The Evolution of chatbots dates to Joseph Weizenbaum’s ELIZA program, which is released in 1964. Weizenbaum, a professor at the Massachusetts Institute of Technology(MIT), named the program Eliza, a play about a Cockney girl who learns to speak and think like an upper-class lady. Eliza convinced many users that they were having a conversation with a human being, not a machine at all.

Eliza processed natural language as an input and, as an output. By 1967, using Carl Rogers principles of the psychology of empathy, Weizenbaum managed to develop a program that could discuss with a human being in a comprehensible way.

One could argue, this was the worlds very first chatbot.

The Followers of Eliza

There are very few of chatbots that have made headlines in the history.


A popular and clever chat bot. According to Google Analytics, There are more then 17 million people used in last year and over 1.5 billion interactions.


It collects data from the artificial interactions from its users. Once the conversation is finished it stores all data in its database and uses it later to simulate artificial intelligence.

Cleverbot comes very close to passing the Turing test Techniche 2011, IIT Guwahati, India.

WeChats` Xiaoice:

Another old it’s an artificial intelligence program designed to chat with people. Many people from China is having full-fledged communications Xiaoice.

Xiaoice is an artificial intelligence bot programmed to behave like a 17 years old girl, empathetic, witty, and sometimes divisive.

There are also Virtual assistants, designed for business purpose,

Virtual Assistants “are programmed to provide set responses to particular events and requests. It may answer an incoming telephone call with a standard greeting followed by a menu or other information describing available choices and sub-menus available to the user together with the appropriate access method”. McAllister, A.

Examples of some popular Virtual Assistants,

Siri by Apple:

If you have an iPhone, iPad or Apple watch you have probably met Siri. He is an interesting little fellow, sometimes useful, sometimes humorous and other times, a sarcastic little so and so.

“A voice-driven assistant that talks back to you — invoked by long-pressing the iPhone or iPad home button — and proactively recommends actions to take” (Newman, 2016)

Some questions asked to Siri, and answers are hilarious,

What is your best pick up line?

Siri is a real charmer here. “Is your name Bluetooth? Because I am really feeling a connection.”, “Like the ideal vacuum, you’re the only thing in my universe” and “You auto-complete me”.

Do you believe in God?

“That’s a topic for another day, and another assistant”.

Knock, Knock

“Knock, knock. Who’s there? Britta. Britta who? Britta, I don’t do knock-knock jokes”.

Jarvis by Mark Zuckerberg (Facebook): 

It is described by its creator as kind of like Jarvis in ‘Iron Man’.(Mark Zuckerberg, M. 2016) Because Jarvis is a home assistant it has been programmed such way that it could control Zuckerberg’s house hold items from the toaster to house lights.

Zuckerberg plans to develop more capabilities into Jarvis and has invited the people for more ideas. He also said that he would like to explore teaching Jarvis how to learn skills itself rather than having someone teach it. An Android app to control Jarvis is in the works, as is making the AI available publicly.

Zuckerberg also said in a post, “For assistants like Jarvis to be able to control everything in homes for more people, we need more devices to be connected and the industry needs to develop common APIs and standards for the devices to talk to each other.”

Alexa by Amazon:

Amazon calls it a smart speaker. This is Amazon’s virtual assistant that powers the company’s first-party Echo speakers.

Alexa is able to tell you about the local weather, check calendar appointments, control smart home devices, and so much more.


Smart speakers are the most traditional form factor you’ll find Alexa on, but the AI has also made its way to smartphones, headphones, and even some smartwatches.

Amazon updates Alexa all the time to perform it smarter than the day before, meaning that it’s constantly evolving and emerging.

Cortona By Microsoft:

Cortana is a virtual assistant created by Microsoft for Windows 10, Windows 10 Mobile, Windows Phone 8.1, Invoke smart speaker, Microsoft Band, Surface Headphones, Xbox One, iOS, Android, Windows Mixed Reality, and Amazon Alexa.

Cortana can set reminders, recognize natural voice without the requirement for keyboard input, and answer questions using information from the Bing search engine.

Google’s version of Amazon’s Alexa, Apple’s Siri and Microsoft’s Cortana is Google Assistant. It has made incredible progress since its 2016 launch and is one of the most superior and dynamic of the assistants out there.

Google has spread the Assistant far and wide, not only on its own hardware but through partnerships with other companies that see Google Assistant in an immense range of devices, from fridges and headphones to speakers and cars.

Here’s how Google Assistant works and what you need to know about Google Assistant’s Artificial intelligence.

What is Google Assistant?

Google Assistant is Google’s voice assistant. When it launched, Google Assistant was an extension of Google Now, designed to be personal while expanding on Google’s existing “OK Google” voice controls.

Originally, Google Now smartly pulled out relevant information for you. It knew where you worked, your meetings and travel plans, the sports teams you liked, and what interested you so that it could present you with information that mattered to you.

Google has long killed Google Now, but Assistant lives in the same space, fusing these personalized elements with a wide range of voice control. Google Assistant supports both text or voice entry and it will follow the conversation whichever entry method you’re using.

What It Can Do?

While searching for a website or finding a vacation destination, Google Assistant is always there for you. Google assistant plays a very important role in making your life smarter and easier.

In this modern technological era, people are very much dependent on smart technology. Google assistant is a major initiative taken by Google to make artificial intelligence-human relationships much better.

You can understand the magical power of “Hey, Google” just by speaking in front of any smart voice-enabled devices. It can solve your daily problems such as a hair salon appointment or even make a call.
