So this was fake, but I imagine there's a market for LLMs/chat bots trained on specific books - particularly self-help and life coaching books.

I imagine many of the purchasers of Tony Robins or Gary Vaynerchuk books or seminars would pay for a life coach app/service, particularly if it could speak in their voice (trained from audiobook narration)

This AI from Arnold beat some new LLM models (Llama2, Gpt 3.5...)
