Finding out legal risks is overall good for any product you plan to make. I wouldn’t demonize technology just because it’s in “AI” category. It is kind of hot topic atm, but there are multitude of AI-based products out there that are being made and sold for years (from text-to-speech engines, through auto-captioning services to… photoshop).
I wouldn’t go for chatgpt though as it’s not intended atm to be integrated. Might get even banned for it. And it will be paid service soon. But one could easily connect to OpenAI API and use gpt3 directly.
