Federico Viticci of MacStories has created S-GPT, a free shortcut that allows you to submit queries to ChatGPT. The shortcut works on iPhones, iPads, and MacOS devices, and allows integrations with the native device OS. Example: you can ask ChatGPT to create a list of songs, and S-GPT can create the playlist in Apple Music.

Using the shortcut requires a paid account and an api key from OpenAI, but as Viticci points out, he spent only $1.50 during his entire time testing the shortcut.
