In this blog, We will be discussing the Top 7 Chatbot Development Frameworks.

Chatbots have now become integral to many businesses. They leverage chatbots for the customer support service. The chatbot augments the human agents to deliver customer service support. Businesses get tons of queries every day. Answering them manually not only is time-consuming but also adds to the company’s costs since they have to hire more people for customer support service. Today, the lack of a prompt response usually causes customers to become frustrated. This could ultimately lead a business to lose a customer. That is why having efficient customer service is at the core of every business process.

This is where the use of chatbots comes into the picture. Just imagine how efficient and convenient it will be if there is a bot that answers all the queries of the users. This imagination has been turned into reality using AI.

A chatbot is a computer program that simulates and processes human conversation (either written or spoken), allowing humans to interact with digital devices as if they were communicating with a real person.

You must have found chatbots on many websites you visit like an ed-tech website. Did I guess that right? Super! Yes, the chatbot can handle all the queries like inquiries about a course/Bootcamp. The chatbots are made so intelligent that you can even book movie tickets or flight tickets just by instructing the bot. Chatbots leverage the power of NLP (Natural Language Processing) to make it super intelligent.

According to a report by Outlook (2018), 80% of businesses are projected to integrate some form of chatbot system by 2022.

So, this is the right time for you to learn to build chatbots like Alexa or Google Assistant. There are various frameworks available that enable you to build and integrate chatbots seamlessly.

So, without wasting any further time, let us start discussing the Top 7 Chatbot Development Frameworks.
