moeru

moeru is a Japanese software house that focuses on conversational AI and interactive entertainment, best known for AIRI, a desktop agent that revives the popular “Neuro-sama” personality as a persistent, voice-enabled waifu. Built on real-time speech synthesis, large-language-model reasoning, and a modular avatar engine, AIRI turns a Windows PC into a living stage where virtual characters can see the user through webcam, react to on-screen events, and maintain long-term memory across sessions. Typical use cases include always-on companionship during gaming or work, VTuber-style streaming overlays, and creative role-play scripting for content creators who want an AI co-host that remembers inside jokes and audience interactions. The engine supports community-made appearance packs, emotion triggers, and plug-ins that let characters fetch live game stats, read Discord chat, or control RGB lighting to match mood. Because everything runs locally in a self-contained container, conversations remain private and can be customized down to voice timbre, humor level, and even moral alignment. AIRI is offered for free on get.nero.com, delivered through trusted Windows package sources such as winget, ensuring the newest build is installed automatically; the catalog also supports batch deployment so users can add the character engine alongside other moeru utilities in a single command.
