Warp is older than ghostly and warp provides much more functions. Not only AI stuff but better editing of the shell (yea, I’m sure there is a way to get it in ghostty too), a built in run book where you can save commands (yes, you can say it should not live in the terminal)

Do you need all of them? Maybe not. Maybe. I used warp in the past (before AI) but now just Ghostty. But it required more customization to achieve just some of the stuff warp does.
