From Idea to Launch: Developing My First Chrome Extension in Just 3 Days

Inspiration

Recently, I came across several products that convert Markdown to sharing cards, and I found them quite useful. Last Wednesday, I had a sudden idea: if Markdown can be converted to sharing cards, why can't webpages?

Development Process

I decided to act on it immediately. Initially, I used Cursor for development, but the free quota ran out quickly. Then I switched to GitHub Copilot, which I had subscribed to for a year or two but had only been using as a code completion tool (now I realize what a waste that was). With the help of its Agent, I quickly completed the development of this new product.
