Top 10 conversational AI platforms

Conversational AI platforms create meaningful chatbot experiences for your customers.

Through natural learning processing and machine learning, they can mimic realistic human speech patterns. Implementing these conversational AI bots helps customers resolve their queries and build long-lasting relationships with your brand.

The global market for chatbots is set to soar to $1.25 billion in 2025. So, it’s clear that AI conversation bots will continue to make waves in e-commerce and beyond. If you’d like to upgrade your current chatbot with conversational AI, it’s important to consider the features you need first. 

Weighing up the pros and cons of conversational AI software is also a must. In this post, we’ll set out the top 10 conversational AI platforms available, including their key features and benefits.

Conversational AI use cases and examples

Using an AI chatbot for businesses

How can your business utilize conversational AI tools? There are many different use cases where they can make a difference. Here are a few key examples.

Conversational AI for customer service 

A conversational AI bot can send personalized, automated messages to customer queries.  

It can “understand” your customer’s query, taking into account the message’s context and tone. It can then link up with human customer service agents, where needed.

A customer support helping his client

Example: how a beauty brand can personalize customer messages with conversational AI

Let’s say your customer has a query about the cost of your shea butter face scrub. Your AI conversation bot can provide a tailored, on-brand response, understanding your customer’s intent. 

If the customer then brings up a more complex query about a missing order, the AI will know when to transfer to a human agent. In this case, they’ll typically send it to the customer service or order fulfillment teams, as the AI intuitively knows the agents best suited to answer each customer query.

Marketing with conversational AI

AI marketing

Conversational AI software also has many marketing features, from sending notification messages to helping you qualify leads. Conversational AI bots also ensure that any data received from customers can be utilized to personalize their marketing messages. 

From the database you uploaded, the AI chatbot can be trained to remember details from the customer, so if they later make a sales query asking for product recommendations, your AI can take their budget into account.

Conversational AI sales

AI conversation bots help your business provide a quick and efficient service, boosting your repeat sales. Plus, responses and recommendations are instantly personalized to your customers and brand without any laborious effort on your part.

Sales agent drafting Shopify orders in the chat

Example: how an e-commerce sportswear brand can boost sales with better CX via conversational AI

A customer wants to purchase a new pair of running shoes, but due to their working hours, they can only order at night. That’s outside your traditional operating hours. Fortunately, you have a conversational AI bot to hand. The chatbot helps your customer find the right product and make the sale in record time. 

It also recommends a waterproof high-vis jacket to the customer, which they order too. The customer leaves feeling satisfied with their purchase. You can also have follow-up automated messages in place to help them keep track of their delivery.
