Building My First Chrome Extension as a Beginner: Content Analyzer Pro

Learning web development and SEO inspired me to build my first Chrome extension. I wanted a simple tool that could analyze content without relying on large online platforms, so I created Content Analyzer Pro.

The extension helps users quickly review their content by providing useful writing statistics such as word count, character count, keyword density, repeated word detection, readability insights, automatic saving, dark mode, and TXT export.

The project was built using Manifest V3, HTML, CSS, and vanilla JavaScript. During development, I ran into several challenges, especially while working with Chrome's storage API. Fixing those issues taught me a lot about debugging and how Chrome extensions work behind the scenes.

I also created an official landing page where I explain the extension and its features:

The complete source code is available on GitHub for anyone interested in exploring how the extension works or suggesting improvements:

This project is part of my learning journey. My goal is to continue improving it while learning more about SEO, Chrome extension development, and creating useful tools for others.

If you have feedback or ideas for new features, I'd be happy to hear them. Every suggestion helps me improve both the extension and my skills as a developer.
