Personalized bed stories for kids

Hey,

I'm the middle of my MVP for a very basic website in which you just input a topic describing a main story and using AI to generate a 4-5 page book for kids to read before sleeping.

The solution would save older books, and the book generated would complete, ie with illustrations, title, cover, ... and presented in a funny way in the website (animated paging, bring book from bookshelf with animation ..).

I'm really in the last step ( I did the wrong thing starting from actual implementation, cuz I wanted it to my kids at least).

I think of releasing it as free trial, for example free 5 tokens / month (1 token = 1 book).

BUT do you really see yourself paying like 10 e/month (unlimited books) for such service ?

Thanks in advance for your precious feedback.
