My Copywriting-GPT-3-App vs. the big boys

Hey folks! :)

I'm working on a GPT-3-based copywriting-companion. I'd be very interested what you think of the idea! In its essence, the companion should assist copywriters during brainstorming and provide feedback on the created content.

When working with it, the workflow would look something like this:

1. Type in basic information about a product/topic
2. GPT-3 generates copies
3. Generate again or pick out the copy you liked most
4. Let GPT-3 take the position of a potential customer that asks (critical) questions
5. In case GPT-3 touches on some important topics that you can make use of for a better copy: Improve copy
6. Let GPT-3 ask again and improve until no relevant pain points etc. are left unaddressed

Here's a 2 min demo: https://www.youtube.com/watch?v=P-T3sdsuBHs

Copywriting is a very popular use case for GPT-3-Apps and it seems like two companies (copy.ai and copysmith.ai) are getting ever-more dominant in this niche. However, I hope that the feedback-loop-feature is somewhat gamifying the experience and making it more fun to use than the competition's "generate-only" implementations. Comparing the idea & demo with copy.ai and copysmith.ai, do you think my app stands a chance? And if not, where do I have to improve most?
