Build a desktop-first roleplay studio where writers define each character's voice, knowledge, relationships, allowed actions, and story boundaries. Separate character memory from scene history, let users inspect or delete remembered facts, and provide scene controls for fictional action, romance, pacing, and who may speak. Begin with text roleplay for verified adults and transparent safety rules rather than promising an unrestricted system.

Multiple established AI products are attracting creative roleplayers while optimizing for broad companion use and centralized moderation. That creates room for a focused writing product built around controllable characters, explicit memory management, and predictable fictional boundaries.
