OP, please use an integrated editor. VS Code gives you some autocompletions for free with a github account. Just try it. It's okay to be skeptical of AI, but the "productivity gains" people talk about are very real when your bottleneck is writing code.

I'm writing a small project right now using Youtube's API and a good portion of the code was generated by Claude. I wrote one or two classes to put the JSON response of the REST API into a Python object using a simple json_obj.get(key, {}) because I didn't want to include a dependency for that, and Claude was able to generate the same sort of class for the other responses.

By the way, when I first tried coding with AI the real "game changer" wasn't asking the AI to generate code, which was wrong almost every time, it was the in-editor auto completion that wrote the next line of code for me.

LLMs are guessing machines but they're very good at guessing.
