We also explain recommended tools based on your company size and goals, as well as key points on how to choose without making mistakes. This article covers all the information you should check before implementation, serving as a reference for selecting the best tool.

What Is an AI Customer Support Tool? Capabilities and Key Considerations Before Choosing

AI customer support tools learn from a company's help center articles and past inquiry history to automatically answer customer questions. They go beyond simple chatbots, with some capable of executing specific actions by integrating with backend systems, such as checking order status or processing returns.

• Automatic responses through natural conversations based on learning from FAQs and help articles
• Efficient ticket routing via automatic classification and prioritization
• Automation of tasks such as referencing order information and processing returns
• Drafting responses and summarizing content to assist human agents
• Providing consistent support to global customers through multilingual support

Before implementation, you should check the scope of free usage and whether Japanese support is available. For example, Freshdesk Freddy AI and Chatbase can be tried from a free plan, while tools like Tidio AI and Help Scout AI do not support Japanese. Additionally, costs and implementation difficulty vary significantly depending on whether the tool assumes use of an existing platform, such as Intercom Fin or Zendesk AI, or requires custom quotes for enterprise use, like Ada or Yellow.ai.

Furthermore, supported platforms are important. Many tools support integration via API, in addition to embedding on websites and iOS or Android apps. However, if you plan to use the tool in an on-premises environment, you need to choose products with a wide range of compatibility, such as Yellow.ai. It is essential to carefully evaluate the balance between features and pricing based on your company's size and existing system configuration.

On the other hand, Decagon and Ada autonomously resolve inquiries and execute actions such as refund processing. The right tool depends on whether you want full automation or efficiency improvements with human assistance.

If ease of use is a priority, Chatbase or Tidio AI are candidates. These can be built easily without code.
