I built a travel-planning site over Christmas: https://www.daystodo.com/

I'm planning on posting a blog about my experience here at some point, but it was fun. You can find a draft of it on the site if you're interested in my thoughts on using it as datasource for an app.

Basically, I agree - you need to use DaVinci to get good results and it's expensive. That means restricting the amount of queries a user can make (I do it through restricting the inputs a user has) and saving the results, so other users get the saved results instead of hitting OpenAI.

For more free-form inputs, I think the only option is to make users pay a small fee (which is tough, because even DaVinci struggles sometimes and I don't want users paying for errors). I'm also experimenting with AdSense but I doubt it'll cover the costs.

I wouldn't say I plan to 'make money' but with luck it might be my first side-project that will break even
