What RisuAI is

RisuAI is a free, open-source AI roleplay client for creating characters, chatting with AI characters, and building custom AI worlds. It runs on Android, Linux, macOS, Windows, and the web, and can also be self-hosted. RisuRealm lets users share characters and worlds. Advanced tools include emotion images, custom prompt templates, inlaid images, prompt injection, and persistent memory. Chat options listed by the project include group chats, plugins, regex scripts, translation, lorebooks, themes, text-to-speech, and image, audio, and video assets. HypaMemoryV2/V3 provide memory compression, while SupaMemory supports long-term conversation context. Supported APIs include OpenAI, Claude, Gemini, DeepInfra, Ooba, and OpenRouter, among others. Docker instructions support web hosting at localhost:6001. Plugins run in a sandbox with iframe isolation and restricted application-DOM access; some permissions require consent. The privacy policy lists access controls and encryption.
