Having tried all the coding harnesses, I find that using Pi is exactly like using Emacs. For anything you want to build you can ask your agent and it will build it. There's tons of existing code to help you configure it. At the same time half the code is buggy, UI elements will try to overlap one another, and you'll periodically get crashes.

If you're willing to put in the work to master the learning curve and push through the issues, it can be a great tool: https://i.sstatic.net/7Cu9Z.jpg

Never learned Emacs but am a Neovim user. But similar to what I said to my colleagues as well. Codex, Claude Code are VS Code, Jetbrain. Pi is Neovim.
