What RisuAI is
RisuAI is a free, open-source AI roleplay client for creating characters, chatting with AI characters, and building custom AI worlds. RisuRealm lets users share characters and worlds. The project supports Android, Linux, macOS, Windows, web use, and self-hosting, with native mobile apps available. Listed model connections include OpenAI, Claude, Gemini, DeepInfra, Ooba, and OpenRouter. Chat capabilities include group conversations, plugins, regex scripts, translation, lorebooks, themes, text-to-speech, and image, audio, and video assets. Character tools include emotion images, custom prompt templates, inlaid images, and prompt injection. Persistent conversation memory uses HypaMemoryV2/V3 compression and SupaMemory. Docker instructions support self-hosted web deployment 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. RisuRealm provides email and Discord support, reports, and feedback links.
