Build Your Own OpenAI Powered Grammar Corrector

Introduction

Artificial intelligence (AI) and machine learning are gaining immense popularity today. In this article, we will explore an application of AI using OpenAI's API to create a grammar correction tool using Python. We will walk through the process step by step, demonstrating how AI can be leveraged to fix grammatical errors in text. Let’s dive into the creation of our grammar fixer project in Python!

Project Setup

Getting Started

To begin with, you need an OpenAI API key. Sign up for an account on OpenAI's website and navigate to the API section to generate your secret key. It’s essential to keep this key private. Let’s create a new Python project using PyCharm, ensuring we set up a new virtual environment. This will keep our project dependencies isolated.

Creating the Project

Open PyCharm and create a new project. Name it "Grammar Fixer."
In the terminal, install the OpenAI package by running the command:
```
pip install openai
```
Create a file named config.py to store your OpenAI key securely:
```
OPENAI_KEY = "your_openai_key_here"
```
In your main Python file, import the necessary libraries and your key from config.py.

Implementing the Grammar Fixer

Using the OpenAI Playground, you can test prompts before implementing them in code. A simple prompt could be, “Please improve grammar in this text.” For example:

I go to the shop for buy groceries.

OpenAI will return the corrected version:

I went to the shop to buy groceries.

Now let’s integrate this into Python:

import openai
from config import OPENAI_KEY

openai.api_key = OPENAI_KEY

text = input("Enter the text you want to fix grammar in: ")
prompt = f"Improve grammar in this text:\n(text)\n"
response = openai.Completion.create(model="text-davinci-003", prompt=prompt)

## Introduction
corrected_text = response.choices[0].text.strip()
print(f"Corrected Text: (corrected_text)")

Making the Tool Interactive

To enhance the functionality, you can ask users for three types of actions:

Grammar correction
Making an email more professional
Translating text to a different language

Using a match-case statement in Python allows you to provide different responses based on user inputs.

Saving the Output

To save the corrected outputs, you can write the results to a text file:

with open("output.txt", "w") as f:
    f.write(corrected_text)

Hosting as a Flask Application

To make the grammar fixer accessible as a web service, convert your project into a Flask application. Install Flask:

pip install Flask

Set up your Flask app by creating endpoints to handle requests. Unlike the desktop application, you will collect inputs via POST requests. Using Postman is a great way to test your API.

Hosting on Linode

To host this application, create a server on Linode, upload your files, and install necessary packages. Run your Flask server on the desired port, allowing access via your external IP.

Lastly, use nohup to ensure your Flask app continues running in the background. Now your grammar fixer is accessible online!
