OPC Wave 1 Snapshot

Item	Yorimi Summary
Track	Digital Culture - AI+Entertainment / AI+Education
Stage	Wave 1: Idea / Specs - scenario definition, business logic, executable requirements, and evaluation criteria
Core scenario	Users create or select an AI character for ACGN, VTuber, indie game IP, original character, digital pet, study, and daily companionship scenes. Yorimi gives the character persona-consistent dialogue, lightweight memory, emotional/state feedback, micro-action guidance, and 3D desktop presence.
Evaluation criteria	Persona consistency, onboarding completion, low-motivation response quality, memory usefulness, desktop-presence effect, creator interest, and early payment signal. Full criteria are in 01_Project_Specification_EN.md.
Current demo status	Web runtime prototype is deployed on the predecessor Compagnon Éveil domain and can run locally from this repo. Physical 3D desktop device proof is shown below. Creator Studio is a planned Wave 2/3 creator-side prototype, not claimed as a shipped feature.

Demo domain note: Yorimi was previously named Compagnon Éveil, so the current live demo URL is still https://compagnon-eveil.vercel.app/. The repo, specs, and product direction are now Yorimi.

One-Line Pitch

Yorimi is building the AI presence layer for digital characters, giving virtual IPs memory, agency, and real-world 3D desktop embodiment beyond the screen.

What Is Yorimi?

Yorimi is an AI character presence product that combines:

• AI character interaction
• Long-term memory and session context
• Voice and emotional state feedback
• Study, work, routine, and daily companionship
• Planned Creator IP interaction through Creator Studio
• 3D desktop companion device presentation

It is designed for ACGN users, VTuber communities, indie game IPs, original character creators, and young users who want study and daily companionship. Yorimi fits the Digital Culture track as an AI+Entertainment / AI+Education application.

Why The Demo Link Says Compagnon Éveil

Yorimi was previously named Compagnon Éveil. The current deployed technical prototype still uses the predecessor deployment domain:

https://compagnon-eveil.vercel.app/

The product identity, Wave 1 submission, and future roadmap are now Yorimi.

Product Experience

Users create or select an AI companion: an original anime-style character, study companion, VTuber character, indie game character, or digital pet. Each character can have personality, voice interaction, memory, skins, and expressive states.

When the user feels stuck, low-energy, or unable to start, Yorimi responds gently first, then guides one concrete action such as a daily check-in, a 10-minute study sprint, or a task-start reminder.

Unlike a normal chatbot, Yorimi also has a 3D desktop companion device demo. The character can appear on a physical desktop display with expressions, motion, and status, turning virtual characters into companions with real-world presence.

Creator Studio

Yorimi is planned to provide Creator Studio for VTubers, illustrators, indie game teams, and original IP creators. In Wave 2/3, creators will be able to upload character settings, worldview boundaries, tone samples, voice, and skins, turning their characters into interactive, operable, displayable, and monetizable AI character services.

Current Status

Wave 1 is focused on clear product specs: application scenarios, business logic, executable requirements, and evaluation criteria.

Current repository includes:

• Deployed Web runtime prototype
• OpenAI runtime adapter
• Schema-compatible fallback behavior
• Voice fallback
• Session and lightweight memory logic
• Companion assets
• 3D desktop device demo assets
• Chinese and English submission documents

This is not yet a complete commercial product. Wave 2 will turn the current runtime into a Yorimi-branded MVP.

The local route keeps the predecessor filename for deployment compatibility. Yorimi is the current product identity.

Run Locally

For live AI, set:

OPENAI_API_KEY=your_key_here
USE_MOCK_AI=false

Without OPENAI_API_KEY, the backend uses schema-compatible fallback for frontend rendering and failure-handling tests. Real character quality should be evaluated with OpenAI configured.

项目定位

Yorimi 是一款结合 AI 角色互动系统 与 3D 桌面陪伴设备 的 AI 角色存在产品，面向 ACGN、VTuber、独立游戏 IP、原创角色创作者与年轻用户，属于数字文化赛道的 AI+文娱 / AI+教育 应用。

用户可以创建或选择一个 AI companion，例如原创二次元角色、学习陪伴角色、VTuber 角色、独立游戏角色或数字宠物。角色具备可对话的性格、语音互动、长期记忆、角色皮肤与情绪化表达，能在学习、工作和日常生活中提供陪伴、提醒、鼓励与轻量行动引导。

当用户感到低动力、拖延或难以开始时，Yorimi 会先温和回应，再引导用户完成一个具体的小行动，例如每日 check-in、10 分钟学习专注或任务开始提醒。

3D 桌面在场

与传统 AI 聊天工具不同，Yorimi 不止于文字回复。我们已经制作了 3D 桌面陪伴设备 Demo，让角色在桌面设备上展示表情、动作与状态，赋予虚拟角色现实存在感。它把 AI 对话、角色设定、长期记忆、视觉形象、桌面展示与陪伴场景结合起来，让虚拟角色成为有持续互动价值的数字伙伴。

创作者端

Yorimi 计划在 Wave 2/3 提供 Creator Studio，支持 VTuber、画师、独立游戏团队与原创 IP 创作者上传角色设定、世界观边界、语气风格、语音与皮肤，把自己的角色转化为可互动、可运营、可展示、可商业化的 AI 角色服务。当前阶段将 Creator Studio 定义为创作者端产品方向与后续原型目标，而不是已上线功能。

当前阶段

本阶段项目仓库包含产品说明、代码运行说明、技术与产品架构、未来规划、团队介绍、线上技术原型与 3D 桌面设备展示素材。Yorimi 的前身项目 Compagnon Éveil 曾入选 UCWS Singapore Hackathon 2026 Top 20 Finalist；当前我们正基于前期 Demo 与反馈，将项目进一步升级为定位更清晰的 AI 角色存在产品。
