As a company, you want to be available to customers at all times. During business hours, but also at night and on weekends. 24 hours a day, 7 days a week. For many companies, it is impossible to achieve this kind of availability with only human help. An AI chatbot is then the solution.

Digital assistant gains popularity

Artificial intelligence (AI) has boomed since the entrance of ChatGPT in late 2022. And with this digital revolution, AI chatbots also became increasingly popular ánd better. Indeed, in a short period of time, an AI chatbot has become much smarter and more accessible. Where before you were stuck with slow or frustrating bots, you now talk to systems that really understand what you mean. Or at least come a long way. But what is the best AI chatbot? And what makes this chatbot so good? We list a few.

What is an AI chatbot?

Before we compare different chatbots side by side, it is good to understand what an AI chatbot is and what it can do. An AI chatbot is a smart digital assistant that uses artificial intelligence to conduct conversations with users. Thanks to natural language processing, the chatbot understands what you say or type, and responds in a way that feels natural and human.

Through a user-friendly interface, you can easily ask questions or give commands. Modern AI chatbots are able to understand and explain complex topics, or even perform tasks. Because they learn from previous conversations, they can offer personalized interactions that match your preferences, behavior or needs. Convenient, fast and increasingly smart to use.

1. upendo

Upendo’s AI chatbot is a smart digital assistant that answers questions, provides support and helps visitors find information or products 24/7. Thanks to Google’s Vertex AI, with models such as Gemini Pro and Flash, the chatbot conducts natural conversations and understands the intent behind search queries through powerful Natural Language Processing. The integrated search function instantly delivers relevant information from various data sources. It is constantly learning, getting smarter and perfectly aligned with your data and processes. The user-friendly interface, simple integrations and high performance make this chatbot ideal for personalized interactions and relieving your team.

2. UChat

With UChat, you easily compose conversations through a clear drag-and-drop editor. The chatbot works on a variety of channels simultaneously, including WhatsApp, Messenger, Instagram and even voice channels. With AI integrations such as ChatGPT or Dialogflow, the bot can provide natural and personalized responses. UChat is thus not only useful for customer service, but also for automation of recurring tasks. In addition, you can watch live or jump in via a central inbox. This way you combine automated contact with personal support, without making it very complicated.

3. Amazon Lex

Amazon Lex is a chatbot platform from Amazon that lets you create smart bots that understand both text and speech. Lex runs on the same technology as Alexa, so you get powerful speech recognition and language understanding right away. You can link Lex to other Amazon services such as Lambda or DynamoDB, allowing your bot to actually execute commands. Useful for customer service, internal tools or voice assistants. The visual editor makes building conversations a bit easier, but you need to be a little bit savvy in AWS. For small applications, it’s affordable, but with high traffic, the cost can add up quickly.

Through a user-friendly interface, you can develop bots that understand natural language and communicate through more than 30 channels, such as websites, apps and voice platforms.

How does a smart virtual assistant learn?

A self-learning AI chatbot learns from everything it reads as well as from the conversations it has. It is trained to give accurate answers with, for example, frequently asked questions, different sources, web texts and manuals. Is new information added or does someone give feedback? Then the chatbot adapts accordingly. This way it gets smarter and smarter.

Does someone ask “How do I set up an AI chatbot?” and the answer is unclear? Then you can edit that. The next time, the correct step-by-step will pop up immediately. This keeps your chatbot up to date, but also a really powerful tool!
