Whether on Facebook Messenger, their website, or even text messaging, more and more brands are leveraging chatbots to service their customers, market their brands, and even sell their products.

But, the if/then logic that powers many chatbots’ conversational abilities limits them from answering unique and new questions, which can hang your customer out to dry and leave them dissatisfied with your customer service — luckily, AI-powered chatbots that can solve that problem are gaining steam.

In this post, we’ll discuss what AI chatbots are and how they work and outline 18 of the best AI chatbots to know about.

The most important thing to know about an AI chatbot is that it combines ML and NLU to understand what people need and bring the best solutions. Some AI chatbots are better for personal use, like conducting research, and others are best for business use, like featuring a chatbot on your website.

Conversational AI vs Chatbots

Conversational AI and chatbots are related, but they are not exactly the same.

Conversational AI is a broader term that encompasses chatbots, virtual assistants, and other AI-generated applications. It refers to an advanced technology that allows computer programs to understand, interpret, and respond to natural language inputs.

Although AI chatbots are an application of conversational AI, not all chatbots are programmed with conversational AI. For instance, rule-based chatbots use simple rules and decision trees to understand and respond to user inputs. Unlike AI chatbots, rule-based chatbots are more limited in their capabilities because they rely on keywords and specific phrases to trigger canned responses.

Use Cases for AI Chatbots

AI chatbots are used in a wide range of applications across many industries, helping businesses streamline operations and increase productivity, provide better user experiences, and improve customer service. Here are some ways you can use AI chatbots to enhance processes within your organization:

Customer Support

  • Provide 24/7 support to your customers
  • Address FAQs
  • Solve simple issues through a chat interface

Sales and Marketing

  • Answer initial inquiries about products and services
  • Provide recommendations
  • Help customers with purchase decisions

Writing and Editing

  • Generate content ideas
  • Create article outlines
  • Draft emails, social copy, and paragraphs

Recruitment and HR

  • Engage with potential job candidates
  • Answer basic questions about open positions
  • Schedule interviews and meetings

Benefits of AI Chatbots

Having an AI chatbot on your company website can bring numerous benefits, no matter what industry you’re in. Here are a few key advantages:

Improved Customer Experience

AI Chatbots provide instant responses, personalized recommendations, and quick access to information. Additionally, they are available round the clock, enabling your website to provide support and engage with customers at any time, regardless of staff availability.


As your business grows, handling customer queries and requests can become more challenging. AI chatbots can handle multiple conversations simultaneously, reducing the need for manual intervention. This ensures faster response times and improves overall efficiency. Plus, they can handle a large volume of requests and scale effortlessly, accommodating your company’s growth without compromising on customer support quality.

Data Gathering and Analysis

AI Chatbots can collect valuable customer data, such as preferences, pain points, and frequently asked questions. This data can be used to improve marketing strategies, enhance products or services, and make informed business decisions.

Lead Generation and Support

AI Chatbots can qualify leads, provide personalized experiences, and assist customers through every stage of their buyer journey. This helps drive more meaningful interactions and boosts conversion rates.

With this in mind, we’ve compiled a list of the best AI chatbots for 2023. Read on to find the right one for you.
