AIEro is a hentai-style AI roleplay platform organizing content around predefined scenarios rather than a roster of individual characters. At time of review, nearly 600 scenarios were available, organized into categories including Mainstream Fetish, Niche Fetish, Fantasy World, and Science Fiction. New users receive 20,000 free credits. Additional credits cost $2 per 75,000, with no recurring subscription tier — all spending is credit-based. The platform offers approximately 200 AI chat models at varying costs per message, including commercial models such as GPT-5, Grok-3, and Claude. Not all models support explicit content; the reviewer had to switch models to unlock NSFW responses. Voice synthesis and prompt-based image generation are available as add-ons. The mod customization interface and voice selection menus were in Chinese without auto-translation at time of review. Image generation was inconsistent, sometimes requiring multiple model switches to return explicit results. Best fit for users who prefer scenario-driven roleplay over character-driven chat, with tolerance for platform rough edges.
