Oshikoi is an immersive 3D AI companion chat app: your Mate is not a static picture but a 3D avatar with real-time facial expressions, body gestures and lip-sync, reacting with a smile or a head tilt as you talk — far more present than plain text. It supports mainstream models like GPT, Claude and Gemini, plus the built-in OshiLM; you can import VRM models from VRoid Hub or VRChat to build a truly personal companion, or explore community-made 'Community Mates'. The Mate has long-term vector memory that recalls your preferences and past moments across sessions; beyond emotional companionship it can check the weather, search the web and update your calendar. Basic chat is free forever; voice cloning, multi-device cloud sync and third-party AI access are membership features. It covers 16 languages and offers a Chrome extension to keep your Mate one click away. Official site: oshikoi.io.
Background
OshiKoi is a 3D AI companion chat app centered on a Mate that moves and remembers you. It launched on iOS in June 2026 and also offers Android and Chrome extension versions, marketing itself as filter-free, multilingual and low-interruption.
Technology
Oshikoi blends mainstream models (GPT, Claude, Gemini) with its in-house OshiLM, using AI Motion for real-time expressions and gestures, Voice Cloning for custom voices, and Vector Memory to retain key moments across sessions; it supports VRM model import and Community Mate sharing.
Market
It differentiates in the AI companion space via '3D avatar + real-time motion + long-term vector memory + deep customization', targeting anime-loving users who want a tangible sense of companionship and value relationship continuity, with free basic chat and a membership for advanced features.
Best For
People who want a 3D companion that moves and remembers themAnime fans who want to build or import their own VRM 3D charactersUsers wanting portable emotional companionship plus small helpers like weather and calendarAnyone who values long-term memory and relationship continuity, not starting fresh each time
Editorial Note
Turns an AI companion into a 3D avatar that moves and remembers you; immersion and customization are the highlights, though high-fidelity 3D demands phone performance and advanced features need membership.
