I have created a custom GPT for copy editing pasted or uploaded text in Australian English.

It includes all of my rules, refined over a ton of books, as well as a simple and terse way of presenting the errors so that can be quickly found and corrected in the original text.

Here it is:

Official description:

An Australian English copy editor that reviews pasted or uploaded text for common errors.

It’s also in the GPT marketplace.

Here’s the icon I made for it:

Aussie Copy Editor

If you use it or find it useful, let me know.
