AI Chatbot

An AI-powered conversational interface that handles customer questions, qualifies leads, and completes tasks around the clock.

Definition

An AI chatbot is a software application that uses artificial intelligence, typically powered by large language models, to simulate human conversation through text or voice interfaces. Modern AI chatbots go beyond scripted responses, understanding context, answering complex questions, and completing tasks such as booking appointments, processing orders, or providing customer support around the clock.

When NOT to use an AI chatbot

  • When all enquiries are complex and unique: If every customer conversation requires deep expertise, a chatbot will frustrate more than help
  • When your customer base prefers human contact: Some industries and demographics strongly prefer speaking to a person
  • When you have no training data: An AI chatbot is only as good as the information it is trained on. If you do not have documented FAQs, product info, or procedures, start there first

Frequently Asked Questions

Common questions about AI chatbots for business.

Can an AI chatbot handle customer complaints?

For routine complaints (order tracking, refund requests), yes. For complex or emotional complaints, the chatbot should detect the sentiment and escalate to a human immediately. Well-built chatbots include escalation rules that ensure no customer gets stuck in a loop with an AI when they need a person.

How much does an AI chatbot cost per month to run?

Custom AI chatbots typically cost £20 to £120 per month in running costs, covering API calls to the language model and hosting. SaaS platforms like Tidio or Intercom charge £50 to £300 per month on subscription. The custom-built option has higher upfront costs but lower ongoing costs, and you own the system outright.

What percentage of customer queries can a chatbot handle?

A well-trained AI chatbot typically handles 60 to 80 percent of routine customer enquiries without human involvement. This includes FAQs, order tracking, appointment booking, and basic product questions. The remaining 20 to 40 percent get escalated to your team, who can then focus on the complex, high-value conversations.

Do customers dislike talking to chatbots?

Customers dislike bad chatbots. The old-style rule-based bots that could not understand questions were frustrating. Modern AI chatbots that understand context, give accurate answers, and know when to hand off to a human are well received. The key is transparency (let customers know they are speaking to AI) and quality (make sure the bot actually helps rather than creating another obstacle).
