AI Doc Review is a web application that helps you proofread and rewrite Chinese documents using state-of-the-art AI models. Upload a document or paste text, and the AI will detect typos, awkward phrasing, redundant expressions, and logic issues — then suggest sentence-level rewrites that you can accept or dismiss with a single click.
Access top AI models through OpenRouter with a single API key:
| Model | Highlights |
|---|---|
| Claude Sonnet 4 | Default — best balance of speed & quality |
| Claude Opus 4 | Highest accuracy |
| GPT-4.1 / o4-mini | Latest OpenAI models |
| Gemini 2.5 Pro / Flash | Google large-context models |
| Qwen 3 235B | Excellent Chinese language performance |
| DeepSeek R1 | Deep reasoning model |
| Kimi K2.5 | Moonshot's latest model |
- Typo Check — Detect misspelled or misused characters
- Tone Polish — Make stiff writing more fluent and professional
- Logic Review — Catch unclear logic and poor expression
- Conciseness — Remove redundant filler for stronger writing
- Custom Rule — Enter any proofreading requirement you need
Rules can be combined freely.
- ProseMirror Decoration-based inline highlights, color-coded by severity (red / yellow / blue)
- Click any highlighted text to open a popup with rewrite suggestions
- Right-panel suggestion list with Diff view — only actual changes are marked
- Accept or dismiss suggestions one by one, or batch all at once
- Suggestions are scoped to the minimum changed range, not the whole paragraph
- Smart paragraph-boundary chunking with configurable chunk size (1k / 2k / 5k / 10k characters)
- Parallel AI requests per chunk for dramatically faster processing
- Automatic result merging, deduplication, and offset correction
- Import:
.txt,.docxfile upload or direct text paste - Export: Download the reviewed document as TXT or DOCX
- API Key, model preference, and chunk size are stored in
localStorage— survives page refresh - Raw AI responses can be expanded for debugging
- Automatic offset correction and truncated JSON auto-repair for model output compatibility

AI Doc Review 是一款基于多模型 AI 的中文文档审校与改写 Web 应用。上传文档或粘贴文本，AI 自动识别错别字、病句、冗余表达和逻辑问题，以分句为单位给出改写建议，支持一键接受或忽略。
通过 OpenRouter 统一接入多家主流大模型，一个 Key 搞定：
| 模型 | 特点 |
|---|---|
| Claude Sonnet 4 | 默认推荐，速度与质量均衡 |
| Claude Opus 4 | 最高准确率 |
| GPT-4.1 / o4-mini | OpenAI 最新模型 |
| Gemini 2.5 Pro / Flash | Google 大上下文模型 |
| Qwen 3 235B | 通义千问，中文表现优秀 |
| DeepSeek R1 | 深度推理模型 |
| Kimi K2.5 | Moonshot 最新模型 |
- 错别字检查 — 识别拼写错误和错用字词
- 语气优化 — 将生硬表达转为流畅专业的语言
- 逻辑审查 — 检查逻辑不通和表述不清
- 简洁优化 — 去除冗余啰嗦，让表达更有力
- 自定义规则 — 输入任意审校要求
