Cursor is still your best bet. While it says "coding" on the label, it also connects to all the top models and can be used to ask about anything, not just code.

Cursor is still your best bet. While it says "coding" on the label, it also connects to all the top models and can be used to ask about anything, not just code. The main advantage of Cursor is that it can read and write files on your disk, especially Markdown. That way, you have immediately saved your prompts and responses locally and you can feed them back in for action or refinement. The fact that it's an editor makes all the difference.
