Chatbots 101: Understand the Basics Before you Make your Pick

Before you pick the best framework for your business, let’s make sure you understand the basics of chatbot development:

A chatbot is an automated customer interaction system that analyzes user input and provides a detailed response to that input based on the information available in the chatbot database.

Chatbots provide a variety of benefits for your business:

  1. 24/7 customer support availability
  2. Immediate response time
  3. High response rates (35-40%)
  4. Reduced customer support costs
  5. Huge time-saver
  6. Automated storage of customer data
  7. Integrated with the CRM of your choice

There are two general types of chatbots:

  • Simple, a.k.a. knowledge-based chatbots: These chatbots analyze customer queries based on the keywords entered, and then provide automated responses to such questions based on the information previously uploaded in the chatbot database.
  • AI-powered chatbots: These chatbots use machine learning (ML) and natural language processing (NLP) technologies to generate the best responses for customer queries automatically. Such chatbots learn as they interact with more customers, and require some advanced training in the early stages.

Now that you understand all the basic chatbot terminology, let’s get to know our contestants.

Now, let’s look at the best chatbot development frameworks and see what makes them unique.
