Key Takeaways

• This article compares 7 chatbot software options across 3 use case categories: omnichannel customer service (SaleSmartly, Subiz), social media selling (Fchat, ManyChat), and general-purpose AI chatbot platforms (Tidio, Bizfly Chat, FPT.AI).
• The right chatbot software depends on your team's primary communication channels, required level of automation, integration capabilities with existing systems, and language support.
• Each chatbot software suits a specific customer segment and team size. Your team should identify its needs clearly before evaluating features.

The chatbot software market currently offers dozens of options, ranging from simple script-based chatbots to AI-powered platforms with natural language understanding. For customer service and marketing teams, the question is no longer whether to use a chatbot but which chatbot fits your communication channels, team size, and operational goals. This article compares 7 popular chatbot software options, organized by 3 use case categories so you can evaluate and choose efficiently.

Which Chatbot Should You Use? Criteria For Choosing The Right Chatbot Software

The answer depends on four factors your team needs to evaluate before comparing features across platforms. These four criteria help you narrow down the list and avoid choosing the wrong tool from the start:

• Primary communication channels: Which channels does your team use most to interact with customers (Zalo, Facebook Messenger, Instagram, WhatsApp, website live chat, or email)? The chatbot software needs to support those channels.
• Level of automation: Do you need a chatbot that answers simple FAQs, or an AI chatbot that can consult on products, classify requests, and hand off to agents?
• Integration capability: Which existing systems does the chatbot need to connect with (CRM, order management, inventory, call center)?
• Language support: Does your team serve only domestic customers, or do you need multilingual support for international customers?

The table below provides a quick comparison of all 7 chatbot software options reviewed in this article:
