Since AI got good at this type of SaaS, I now look if something is worth it for

1. Originality (did I come up with it before? this is my definition for it, and I am not very original)

2. (Re)build value

3. Lifetime maintenance / hosting value

Given these factors, I would say you should ask $9.99/year for it and people would probably go for it with enough exposure.

i really liked your take on this and would work on implementing it
