the expansion of Internet, thanks to which a chatbot was widely accessed and chatted with thousands of users. Then, the first commercial chatbot developers appeared. The third wave of chatbots development is combined with advanced technologies such as natural language processing, speech synthesis and real-time rendering videos. It comprises of chatbot appearing within web pages, instant messaging, and virtual worlds.
However, web based bots are not as easy to set up as a stand-alone chatbot application. Setting up a web-based chatbot requires at least minimal experience with HTML, JavaScript and Artificial Intelligence Markup Language (AIML). Additionally, any sort of “fancy” features, such as Text To Speech, or an animated avatar, would have to be created and integrated into your chatbot’s page, and certain features, such as voice recognition, are either unavailable, or are severely limited.
Last, but not least coming in with the bot platform for business is FlowXO, which creates bots for Messenger, Slack, SMS, Telegraph and the web. This platform allows for creating various flexibility in bots by giving you the option to create a fully automated bot, human, or a hybrid of both. ChatBot expert Murray Newlands commented that "Where 10 years ago every company needed a website and five  years ago every company needed an app, now every company needs to embrace messaging with AI and chatbots."
Interface designers have come to appreciate that humans' readiness to interpret computer output as genuinely conversational—even when it is actually based on rather simple pattern-matching—can be exploited for useful purposes. Most people prefer to engage with programs that are human-like, and this gives chatbot-style techniques a potentially useful role in interactive systems that need to elicit information from users, as long as that information is relatively straightforward and falls into predictable categories. Thus, for example, online help systems can usefully employ chatbot techniques to identify the area of help that users require, potentially providing a "friendlier" interface than a more formal search or menu system. This sort of usage holds the prospect of moving chatbot technology from Weizenbaum's "shelf ... reserved for curios" to that marked "genuinely useful computational methods".
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. 
Streamchat is one of the most basic chatbot tools out there. It’s meant to be used for simple automations and autoresponders, like out-of-office replies or “We’ll get back to you as soon as we can!” messages, rather than for managing a broader workflow. It’s quick to implement and easy to start with if you’re just dipping your toes into the chatbot waters.
