I never use any web interfaces, just hooked up gptel (an Emacs package) to Claude's API and a few others I regularly use, and I just have a buffer with the entire conversation. I can modify it as needed, spawn a fresh one quickly etc. There's also features to add files and individual snippets, but I usually manage it all in a single buffer. It's a powerful text editor, so efficient text editing is a given.
I bet there are better / less arcane tools, but I think powerful and fast mechanisms for managing context are key and for me, that's really just powerful text editing features.
