AI roleplay (LLM)
AI roleplay is the use of language models for interactive fiction, character chat, and collaborative storytelling — usually with a persistent character persona maintained across many turns.
AI roleplay grew from a niche use case to a major consumer category by 2026, driven by Character.ai, Replika, Janitor AI, and direct LLM use via NovelAI / OpenRouter. The technical challenges: maintaining character consistency across long conversations, handling sensitive content thoughtfully, balancing creativity with policy, and supporting users emotionally without crossing into harm. Production roleplay systems combine fine-tuned models, character cards as system prompts, persistent memory layers, and content-safety guardrails. The ethical and welfare conversation around AI roleplay is ongoing — particularly for vulnerable users.
