Using AI to sell info products?

I wrote my first ebook about the method I discovered that helped me easily and quickly quit a long term smoking/vaping habit with no weight gain and it turned out good and look professional. I really believe this book has huge potential as there is nothing else like it out there that uses this approach, but I put it on Gumroad and Amazon and have only made a few sales in the past year, I assume due to the number of competing books on the subject. I haven't done much marketing due to budget constraints.

I keep seeing posts on X about using AI to create viral content to sell products and they claim to be making tons of money. My question is would it be worth it to try to create an AI influencer to sell my ebook on Instagram, TikTok and X? What are the best sites or apps to use for that? What are the best practices I should be using to get sales going? Thanks
