In case it's not obvious to OP, you can use the Raycast Pro feature to select text in Apple Notes and then select the "Improve Writing" AI action.

If you were money-constrained, you could also set up a solution using macOS Shortcuts, but it would be a bit less polished. For example:

- Get Clipboard (Because IIRC, Selected Text isn't yet an action in Shortcuts, so you'd have to CMD-C it.

- Feed that to Get Contents of URL. You'd have to build the API request yourself. Be sure to include a prompt related to "improve writing". Examples on Github).

- And so on.
