Why AI Translators Feel Mechanical and This Tool Makes PDFs Read Like Chinese

Problem with Existing AI Translators

Most AI translation tools generate word‑for‑word results that retain English sentence structure and grammar, giving the output a distinct "machine‑translation" flavor. Issues include Euro‑style Chinese, inconsistent terminology, and lack of style adaptation for different document types.

What Cuimao Translator Does

The open‑source project Cuimao Translator (a Claude Code skill) addresses these problems by first analyzing the source text’s style, tone, and domain, then deciding how to express it naturally in Chinese instead of directly feeding the raw text to an LLM.

Three Translation Modes

⚡ Quick (速译) – Trigger words: 快翻, 速译. Intended for rapid browsing and getting the gist.

📖 Normal (标准) – Default mode. Suitable for most book chapters, blogs, and general content.

💎 Refined (精翻) – Trigger words: 精翻, 精细翻译. Used for publication‑grade output, key chapters, and final delivery.

In Refined mode the pipeline follows five steps: analysis → first draft → proofreading → revision → polishing. Users can upgrade from Normal to Refined mid‑process by replying “继续润色”.

Five Built‑in Style Presets

📝 storytelling – For novels, biographies, and narrative nonfiction. Emphasizes smooth flow, vivid language, and Chinese rhythm.

🎓 academic – For scholarly works, textbooks, and research reports. Uses formal register, precise terminology, and proper citation style.

⚙️ literal – For technical manuals, legal documents, and contracts. Stays close to the original structure with minimal rewriting.

✨ elegant – For literary fiction, poetry, and prose. Applies four‑character idioms, aesthetic sound patterns, and deliberate pauses.

💬 conversational – For dialogue‑heavy books, self‑help guides, and memoirs. Produces a relaxed, chat‑like tone.

If no style is specified, the tool automatically selects the most appropriate one; for most narrative books it defaults to storytelling.

Translation Philosophy: Faith → Fluency → Elegance

Faith (忠实) – Every English sentence must have a corresponding Chinese sentence with identical facts, numbers, and proper nouns; no omission or embellishment.

Fluency (流畅) – Chinese should read as native prose, reorganizing topics and comments, breaking long sentences into natural 7‑15 character chunks, and favoring active constructions.

Elegance (雅) – Cultural references, idioms, and slang are rendered with equivalent Chinese expressions; untranslatable wordplay is annotated, and foreign citations receive brief explanations.

Six Checks for Euro‑Style Chinese

1. Overuse of passive “被” constructions – e.g., "He was praised" → "他受到表扬".

2. Stacked conjunctions – e.g., "因为…所以…" or "虽然…但是…" are re‑ordered to follow natural Chinese logic.

3. Overly long attributive clauses – split into multiple short sentences.

4. Misuse of "之一" – decide contextually, often translating "one of the most…" as "极其".

5. Repetitive "的" – restructure the whole sentence to avoid three or more consecutive "的".

6. Excessive nominalization – replace "the implementation of…" with the verb form "实施…".

Real‑World Example

Original English: The old man had taught the boy to fish and the boy loved him. He was an old man who fished alone in a skiff in the Gulf Stream and he had gone eighty‑four days now without taking a fish.

Storytelling output: 老头儿教过那孩子打鱼，孩子也爱他。他是个独自在湾流里的一只小船上打鱼的老头儿，如今已经接连八十四天一条鱼也没打着了。

The result reads naturally, with colloquial expressions like “老头儿”, a temporal sense “如今已经…了”, and the idiomatic phrasing “八十四天一条鱼也没打着”.

Built‑in Terminology Table

The tool ships with a bilingual glossary of over 100 common terms covering computer science, AI, business, and law, ensuring consistent terminology throughout a book. Users can extend the table as needed.

Quick Start

# Install into Claude Code
git clone https://github.com/Cuimao777/cuimao-translator.git ~/.claude/skills/cuimao-translator
# Restart Claude Code and say:
# "翻译这个 PDF"
# or "精翻 Chapter 3"
# or "快翻这段内容"

No API key configuration is required; the skill works directly inside Claude Code.
