Your GPT4 key + My AI article tool

I've been testing content creating with GPT4, while the content improvement itself isn't significant, it certainly flows and listens to instructions very well. This enables articles to be created which are a cut above the rest of the mass produced AI articles. I want to create ~100 with gpt4 per blog site which will cost approx $20. I'm happy to bear the cost or split it.

I have some old domains that index articles without issue. I'm not an SEO expert so may require help with keyword research.
