>
> StoryAlter 是一款 AI 驱动的网文创作平台，让用户培养专属的「写作分身」（Alter Ego），越写越懂你。

## Core Concept

StoryAlter = Story + Alter Ego. Unlike traditional stateless AI writing tools, StoryAlter's writing alter ego has a four-dimensional personality that grows like a real creator:

- **Soul**: Core values, emotional tone, theme preferences
- **Brain**: Structure preferences, conflict design, pacing
- **Body**: Writing style, dialogue habits, description preferences
- **Experience**: Creation statistics, success patterns, style samples

The more you write, the more your alter ego understands your voice. It learns from every edit you make — if you change a paragraph, it remembers your preference.

## Key Features

### Writing & Generation
- **AI Writing Alter Ego**: Train a personal AI writing partner that learns your voice
- **Smart Outline Generation**: AI generates volume/chapter outlines based on your settings
- **Auto Chapter Writing**: One-click auto-write entire volumes, 2000-3000 words per chapter
- **AI Cover Generation**: 22 styles, one-click professional novel covers

### Character & World
- **Character Management**: Complete character profiles with personality, backstory, relationships
- **Character Chat**: Talk to your novel characters in-character — they respond based on their personality, relationships, and story progress up to the current chapter
- **Story Archive**: Centralized worldbuilding, power systems, faction management

### Intelligence Features (New in v1.1)
- **Knowledge Timeline**: After each chapter is written, AI automatically extracts character changes, relationship shifts, foreshadowing, and plot threads into a structured timeline
- **Plot Branch Simulation**: At key story decision points, AI suggests 2-3 alternative plot directions and generates ~500-word previews for each, so you can compare and choose
- **Structured Learning**: Your alter ego learns writing patterns from your edits — style preferences, pacing patterns, character voice preferences, and patterns to avoid

### Platform
- **Free Library**: Read AI-created stories for free
- **Multi-platform**: Web (storyalter.com), iOS App (App Store), Android App

你写得越多，分身越懂你。它会从你的每一次编辑中学习。
