25 Best AI Chatbot Software In 2021

Chatbots can be helpful tools for automating customer service and capturing leads. That’s why it is important to pick the right tool to suit your needs.

With so many products available, it is tough to decide which ones are the top chatbot tools. To make your life easier we spent hours going through dozens of products and putting together a carefully curated list of top 30 chatbot software platforms - from simple bot builders to more comprehensive no-code and low-code AI chatbot products.


1. What Is A Chatbot?

Chatbot is an automated interface through which the user can obtain information from a machine. The interface is usually in written form (chat) and in many cases the chatbot presents the user information with a simple multiple choice type of option. 

Chatbots are used in multilingual customer support, lead generation and sales automation across a variety of channels (e.g. websites, Facebook Messenger, WhatsApp, SMS).


2. What Types Of Chatbots Are There?

Conversational AI is the umbrella term for various types of chatbots. Below we have highlighted some of the forms of different chatbots. 


Chatbots

The simplest form of Conversational AI is a chatbot. In many cases the chatbot presents the user information with simple Yes/No type of options. These if-else type statements are essentially decision trees where the user picks an answer. Upon the selection of that answer the user is given a follow-up question with a choice of answers again. 

Such solutions are useful because they are usually operated through a clickable interface. The user is presented with buttons and by clicking on the buttons the user confirms its choices and receives information. It is a quick way of showing info to users. The challenge, however, is that while the user is directed towards the answer, the chatbots at times do not provide a specific answer to the question that the user is looking for. 

Virtual Customer Assistants

An advancement from a chatbot is a Virtual Customer Assistant (VCA). These intelligent agents are not only capable of presenting a multiple choice selection of answers to the user but also understand user intent from free text. Understanding natural language is a significant leap. Many times users are looking to articulate their specific concern to the machine in a similar manner they would do to a human. User has a question and asks that specific question from the machine e.g. “Who built you?” and the VCA gives a specific answer.

Agent-assist Systems

The third Conversational AI category can be defined as an agent assist system. These solutions do not directly interact with users. Rather they help customer service agents in giving accurate and timely answers to users. 

As an example, such agent-assist systems listen in on what users are telling customer service agents. The system is not responding to users directly. Instead, the system is telling things to the customer service agent that she should tell the user. 

One can think of these systems as smart advisors that give advice on what to tell users. It is up to the agent whether to take the advice or not. An example of this system can be a so-called co-pilot mode in live chat products. 


Voicebots

Voicebots are like Virtual Customer Assistants only instead of typing questions to them you can ask your questions by simply speaking. Users can speak to various hardware devices (e.g. Google Home, Amazon Alexa), smartwatches (e.g. Apple Watch), smartphones (Siri, Google Assistant) and also through website chat widgets (those that have a button where users can click and then speak to).


Natural Language Generation

NLG refers to the ability of the computers to generate text on their own. In the context of a Virtual Customer Assistant it means that the computer generates the answer to the question that the user is asking. 

For example, if the user asks “Where is my payment?” then the algorithms generate an answer on their own such as “Your payment will arrive in 4 hours”. In most AI solutions, the answers are pre-written. Meaning once the intent match is made, the answer is pulled from the database and presented to the user. NLG makes things more open-ended as the algorithms themselves generate text that will be used as an answer. 

Usually NLG algorithms are trained on a vast set of text. The algorithms create answers that are served to users’ intent based questions. The drawback of using NLG in Conversational AI solutions is that the answer can be inaccurate or poorly worded. As most companies want to use their own language and message when communicating with customers, pre-written answers dominate over computer generated answers. One of the recent best known algorithms is GPT-3 developed by OpenAI.

3. Chatbot Benefits

Increase Self-service In Customer Support.

When you build yourself a chatbot then they can replace human customer service agents on Facebook Messenger as well as on messaging channels such as website chat, WhatsApp, RCS and Apple Business Chat. As a result of that, customers are finding solutions to their problems on their own through bots that understand their issues and provide helpful answers. 


Reduce Customer Support Agent Workload.

Customer service agents can continue to focus on complex interactions with higher rated customers instead of handling a higher volume of cases. This is a clear benefit of chatbots in customer service.

Higher rated customers that get answers to their complex questions from human agents quickly are more likely to return to a company, which ultimately increases revenue and leads to more profitable customer support interactions. 


Capture Leads From Your Website.

If your ecommerce website has lead forms, you can get new customers but you will get only those leads who fulfill the product/service requirements. If you choose to offer live chat with a bot on your website, you can actually capture leads before they leave the website. 

This is because in the current scenario, live chat is becoming more and more common in most of the ecommerce websites. In fact, most of the popular ecommerce websites offer a live chat option. This will ensure you capture the correct leads. Use multi-linguality to appeal to a global audience. 


4. How To Choose Chatbot Software?

Before choosing a chatbot platform make sure you know the following as this will make it easier for you to choose the vendor and get a more detailed price quote.

  • What is the metric in your business you want to improve with the chatbot? Is it sales, conversions, response time, deflection rate etc? 
  • Do you have an implementation plan in place - where will you deploy it? How much real usage will you get? Can you obtain measurable data to see if your chatbot deployment was a success?
  • How many languages does the bot need to know? What is the minimal requirement of languages for you to start?
  • Do you need a chatbot-to-human-agent handover? What live chat system should the bot connect to? Will offline form for forwarding to an email address suffice?
  • Do you want the chatbot to be able to authenticate users? Connect to your backend/CRM for personalized data?


5. Chatbot Price

Chatbot prices differ because the complexity of a chatbot differs. They can run from simple if-else statement based bots to complex natural language understanding bots capable of authenticating users and retrieving and writing data into your back-end systems.


In general there are the following pricing tiers for bots:

  • Free - get a clickable bot and connect it to Facebook Messenger. The simples chatbot.
  • Agency: Setup price $500 - $3,000 and monthly price $100 - $2,000 - have an agency build you a bot, most often clickable bot, handover to email or live chat. 
  • Intelligent Virtual Assistant: Setup price $1,000+ and monthly price $1000+ - understands natural language, can chat back with customers, connected to live chat systems, custom chat widget.
  • Integrated Intelligent Virtual Assistant: Setup price $10,000+ and monthly price $5000+ - in addition to natural language understanding can authenticate your users, retrieve info from the back end systems and write data into CRM and backend, execute actions autonomously that customers want (e.g. change subscription, make transaction).
