If you're in the market for the best chatbot, then read on because we've done the heavy lifting in terms of research so you don't have to.

Sundar Pichai, the CEO of Google, said it back in 2016:

Over time, the computer itself—whatever its form factor—will be an intelligent assistant helping you through your day. We will move from mobile-first to an AI-first world.”

This prediction is slowly becoming a reality as Artificial Intelligence (AI) and Machine Learning technologies are seeing mass-scale adoption. At home it’s Amazon’s Alexa, on the go it’s Apple’s Siri and, on the web there are chatbots. 

Chatbots are slowly becoming the norm in business-to-consumer because most people actually prefer to send a message than speak on the phone. Besides, Salesforce reports, 9 out of 10 consumers will use a chabot instead of a form if it’s available. So, it’s no wonder that  80% of enterprises will deploy chatbots in 2020. Many experts also think that chatbots are crucial for a great user experience.

Call centers, websites, and mobile apps are no longer the only means of interaction with brands. Chatbots are fast becoming a business imperative for businesses that want to engage with their customers. Online chat through chatbots has grown faster than any prior channel.” —Eileen Brown, ZDNet. 

For modern brands the question is not if utilizing chatbots and AI is a good idea but which chatbot software to choose. 

If you want to skip to the reviews, here’s our list of the best chatbot platforms:

If you’re not in a hurry, let’s dive deeper and look at what chatbots really do.

What is a Chatbot?

According to this Oxford Dictionary, a chatbot is:

A computer program that can hold a conversation with a person, usually over the Internet

To expand on this definition, the word chatbot derives from “chat robot” and is a computer program that can communicate, either via voice or text communication, or engage with a human, answering questions, finding products or information, and even offering advice. 

Chatbots typically communicate via smart speakers, smart devices and popular chat and messaging platforms like SMS, Facebook Messenger, WhatsApp, and LINE.

Chatbots range from basic button-oriented software applications which offer predefined answers to familiar questions to AI-powered virtual assistants that can recognise detailed questions and respond intelligently. 

The best AI chatbots rely on Machine Learning to understand the behavior of the individual user and better answer her enquiry. 

Let’s look at Mitsuku, for example:

Why Your Business Needs Chatbots

Chatbot platforms are improving all the time and the most compelling reason to use them is cost savings. 

Back in 2017, IBM found that chatbots could help businesses quickly save up to 30% on their customer support costs. 

Juniper Research suggests this figure will continue to grow and, by 2025, companies will be saving $11 billion in support costs by using chatbots.  

The future for chatbots does look bright. Consumers already engage with many of them on a daily basis and, in fact, this is great news for businesses because complaints are resolved 90% faster with a chatbot. 

Faster responses can lead directly to more sales because many consumers are making buying decisions based on customer service above other variables. Not only that but, as per PwC, they are willing to pay up 16% more for products and services from brands which deliver excellent customer experiences.

What Can You Use Chatbots For?

Chatbots are often used to answer simple customer service questions and requests for information. But, in addition to this, they can also capture and convert leads, automate work efficiency and give product recommendations. 

Here are a few use cases for chatbots. 

Lead capture

You can use a chatbot on a landing page or on a Facebook page to engage the visitor in a conversation. Many SaaS companies like Broadly (below) are doing this to understand visitor intent.

24/7 customer support

Instead of having to hire multiple customer service agents to manage your various digital channels 24/7, you can make use of chatbots on social media as well as your website. In fact, a study by Edwards, C., Beattie, A., Edwards, A., and Spence, P. found that twitterbots and human agents were rated similarly by participants for their ability to learn from and gain information. 

Essentially, bots were viewed as credible and competent for communication tasks, making them a great solution to handle your support when agents are unavailable. 

Ease agent workloads

In addition to 24/7 support, by using chatbots to handle your support frontline, you can enable customers to solve simple problems on their own. 

For example, your bot can be connected to your knowledge base or wiki and programmed to answer FAQs.

In turn, with your chatbot answering simple, repeat questions, you can ease your support team's workload, enabling them to more effectively deal with complex issues. 

Recruiting and employee onboarding 

HR chatbots can help with recruiting by conducting surveys among candidates. 

They can also be used to answer employee questions such as “How many leave days do I have?”

Product and service recommendations 

Bots can be programmed to recommend products and take user orders. For example, the AirBnB chatbot can find a place for you to stay and make the booking for you.

Work automation

Chatbots can be a great tool to streamline frequently-performed tasks. A testament to this are the numerous Slack bots which automate repetitive tasks, helping workers save time and be more productive.

Gathering customer data

Not only does a bot improve the user experience, but it can also analyze user behavior and make the insights available to your sales and marketing teams. 

Most chatbot platforms provide analytics that help you gauge customer satisfaction. 

Some can also be connected to your CRM to enable you to understand the buying journey more easily.

Types of Chatbots

Based on the level of complexity and the quality of the user experience, chatbots can be categorized in three main groups: Button-based, Keyword-based and AI chatbots. 

Types of chatbots: button-based, keyword-based, and AI

  • Button-based chatbots
    These chatbots can only answer a set of predefined questions. The user is presented with a menu that contains the different options.
  • Keyword (NLP) chatbots
    Moving up the complexity ladder, these chatbots utilize customizable keywords and AI to find the best response to the user’s query. They try to conduct a free-form conversation and can usually interpret language correctly.
  • Contextual (AI) chatbots
    Contextual chatbots are the most advanced kind of conversational bots. They utilize machine learning and AI to remember conversations that happened in the past, with specific users, to learn and grow over time. Siri, Alexa, Google Assistant are some examples of contextual chatbots.

How to Choose a Chatbot Solution

Here is a list of the questions to ask when setting your mind on a chatbot solution: 

  • Who will build it? If you can dedicate internal development resources, you can go with a chatbot platform that requires programming knowledge. If not, look for one that allows you to design the bot’s flow with code-free tools such as a drag-and-drop editor.
  • Where will you publish it? Consider the bot’s integration channels: Will you be using the chatbot on your website, on social media, in mobile app? Does the platform support the outlets you need?
  • Will you get user insights? Whether you need the bot for marketing or customer support, analytics are a must-have, so check for this functionality. 
  • Will it integrate with your existing software? For example, if you plan to use the bot for lead capture and you’re going to send the leads to your CRM, you have to make sure that the chatbot platform can be integrated with your CRM. 
  • Can it hand-off conversations to a live agent? If you need the bot for customer service, this feature is essential.
