I use TextExpander. I wanted to do some custom stuff and discovered this recently [federico-terzi/espanso: Cross-platform Text Expander written in Rust](https://github.com/federico-terzi/espanso)

I tried espanso a bit and it seemed to work pretty well and is customizable.

Keyboard (System Preferences -> Keyboard or Spotlight -> Keyboard) -> Text, add whatever expansions you want, though this wouldn't be able to automagically figure out the actual attribution; you'd have to type that in after whatever template you set up.
