SoulFun AI is a consumer-facing AI companion and virtual-dating style app that focuses on emotionally-responsive, story-driven conversations with customizable characters. Users can choose from a catalog of predefined personas or design their own characters (appearance, personality, hobbies and backstory) and engage in persistent, branching interactive storylines where responses and choices influence subsequent interactions.

Core features include real-time text chat, voice-chat capabilities, emotional/contextual response handling, profile-style character discovery, and tools to build and personalize AI companions. The platform emphasizes sustained, immersive interactions with characters that learn from ongoing conversations to tailor replies and deepen perceived rapport. SoulFun also supports multimedia interactions and timed features such as voice and video calls gated behind in-app currency or subscription tiers.

For developers and integrators, SoulFun provides a documented API with authentication, messaging endpoints, and response retrieval to embed SoulFun conversational agents into other applications. The service is monetized through a freemium model: a free tier or free access to basic chat plus a paid Premium subscription that grants extra coins, the ability to create custom characters, access to photos and paid call minutes, and other premium capabilities. The typical audience includes adults seeking companionship, roleplay or adult-oriented conversational experiences, social/entertainment app users, and developers who want to add emotionally-aware chat characters to their products.
