18 best AI chatbot software in 2024 | Key features, pros, and cons

Imagine having the power to automate engaging customer conversations, provide round-the-clock assistance, qualify leads by asking relevant questions, and automate tasks of varying complexities without skipping a beat.

While this was the dream a few years ago, AI chatbot software makes this a reality today. From enhancing the website experience to addressing every customer query, AI chatbots can do it all.

With the market quickly flooding with a variety of chatbots, we take an in-depth look at some of the best AI chatbot software available today, offering insights into how they can transform your business and support operations.

18 leading AI chatbot software for modern businesses


DevRev is an AI-native chatbot and support platform that can help deflect customer queries by engaging them in a conversation, providing relevant answers, and leading them to the right articles for more information.

By integrating AI agents alongside human intelligence, DevRev can help you automate labor-intensive tasks, offer self-service support without compromising customer experience, and enable your support and product teams to resolve complex customer issues more efficiently.

The best part about DevRev’s chatbot platform is that it can be deployed within minutes and is unrestricted by the limitations of chatbot builders and decision trees. This is a departure from the conventional way of building bots, towards a more dynamic, self-learning, and truly AI landscape.

Here’s a quick overview:

Key features:

  • Natural language processing: DevRev’s chatbot, powered by Turing AI, comprehends customer queries with advanced natural language understanding. This enables the bot to provide human-like responses, moving beyond rigid scripted replies.
  • Personalized interactions: It learns from every interaction, tailoring responses and recommendations to create a unique experience for each customer, fostering stronger customer satisfaction and brand loyalty.
  • Continuous self-learning: With DevRev’s AI chatbot, you can automate resolutions for L1 and L2 queries. As the AI chatbot performs an operation repeatedly, it learns and constantly improves the accuracy and relevance of its response with every answer that it generates, ensuring your customer service remains up-to-date.
  • Routing: When a customer raises a query that is beyond the scope of what’s available in the knowledge repositories, the AI chatbot promptly and seamlessly escalates the conversation to a human agent. It first attempts to understand the query a little more and create a support ticket for it. Next, it quickly identifies and assigns the ticket to the human agent best suited to resolve the issue.
  • Say goodbye to chatbot builders: DevRev’s chatbot can be deployed in minutes and is unrestricted by the limitations of the number of steps in flow builders. Deploying it is as easy as point, click, and deploy. There is zero decision tree management involved in the process.

The company: MAD Rewards is a global platform focused on helping businesses create loyalty programs that enhance customer engagement. They’re present in over 67 countries and have partnerships with over 10,000 to 12,000 merchants.

The challenge: MAD Rewards had a large in-house customer support team operating across 70 countries and supporting almost nine languages.

Before DevRev, when a customer required support, they’d have to email in a ticket. The team would then get the tickets from their previous support platform, assign them, and proceed to resolve the query.

The solution: In addition to email support, MAD Rewards wanted to support their customers on chat and cut down the time-consuming back-and-forth that comes with email.

With DevRev’s AI chatbot, they automated replies for basic questions that have straightforward answers where:

  • The customer explains the problem
  • The bot asks a follow-up question
  • The customer explains the next level

Based on the customer reply, the chatbot provides clear, contextual replies and relevant links for further clarification.

The result: In addition to deflecting a large number of incoming queries, they scaled down their huge support team to handle only complex queries and optimized support operations, all while maintaining customer satisfaction.

If there’s an opportunity to cut costs using modern technologies, artificial intelligence, and pattern learning, so that when a customer comes, you know exactly what they’re looking for, you better jump on it. So I was confident that DevRev ticked all the boxes and we decided to switch,”
