ChatGPT and Storyline User Input

Hi, 

Does anyone know how to have AI analyze user text input in Storyline, on the slide and starting from a prompt?

Our learners do a lot of writing, so I'd like our courses to provide customized feedback on their samples. I really want to get away from, "Click here to compare your answers with [insert job title]."  So, I want to include AI for that. However, I want to add the prompt first so AI is targeting what our organization wants--not just generic writing tips. I've scoured the internet and watched Devlin Peck's video on adding ChatGPT. It's a good start, although it didn't work on our end. Plus, that would just grab a response from ChatGPT without our prompt considerations. (A few weeks ago, I saw a video about having a button that adds the prompt before the user enters their info and clicks submit. I can't find that site in my history.)

If not, is there a workaround other than having them open ChatGPT and inputting the prompt themselves? 

Side note: We've tried other AI mechanisms, such as IBM Watson. Nothing was working on our end. We spent a lot of time troubleshooting and are continuing to look into it.

Much appreciated!
