A Raycast extension I contributed to

 I contributed a couple of commands to the excellent Raycast app and command launcher (similar to Alfred). The commands are called Transform and Transform Preview and are in the ChatGPT Quick Actions extension (needs a ChatGPT User API key).

Basically you select some text anywhere, do ⌥ Space to bring up Raycast, then select Transform and give it a prompt to act on and replace the selected text, like:

• beautify JSON
• do the math
• count the occurrences of each line

Transform Preview displays the result in a window instead of replacing the selected text.
