As others have pointed out, the web page promises "cultural heritage" and "authentic stories from Africa," but the demo shows AI slop. If you're offering both, then that needs to be made more clear: highlight the authentic stories, and then make clear that users have an option to AI-generate more stories like them. If you're offering only AI-generated stories (and your words "the stories are created to cover…" make that sound possible), you need to be forthright about that, because you'll be called out, with righteous indignation, for selling AI slop as if it were a particular people's cultural legacy.
Also, speaking of "particular people," if you actually want to do something good with this project, make the provenance of each story clear and specific: not just "African," not just "West African," but "a tale from a Wolof griot, collected by Birago Diop." Africa is the largest continent of all, and its cultures are many and diverse with many different storytelling traditions.
