Pretty average dev here. It's not my profession but I do use it to make some of my living, whatever sense that makes.

Cursor is magic. Two massive use-cases for me:

1. Autocompletion of a copied function.

So I have some function, modX(paramX), and I need to duplicate it to modY(paramY). They're near enough the same. I love that I can copy/paste it, rename a variable or two, and Cursor then intuits what I need. Tab tab tabbity-tab later, job done. This might not be the most amazing use of AI but is sure as shit helps my RSI.

(I know I should abstract my functions yada yada.)

2. Generation of a new function where I have no idea how to start.

I tell the prompt what I need. "I'll give you a bunch of Markdown files and I'd like you to take the frontmatter properties and put them on an object then take each of the headers and its following content and put that in to this property on the object".

It'll do that, to 90%. I'll fix the 10%, making sure that I understand what it's created for me.

This would have taken me 4 hours. With Cursor it takes 15 minutes.
