Joi AI
Pros
- + Boundary memory tracks your limits and never pushes past them without explicit opt-in
- + Three intensity modes (soft, medium, explicit) let you dial the heat precisely

Cons
- - 115-character message cap constrains roleplay descriptions to almost nothing
- - Boundary system over-corrects: characters refuse NSFW scenarios mid-session even on premium
