Bought GitHub copilot. Best work expense, ever. Highly suggested.
Answers for some common questions in the comments :
Chatgpt free version has been good enough for me, but what copilot has, is context. It has my entire codebase so I can prompt like - do x here like y in file abc.js
What it's best for is repetitive stuff. I don't want my AI buddy to do everything for me, I want it to be an assistant, do the boring stuff, which it does very well.
Edit : Will switch it out with the cursor AI next month
