So let’s get started

What is a Chatbot App?

Chatbot app is a web or mobile application that utilizes artificial intelligence and natural language processing to simulate human-like conversation and answer queries. It is an automated computer program that interacts with users as humans would. Chatbots provide solutions to given problems, answer questions, and operate in different ways to interact with and help users.

Types of Chatbot Apps

There are various kinds of chatbots depending on their purpose and functionalities. A chatbot might work on a website as virtual customer assistance. Or it can be voice assistants like Siri, Alexa, or Google Assistant installed on smartphones or mobile devices.

However, most chatbots use NLP, AI, and ML models to perform actions based on the given user’s commands. So based on their use case and functionalities, below are the most popular types of chatbot apps.

  1. Button-based chatbots
  2. Rule-Based Chatbots
  3. Keyword recognition-based chatbots
  4. Contextual Chatbots
  5. AI Chatbots
  6. Voice chatbots
  7. Hybrid chatbots

What is ChatGPT?

Chat Generative Pre-Trained Transformed or ChatGPT is an AI chatbot application that interacts with users in a human-like conversation way. It is an autoregressive language model which utilizes deep learning and artificial intelligence to solve queries and generate other content. ChatGPT is owned by OpenAI which was launched in Nov 2022.

This is a fully AI-powered chatbot application equipped with the advanced capability to recognize and respond to users’ inputs accurately. It generates a variety of content like coding solutions, sales pitches, news summaries, general queries, and academic and other forms of content quickly.

Why Is ChatGPT Different From Other Chatbots?

Chatbots aren’t a new concept about which people are talking a lot these days. It has been running for many years in the industry. Businesses and companies have been using chatbots on their websites and software. However, these chatbots have limited capabilities. They could perform only certain actions like responding to predefined queries, assisting in customer service, and writing simple content.

But ChatGPT defeated all the traditional chatbots through its advanced and extended capabilities. It is the first kind of AI chatbot in human history that has impressively demonstrated the effective use of artificial intelligence, NLP, machine learning, and deep learning. This chatbot offers a fast and convenient human-like chatbot facility for a diverse range of queries and user requests.

It has more intelligent features which help users from every domain to get quick and near-accurate answers or solutions to their inputs. Here are the key features that stand out ChatGPT from conventional chatbots in the market:

  • Wide range of language inputs
  • Great ability to learn and understand
  • Cost-efficient
  • Offer enhanced chatbot user experience
  • Help in app development
  • Design for all industry domains
  • Aid in business intelligence and decision making
  • Useful in narrow and simple online search
  • Enhance work efficiency through automation

How Does ChatGPT Work?

So you have got the basic and essential understanding of what features make ChatGPT unique and revolutionary. Now, let us understand how ChatGPT works. This will give you an idea of how your chatbot mobile app will work and function.

ChatGPT is built on the GPT-3 model. It primarily involves semi-supervised learning algorithms by ML developers and data scientists. This is actually the OpenAI GPT-3 model which is designed as a neural network to simulate data processing like a human brain.

How Does ChatGPT Work?

It is the largest NLP model ever built in the chatbot development industry that contains 175 billion parameters. Let’s break the GPT term so it will give an overview of its body.

  • G (Generative)- It means an initiator or generator
  • P (Pre-Trained)- It leads automatically, which means it doesn’t need any training or learning
  • T (Transformer)- This is an ML model that recognizes or identifies content

ChatGPT works on the transformer architecture. It facilitates the processing of a large volume of data and learning to operate the tasks of natural language processing (NLP) efficiently. This AI Chatbot app is pre-trained for handling a large size of dataset of text and answering questions from diverse subjects.

It can fetch data from user interaction. And then adapt the answers in a conversant way. Its unique ability to generate human-like responses makes it appealing and gives a nice user experience.
