WriterAI is an AI-based content writing tool that can turn your unstructured text into engaging content and generate up to 5 different paragraphs with an input of just 5 words! Using the power of artificial intelligence, this tool helps you write an engaging piece of content and end up with something professional. You can use it for writing emails, blogs, articles, letters, thesis and even e-books! It is completely free to use and open-source :)
This project is developed by Team 404 for Hashnode x PlanetScale hackathon. This team comprises of Ishant and Vaibhav.

- Inbuilt Text Editor - For writing your blogs, emails, letters, e-books and other stuff
- Project Sharing - You can share your project with unlimited number of users and work in teams
- Markdown Support - You can add images, tables, hyperlinks and code snippets in your projects by using markdown syntax
- Project Download - You can download your projects in JSON, XML and Markdown formats
- Platform Compatibility - WriterAI is highly responsive and has been tested on the latest versions of Chrome, Safari and Opera Mini
- User Authentication - Supports Email-Password authentication and Google Mail authentication
- User Authorization - WriterAI keeps on validating the user's auth tokens every 5 minutes automatically in order to prevent any unauthorized access
-
The frontend of WriterAI is created using technologies like CSS, ReactJS and MaterialUI. WriterAI is highly responsive and is tested on all popular browsers like Chrome, Safari and Opera Mini. For handling the react state\s, ContextAPI is used. The frontend code is highly structured and BEM convention is followed throughout the entire CSS code.
-
The backend of WriterAI is built using the power of Ktor, Kotlin and PlanetScale! It follows MVC architecture, DRY and SOLID code principles. Currently, the backend part is deployed on Linode, which is a popular cloud service provider platform for deploying your backend and database!
To setup the backend of WriterAI,
- Clone this repository and open it in Intellij IDEA IDE
- Create an account on PlanetScale and get the DB URL, USERNAME and PASSWORD
- Create an account on Linode and there, setup an ubuntu server using their docs
- Install java, nginx, ufw and certbot
- Open ports for http and https using ufw
- Set up NGINX by going through linode's docs. Ensure that it listens to 8080 port
- Enable SSL using certbot (You will be needing a domain for that)
- Now in Intellij IDEA, install shadowJar plugin and export the fat jar file
- Upload that jar file to linode using scp tool in linux from your local machine
- Then open your linode's terminal on your local machine using ssh
- Then type:
vim /etc/environment
12. Then in the file opened, type:
export DB_URL = planetscale-url
export DB_USERNAME = planetscale-username
export DB_PASSWORD = planetscale-password
export PORT = 8080
- Then press Ctrl+W to save and Ctrl+QA! to exit
- Then go back to root directory by writing cd ../../ and then in terminal, write:
source /etc/environment
This will update the environment variables
-
Lastly, setup a firebase account and setup up Firebase ADMIN SDK by following this and paste the config json file in resource folder. Ensure that you need to use the same file for frontend part as well
-
Finally, start the server by going to the directory where you backend jar file is and writing:
java -jar your_backend_file.jar
- Linode - Linode is a popular cloud hosting service provider where you can deploy your backend
- Ktor - Create asynchronous client and server applications using the power of Kotlin.
- Kotlin - A modern programming language that makes developers happier.
- PlanetScale - A MySQL-compatible serverless database platform.
- Jetbrains Exposed - Jetbrains Exposed is an ORM framework for Kotlin.
- Koin - Koin is a smart Kotlin dependency injection library.
- Firebase - Uses Firebase Admin SDK for authenticating and validate user's JWT auth token.
The backend of WriterAI uses MVC (Model View Controller) architecture.

}The backend of WriterAI provides many APIs to perform different operations such as insert user, getProjects, share Project, get all shared projects etc. All the available APIs and their corresponding routes can be found inside the routes folder.
The project uses PlanetScale as its database and is made for the Hashnode X PlanetScale Hackathon.
