What about Zed or something else?

I have not used any IDEs like Cursor or Zed, so I am not sure what I should be using (on Linux). I typically just get on Claude (claude.ai) or ChatGPT and do everything manually. It has worked fine for me so far, but if there is a way to reduce friction, I am willing to give it a try. I do not really need anything advanced, however. I just want to feed it the whole codebase (at times), some documentation, and then provide prompts. I mostly care about support for Claude and perhaps Gemini (would like to try it out).
