How to Create a Text Improver App with AI21 Labs: A Step-by-Step Tutorial

What is AI21 Studio?

AI21 Studio is an advanced AI development platform designed to simplify and make the development of Natural Language Processing (NLP) applications more cost-effective for businesses. It provides a range of models and APIs that enable developers to build, train, and implement their own NLP applications efficiently.

Getting Started with AI21 Studio

To start using AI21 Studio, follow these steps:

1. Create an account on the AI21 Studio website.
2. Sign up for a free trial, which will grant you access to the Playground—a user-friendly environment to explore various models and features of the platform.
3. Experiment with the Playground to familiarize yourself with the platform before creating your own projects.

Understanding the Text Improvements API

The Text Improvements API utilizes AI21 Labs' state-of-the-art recommendation engine, optimized for delivering high-quality text improvements swiftly. This API is the foundation behind applications like Wordtune, offering suggestions that enhance the clarity and effectiveness of written content. It's recommended to test this endpoint on the AI21 Labs Documentation page.

Creating Your Project with Next.js

To create your Next.js project for the text improvement application, use the following command:

npx create-next-app@latest text-improver --use-npm --example "https://github.com/vercel/next-learn/tree/master/basics/learn-starter"

Setting Up Your API Route

After setting up the project, save your API key in a .env.local file located in the root of your project. Name the key API_KEY. Next, create a folder called api within the pages directory and add a file named improve.js to handle API calls.

This route prepares the endpoint for calls from the frontend to the backend, leveraging the fetch method to implement a POST request that sends the text for improvement. You can specify an array of desired improvements to get tailored suggestions.

Developing the Frontend

Create an input component by adding a new folder called components with a file named TextImprovementInput.jsx. Within this component, use several useState hooks to manage the default text, the text to improve, and the improvements received from the API.

The user interface will consist of an input field and a button to fetch improvements. Implement the handleButtonClick function to facilitate this interaction.

Displaying Improvements

Once improvements are fetched and stored in an array, you can display them by mapping through the textArray. To maintain organized code, create another component called Texts.jsx, where you can manage the display and interaction with text items.

To enhance user experience, include a modal that shows the suggestions when users click on words that need improvement. This modal should be implemented in a Modal.jsx component.

Conclusion

By following the steps outlined in this guide, you can successfully set up an application using AI21 Studio to improve text functionality in an organized fashion. This setup provides a robust interface for users to engage with, enhancing their writing efficiently and effectively.
