Developer comments
Hi there! 👋 I'm the creator of PromptMaster.

I developed this extension because I use Artificial Intelligence daily and was tired of having my best prompts scattered across various notes and documents. I wanted a fast tool, integrated directly into the browser, that respects privacy by saving everything locally.

If you find this extension helpful in your day-to-day work, it would mean a lot to me if you could leave a positive review. I'm also open to suggestions for future updates!
