How do you allow non-technical folks to edit prompts?

I feel like many companies probably have this problem: you have a bunch of prompts in your codebase and you want to allow non-technical folks to edit or iterate upon them to make them better.

In our case, we help our customers with local SEO so we hired someone to help us refine them. He's great at prompting and SEO but does not code.

So we need a playground like environment, except that takes in different records from our database as params and that uses structured JSON outputs.

Is there a company tackling this? Would happily use them if so! If not, startup idea!
