## What is Kaite-nka?
"Kaite-nka" is a specialized writing tool for novelists and game scenario writers. It is completely **free to use** and requires **no installation**—everything runs entirely in your web browser. Unlike simple text editors, it integrates project management, version control, and world-building tools into a single, powerful interface.

## Core Capabilities

### 1. Unified Writing Environment
- **Vertical & Horizontal Writing**: Full support for Japanese vertical writing (Tategaki) with real-time switching.
- **Scenario Mode**: Specialized editor mode for game scripts with character name auto-completion and dialogue formatting.
- **Novel Mode**: Distraction-free writing environment optimized for long-form fiction.

### 2. World Building & Management
- **Integrated Database**: A Notion-like database system to manage characters, locations, items, and plot points directly alongside your manuscript.
- **Idea Board**: Kanban-style board for organizing plot points, scenes, and loose ideas.
- **Auto-Suggest**: Character names and terms defined in your database are automatically suggested while typing.

### 3. Professional Version Control
- **Git Integration**: Built-in full Git client. Commit, push, pull, and manage branches directly from the browser without command-line knowledge.
- **History & Diff**: visual diff tool to track changes and revert to previous versions safely.

### 4. Production Ready
- **Scenario Emulator**: Instant preview of how your text looks in a visual novel game engine, checking rhythm and line breaks.
- **Proofreading**: Real-time checking for common errors, typos, and consistency issues.
- **Export**: One-click export to Excel (.xlsx) for Unity/Unreal Engine integration, or standard text formats for publishing.
