‍

In this comprehensive guide, I'll share 11 of the best conversational AI platforms on the market today. Custom conversational AI is fruitful starting ground for scaling your operations, enhancing customer support, and saving your employees from routine tasks.

The best conversational AI will always be the one that works exactly how you want it – we’ll help you find the platform that best suits your needs. 

What is conversational AI?

Conversational AI is a collection of technologies that enable machines to understand and respond to human language.

Using natural language processing (NLP) and machine learning, conversational AI is used to power AI agents, AI chatbots and AI assistants.

Conversational AI entities are commonly employed as voice assistants, customer support chatbots, information retrieval agents, or chatbots like ChatGPT.

Benefits of Conversational AI

Implementing conversational AI is beneficial for employees, customers, and users alike. They can collect and provide data for customers, easily allow for human intervention, and save time for workers. 

24/7 availability

Unlike a human, a chatbot can work around the clock. While 24/7 service is exceptionally costly with live agents, it’s a built-in feature of a chatbot. 

If you have an international user base, or provide key services (like IT support), 24/7 service is a necessity for your success. A conversational AI chatbot is a natural extension of your business offerings. 

Scalability 

If your organization is looking to scale, conversational AI is necessary for your communication channels. It's cheaper, always available, multilingual, and integrated with all your systems.

A chatbot provides improved customer experience and enables revenue growth for your company.  

Fast and consistent service

Conversational AI solutions are available 24/7 – and they can handle many customer queries simultaneously. 

And the best part? AI chatbots never have a bad day. Their service is exactly what you want, whenever your customer wants it. 

When powered by LLMs, their natural language understanding means that even complex customer questions – beyond the level of a simple FAQ – can be handled in large numbers.

Multilingual support

Every chatbot can interact in multiple languages. 

An AI chatbot can interact with your users in their native language, at no additional cost. While a human team that speaks 100 languages is prohibitively expensive, it’s a built-in feature of LLM-powered conversational AI.

Integration capabilities

The best conversational AI platforms will allow you to connect your bot to other systems – your AI agent can take data from any Knowledge Base and use it to source outgoing information. 

Knowledge databases like Google sheets, your website, any documents, your Calendly availability – all of these and more can be synced up with your bot. 

An AI agent builder like Botpress provides pre-built integrations to platforms like Slack, Microsoft Teams, WhatsApp, Google Analytics, Intercom, Facebook Messenger, Mixpanel, Linear, Notion, Zapier, Trello, Asana, Zendesk, and many more. 

The best platforms will be endlessly extensible – you’re able to build in integrations to any platform or software in existence. When you pick a conversational AI platform for pros, you can build it to accomplish anything you want.

FAQs

1. What are the main differences between conversational AI, chatbots, and virtual assistants?

The main difference between conversational AI, chatbots, and virtual assistants lies in complexity and capabilities: chatbots are typically rule-based and handle scripted flows (like FAQs), virtual assistants (like Siri or Alexa) offer broader utility through voice and integrations, and conversational AI is the underlying technology that powers both, enabling natural language understanding and context-aware responses.

2. How can I calculate the ROI of using a conversational AI platform?

To calculate the ROI of using a conversational AI platform, subtract the total cost of ownership (platform fees, development, training, and maintenance) from the value gained (e.g., reduced support ticket volume, increased lead conversion, 24/7 service coverage), and divide that by the total cost. Track metrics like cost per interaction, agent deflection rate, and conversion uplift to make the ROI tangible.

3. What skills do I need to deploy a conversational AI platform effectively?

To deploy a conversational AI platform effectively, you’ll need basic conversation design skills, an understanding of customer workflows, and some familiarity with APIs or integrations. While coding is optional thanks to no-code tools, technical teams can go further by customizing flows and third-party connections.

4. How do I compare platforms if my business is focused on B2B versus B2C?

If your business is B2B, prioritize platforms that support lead qualification, CRM sync, complex workflows, and longer sales cycles. For B2C, choose platforms optimized for high volumes, multilingual chat, omnichannel support, and personalized recommendations

5. How do I ensure my AI agent sounds natural and aligned with my brand voice?

To ensure your AI agent sounds natural and on-brand, define your tone of voice (e.g., friendly, formal, witty) and write sample dialogues in that tone. Periodically review transcripts to fine-tune style and ensure consistency.
