Humanize Chinese 2.0.0

Humanize Chinese AI Text v2.0

Comprehensive CLI for detecting and transforming Chinese AI-generated text. Makes robotic AI writing natural and human-like.

v2.0 highlights: weighted 0-100 scoring, sentence-level analysis, sentence restructuring (merge/split), context-aware replacement, rhythm variation, vocabulary diversification, 7 style transforms, external pattern config (patterns_cn.json).

Quick Start

python scripts/detect_cn.py text.txt -s           # score only
python scripts/detect_cn.py text.txt -j           # JSON output
Humanize text
python scripts/humanize_cn.py text.txt -o clean.txt
python scripts/humanize_cn.py text.txt --scene social

Detection System

Scoring

Weighted 0-100 score with 4 severity levels:

| Score | Level | Meaning | |-------|-------|---------| | 0-24 | LOW | Likely human-written | | 25-49 | MEDIUM | Some AI signals | | 50-74 | HIGH | Probably AI-generated | | 75-100 | VERY HIGH | Almost certainly AI |

Detection Categories

#### 🔴 Critical (weight: 8) | Category | Examples | |----------|----------| | Three-Part Structure | 首先...其次...最后, 一方面...另一方面, 其一...其二...其三 | | Mechanical Connectors | 值得注意的是, 综上所述, 不难发现, 归根结底, 由此可见 | | Empty Grand Words | 赋能, 闭环, 数字化转型, 协同增效, 全方位, 多维度 |

#### 🟠 High Signal (weight: 4) | Category | Examples | |----------|----------| | AI High-Frequency Words | 助力, 彰显, 底层逻辑, 抓手, 触达, 沉淀, 复盘 | | Filler Phrases | 值得一提的是, 众所周知, 毫无疑问 | | Balanced Arguments | 虽然...但是...同时, 既有...也有...更有 | | Template Sentences | 随着...的不断发展, 在当今...时代, 作为...的重要组成部分 |

#### 🟡 Medium Signal (weight: 2) | Category | Examples | |----------|----------| | Hedging Language | 在一定程度上, 某种程度上, 通常情况下 (>5 occurrences) | | List Addiction | Excessive numbered/bulleted lists | | Punctuation Overuse | Dense em dashes, semicolons | | Excessive Rhetoric | 对偶/排比句过多 |

#### ⚪ Style Signal (weight: 1.5) | Category | Description | |----------|-------------| | Uniform Paragraphs | Low CV in paragraph lengths | | Low Burstiness | Monotonous sentence lengths | | Emotional Flatness | Lack of emotional/personal expressions | | Repetitive Starters | Same sentence starters >3 times | | Low Entropy | Low character-level entropy (predictable text) |

Sentence-Level Analysis

With -v (verbose) mode, the detector identifies the most AI-like sentences:

── 最可疑句子 ──
  1. [16分] 随着人工智能技术的不断发展，在当今数字化转型时代...
     原因: 数字化转型, 深度融合, 模板: 随着.*?的(不断)?发展

Humanization Engine

Transforms (applied in order)

1. Structure cleanup — Remove three-part structure (首先/其次/最后) 2. Phrase replacement — Context-aware replacement of AI phrases (regex patterns first, then plain text, longest-first matching) 3. Sentence merge — Merge overly short consecutive sentences 4. Sentence split — Split long sentences at natural breakpoints (但是/不过/同时) 5. Punctuation normalization — Reduce excessive semicolons, em dashes 6. Vocabulary diversification — Replace repeated words (进行/实现/提供 etc.) with synonyms 7. Paragraph rhythm — Vary uniform paragraph lengths (merge short, split long) 8. Casual injection — Add human expressions (scene-dependent) 9. Paragraph shortening — For social/chat scenes

Scenes

| Scene | Casualness | Best For | |-------|-----------|----------| | general | 0.3 | Default, balanced | | social | 0.7 | Social media, short posts | | tech | 0.3 | Tech blogs, tutorials | | formal | 0.1 | Formal articles, reports | | chat | 0.8 | Conversations, messaging |

Aggressive Mode (-a)

Adds +0.3 casualness, more colloquial expressions, stronger sentence restructuring. Typical score reduction: 60-80 points on heavily AI-generated text.

Reproducibility

Use --seed N for reproducible results (same input + seed = same output).

Writing Style Transforms

7 specialized Chinese writing styles:

| Style | Name | Description | |-------|------|-------------| | casual | 口语化 | Like chatting with friends — natural, relaxed | | zhihu | 知乎 | Rational, in-depth, personal opinions | | xiaohongshu | 小红书 | Enthusiastic, emoji-rich, product-focused | | wechat | 公众号 | Storytelling, engaging, relatable | | academic | 学术 | Rigorous, precise, no colloquialisms | | literary | 文艺 | Poetic, imagery-rich, metaphorical | | weibo | 微博 | Short, opinionated, shareable |

Combine humanize + style

python scripts/humanize_cn.py text.txt --style xiaohongshu -o xhs.txt

This first humanizes (removes AI patterns) then applies the style transform.

External Configuration

All patterns, replacements, and scoring weights are in scripts/patterns_cn.json. Edit this file to:

Scripts Reference

detect_cn.py

python scripts/detect_cn.py [file] [-j] [-s] [-v] [--sentences N]

| Flag | Description | |------|-------------| | -j | JSON output | | -s | Score only (e.g. "72/100 (high)") | | -v | Verbose: show worst sentences | | --sentences N | Number of worst sentences to show (default: 5) |

humanize_cn.py

python scripts/humanize_cn.py [file] [-o output] [--scene S] [--style S] [-a] [--seed N]

| Flag | Description | |------|-------------| | -o | Output file | | --scene | general/social/tech/formal/chat | | --style | casual/zhihu/xiaohongshu/wechat/academic/literary/weibo | | -a | Aggressive mode | | --seed | Random seed for reproducibility |

style_cn.py

python scripts/style_cn.py [file] --style S [-o output] [--seed N] [--list]

compare_cn.py

python scripts/compare_cn.py [file] [-o output] [--scene S] [--style S] [-a]

Shows score diff, category changes, and metric comparison before/after humanization.

Workflow

# 1. Check AI score
python scripts/detect_cn.py document.txt -v
2. Humanize with comparison
python scripts/compare_cn.py document.txt --scene tech -a -o clean.txt
3. Verify improvement
python scripts/detect_cn.py clean.txt -s
4. Optional: apply specific style
python scripts/style_cn.py clean.txt --style zhihu -o final.txt

Batch Processing

# Scan all files
for f in *.txt; do
  echo "=== $f ==="
  python scripts/detect_cn.py "$f" -s
done
Transform all markdown
for f in *.md; do
  python scripts/humanize_cn.py "$f" --scene tech -a -o "${f%.md}_clean.md"
