Repin — AI Character Chat

Acerca de esta app

Repin is an iOS application developed by SEONHEE AN designed for interactive storytelling through AI-generated characters. The app centers on a ‘Character Wizard’ that allows users to build custom personas in under a minute by answering simple questions, with options for fine-tuning names, personalities, and generated art. A key differentiator is its memory system, which automatically tracks conversations, relationships, and key moments to ensure continuity without requiring user recaps or summaries. Users can generate scene-specific images and share their creations with the community. The platform emphasizes privacy, storing chats securely with encryption in the cloud. It targets creative writers, fans of novels and webtoons, and users seeking personalized, long-form AI interactions.
