A plugin is a software extension that brings additional functionality to an existing application, especially when implementing the additional functionality in the base code is complex and time-consuming.

Plugins are one of the best ways to use a service beyond its limitations. As of now, there are more than 230 plugins available for ChatGPT. Now, the question is how to create your own ChatGPT plugin. Therefore, we have provided here a step-by-step guide on how to create a ChatGPT plugin.

Ordinary plugins vs. ChatGPT plugins

The main difference between ordinary plugins and chatGPT plugins is that ChatGPT's plugins are specifically made to meet the needs of AI-based solutions, midjourney api while other plugins are not specifically built for AI chatbots and may contain unnecessary or essentially redundant steps.

ChatGPT plugins are mainly used to create custom plugins to solve specific problems or tasks that an organization has at the time. ChatGPT plugins also feature seamless use, while other plugins may have free package restrictions, which ChatGPT plugins may not have.

The most popular types of plugins in ChatGPT are mainly translation plugins (for translating into different languages), task-oriented plugins (plugins created for specific tasks), entertainment plugins (including games, quizzes, jokes, etc.), and social media plugins (enabling ChatGPT to interact with social media platforms).

Some of the most popular plugins used recently in ChatGPT include:

OpenTable (restaurant reservations)

Speak (communicate in different languages)

Zapier (provides seamless communication via prompts in Gmail, MS Teams, Outlook, etc.)

Wolfram (provides real-time data access)

With the release of GPT-4, they released a beta version where one can use the existing plugins in GPT or go further and create our custom plugins. Here, we will learn how to create and implement custom plugins in ChatGPT.

Creating ChatGPT Plugins – Step-by-Step Guide
Basic Overview

Before we start creating plugins, we need to decide on the basis of the plugin. Here, as a demonstration, the headlines of the news will be displayed using the News API, which is a free API, you can sign up and get a free API key that will help you use the API for your own projects. After creating the application that uses the API key, we wrap it in an application and host it in the server so that ChatGPT can browse the server and print the headlines through ChatGPT.

Installation

For this, we need to install the Waitress library in our repl.it library which is commonly used in developer applications to make requests using the following command:

pip install waitress

Besides this, we need to import the requests library in order to send requests to the API URL. We also need to import OpenAI in order to create a ChatGPT plugin in our system without using ChatGPT Plus.

pip install --upgrade openai

First, visit the News API at newsapi.org and sign up for an account.

After signing up, you will be given an API key that you can use to integrate your work through the API.

Note: Any API key should be kept confidential. If the key is leaked, a new API key can be generated.

Now that we have the API key, let’s run a simple program that utilizes the API to print the headlines of Indian news.

Step 1: Test and Create

To build the application, we first need to test its features individually and then combine them into an application on which we can develop plugins. In this case, we will use a News API key to help us print the headlines. This code will become the basis for our plugin development later.

Code: Python #import the requests library import requests
def fetch_news(api_key):
url = "https://newsapi.org/v2/top-headlines"
params = {
"country" : "in" , # Replace with your desired country code
"apiKey" : api_key
}
# Send a request to the API URL to get the top headlines
response = requests.get(url, params = params)
data = response.json()
# Set a limit and parse through the available articles provided by the API
if response.status_code = = 200 :
articles = data[ "articles" ]
# Print the title and its source

for
article
in
articles:

title
=
article[
"title"
]

source
=
article[
"source"
][
"name"
]

print
(f
"{source}: {title}"
)

else
:

print
(
"Failed to fetch news:"
, data[
"message"
])


# Replace 'YOUR_API_KEY' with your actual News API key
API_KEY
=
'YOUR_API_KEY'

fetch_news(API_KEY)

After importing the requests library, fetch the top news headlines using the URL of the API and specify the country and API key. Then make a request from the API and store the response as data in a JSON file. The output of this code prints the most popular news headlines and their citations or news media. The output is executed in Windows Powershell.

Output:

Step 2: Wrap the functionality into an application

We need to wrap this functionality into an application so that we can turn it into a plugin. We can refer to the other functionality provided in the linked News API.

In order to create a plugin, an HTTP server domain is required, in this case, we need to create our own domain. In this demo, Repl.it is used as a hosting domain because it provides a free HTTP domain where we can send requests, which ChatGPT does when using plugins.

After that, we need to create an OpenAPI application, which is very different from a Flask application. Detailed instructions on how to create a plugin are provided in OpenAPI.
