# Virtual Kimi - AI Companion Application 💖

Web-based AI companion girlfriends featuring adaptive personalities, intelligent memory systems, and immersive conversational experiences.

## Overview

Virtual Kimi is an advanced virtual companion application that combines modern web technologies with state-of-the-art AI models to create meaningful, evolving relationships between users and AI girlfriend personalities.

- **Lightweight:** ~600 KB of pure JavaScript, HTML, and CSS (no frameworks)
- **Local-first:** All data is stored in your browser's IndexedDB (managed by Dexie.js)
- **No tracking:** The only external calls are to FontAwesome (for icons) and the OpenRouter API (for AI)

Built with vanilla JavaScript and modern web APIs, it offers a rich, responsive experience across devices.

## ✨ Inspiration & Assets

This project was originally inspired by the [JackyWine GitHub repository](https://github.com/Jackywine).
@Jackywine on X (Twitter)

The four main characters are visually based on images from four creators on X (Twitter):

- @JulyFox33 (Kimi)
- @BelisariaNew (Bella)
- @JuliAIkiko (Rosa and Stella)

All character videos were generated using the image-to-video AI from Kling.ai, specifically with the Kling v2.1 model.

### Data Flow

1. **Input Processing**: User input → Security validation → Language detection
2. **AI Analysis**: Emotion detection → Memory extraction → LLM processing
3. **Response Generation**: Personality-aware response → Emotion mapping → Visual selection
4. **Memory Update**: Trait evolution → Memory storage → UI synchronization

## Installation & Setup

### Prerequisites

- Modern web browser (Chrome, Edge, Firefox recommended)
- OpenRouter API key (optional but recommended for full functionality)

### Quick Start

1. **Clone the repository**

    ```bash
    git clone https://github.com/virtualkimi/virtual-kimi.git
    cd virtual-kimi
    ```

2. **Open the application**

    - Open `index.html` in your web browser
    - Or serve via local web server for optimal performance:
        ```bash
        python -m http.server 8000
        # Navigate to http://localhost:8000
        ```

3. **Configure API access**

    - Open Settings → AI & Models
    - Add your OpenRouter API key
    - Select preferred AI model

4. **Customize your experience**
    - Choose a character in Personality tab
    - Enable memory system in Data tab
    - Adjust themes in Appearance tab

### Production Deployment

For production deployment, ensure:

- HTTPS is enabled (required for microphone access)
- Gzip compression for assets
- Proper cache headers
- CSP headers for enhanced security

## ⚙️ Configuration

### API Integration

The application supports multiple AI providers through OpenRouter:

- Mistral models
- Nous Hermes models
- Qwen3 models
- Open-source alternatives

### Memory System Configuration

```javascript
// Memory categories can be customized
const memoryCategories = [
    "personal", // Personal information
    "preferences", // Likes and dislikes
    "relationships", // People and connections
    "activities", // Hobbies and activities
    "goals", // Aspirations and plans
    "experiences", // Past events
    "important" // Significant moments
];
```

### Adding New Features

#### Creating a New Plugin

```javascript
// manifest.json
{
    "name": "Custom Theme",
    "version": "1.0.0",
    "type": "theme",
    "style": "theme.css",
    "main": "theme.js",
    "enabled": true
}
```

> **Note:** As of version 1.0, only the color theme plugin is fully functional. Voice and behavior plugins are planned for future releases. See `kimi-plugins/sample-theme/` for a working example.

#### Extending Memory Categories

```javascript
// Add to kimi-memory-system.js
const customCategory = {
    name: "custom",
    icon: "fas fa-star",
    keywords: ["keyword1", "keyword2"],
    confidence: 0.7
};
```

### Health Check System

The application includes a comprehensive health check system:

```javascript
// Run health check
const healthCheck = new KimiHealthCheck();
const report = await healthCheck.runAllChecks();
console.log(report.status); // 'HEALTHY' or 'NEEDS_ATTENTION'
```
