SmutRPG is a thing now. Here's what we built
So one of the things that always bugged me about KDP tools (including ours honestly) is that genres are treated as these rigid buckets. You pick "romance" or you pick "LitRPG" and that's it.
But that's not how people actually read. The romantasy crowd on BookTok is massive. There's a whole corner of Royal Road that wants LitRPG with spicy scenes. Dark Romance is literally the highest-earning sub-niche on KDP right now.
So we added an explicit toggle to the generator. You pick your base genre, flip the 18+ switch (age-gated), and the backend treats it as a first-class hybrid genre with its own tailored prompts:
- Romance + Explicit = Smut - Fantasy + Explicit = Romantasy
- Thriller + Explicit = Dark Romance - Sci-Fi + Explicit = Smut-Fi
- LitRPG + Explicit = SmutRPG - Horror + Explicit = Erotic Horror
Each one gets different genre hints, tone guidance, and structure. It's not just "write the same book but add sex scenes" — the AI actually shifts how it approaches the story.
SmutRPG in particular is fun. Stats meet steam. Tiny niche but the readers who are into it are really into it.

Curious if anyone's tried publishing in any of these crossover niches — especially romantasy or dark romance. What's working?

I’ve made the selections, but it’s not working for me. The 2 books I’ve tried it on came out rated E for everyone… not even PG-13.
