Federico Viticci's S-GPT is doing some pretty neat things using Shortcuts

Some examples from that blog post:
> I’m feeling nostalgic. Make me a playlist with 25 mellow indie rock songs released between 2000 and 2010 and sort them by release year, from oldest to most recent.
This doesn't just return a list of songs, it will create the playlist for you in Music.
> Check the paragraphs of text in my clipboard for grammar mistakes. Provide a list of mistakes, annotate them, and offer suggestions for fixes.
> Summarize the text in my clipboard
> Go back to the original text and translate it into Italian
I haven't tried it myself, but it has other integrations like "live text" where your phone can pull text out of an image and then could send that to GPT to be summarized.
Version 1.0.2 makes improvements for using it via Siri including on HomePod.
