🇨🇳 Mandarin Chinese AI Humanizer

Smoother Mandarin Chinese From Your AI-Assisted Draft

SupWriter's AI humanizer rewrites AI-assisted Mandarin Chinese with fresh wording and sentence structure; the sample below is one run in simplified characters, shown exactly as the tool returned it. In mainland China, some universities now screen graduation theses for AI-generated content: in 2026, Shandong University of Technology's computer science school ran all of its undergraduate defence drafts through an AIGC check in CNKI's thesis system and put those scoring above 40% on a warning list.

在当今社会，人工智能在高等教育的领域中得到了日趋显著的应用。首先，人工智能能为每个孩子设计个性化学习方案，让他们的学习内容合自己孩子的特点至关重要。而通过人工智能技术，学生根据自己的学习发展程度进行调整是完全可以做到的。智能辅导系统可以及时解答学生的提问，从而提升学习的效率。例如，学生的作业批改和成绩分析等工作，都可以交由人工智能去完成。这样，老师就有更多时间去专心于教学本身。人工智能的崛起虽然给学术带来了很多积极的影响，但并不意味着没有消极影响，反而人工智能的发展带来了很多学术不诚实与数据隐私等各种危害。总而言之，只有合理、规范地使用人工智能，才能真正推动高等教育的高质量发展。

English gloss: In today's society, artificial intelligence is being applied ever more prominently in the field of higher education. First, AI can design a personalized learning plan for every child; making their learning content suit the traits of their own child is essential. And through AI technology, it is entirely possible for students to make adjustments according to their own level of learning progress. Intelligent tutoring systems can answer students' questions promptly, thereby improving the efficiency of learning. For example, tasks such as marking students' homework and analyzing their grades can all be handed over to AI. That way, teachers have more time to concentrate on teaching itself. Although the rise of AI has brought many positive effects to academia, that does not mean there are no negative effects; on the contrary, the development of AI has brought all kinds of harms, such as academic dishonesty and data privacy. In short, only by using AI sensibly and in line with proper standards can we truly advance the high-quality development of higher education.

Thesis rules on AI: mainland China and Taiwan

Mainland China. Article 37 of the Degree Law, in force since 1 January 2025, says a degree is not conferred, or is revoked, if the thesis is found to involve ghostwriting (代写), plagiarism (剽窃), fabrication (伪造) or similar misconduct [1]. Under Article 39, the student must first be told the facts, reasons and legal basis and be heard [1]. The August 2023 draft named “AI ghostwriting” (人工智能代写) outright [2], but the adopted text doesn't mention AI [1], which leaves AI rules to each university.

Shandong University of Technology's School of Computer Science ran an AIGC check on every 2026 undergraduate defence draft in CNKI's graduation-thesis system [3][4]. It banned using large AI models to directly generate a thesis's core content, such as the abstract, methods and conclusions [4]. Drafts above 40% went on a warning list: supervisors decided whether they could proceed, grades were capped at “good” (良好) and reviewers' marks had to stay below 80 [3].

Taiwan. Under Article 17 of the Degree Conferral Act (學位授予法), a university must revoke a degree if the thesis involved plagiarism, being written by someone else (由他人代寫) or other fraud, and Article 18 fines anyone who advertises or provides thesis ghostwriting NT$300,000 to NT$1,000,000 per violation [5]. National Taiwan Normal University's 2026 AI guideline lets each teacher encourage, limit or bar AI in a course, requires students to disclose the tool, its version, how they used it and its role, and forbids submitting work produced wholly or mainly by AI [6].

Who can score Chinese for AI, and why our sample has none

Support for Chinese is patchy. Turnitin's AI-writing detector won't process it, because coverage is limited to long-form English, Spanish, Japanese and Modern Arabic [1]. Turnitin does list Simplified and Traditional Chinese for Translated Matching, but that feature translates a paper into English to find matching sources and doesn't measure AI writing [2]. Originality.ai includes both Chinese scripts among its 31 languages [3]. Copyleaks names Chinese (Simplified and Traditional) among the languages it says it supports, though the accuracy figures on its page cover only English, French, German, Italian, Portuguese and Spanish [4]. GPTZero leaves Chinese off its fully supported list [5].

If your mainland university runs AIGC checks in CNKI's system, note what CNKI itself says: its user agreement for the service states that results are generated by an AI model, may include missed or false detections and are for reference only, and that the AIGC value is a probability with no bearing on a paper's quality [6]. In Taiwan, NTNU's guideline warns that detection tools have considerable accuracy limits and can't provide verifiable evidence, so teachers may not find a violation on a detector alone and should weigh oral questioning, writing-process records and version history [7].

Our own detector can't evaluate Chinese. It returned a score of 0 for both the AI-written draft shown above and its rewrite [8], which is why the sample carries no score. Keep your outlines, drafts and version history: they show how your thesis took shape.

Mandarin Chinese Linguistics

What Makes Mandarin Chinese Different

Script: Han logographicFamily: Sino-Tibetan (Sinitic)

Where AI-written Mandarin Chinese slips

•Measure words (liangci) mismatched to their nouns
•Aspect particles le/zhe/guo used mechanically
•The three 'de' (de/de/di) distinctions confused
•Connector overuse and 'and/but' translationese calques

What native Mandarin Chinese writers do

Sentence-final particles a/ba/ne/ma
Chengyu four-character idioms placed naturally
Topic-comment structure and dropped subjects

Writing notes

Match the character set to your readers. Mainland China's standard for general use is the State Council's 2013 Table of General Standard Chinese Characters (通用规范汉字表), while Taiwan writes traditional characters, and conversion is not one-to-one: simplified 发 covers both 發 (to issue) and 髮 (hair). Our sample above is in simplified characters and we haven't yet run traditional text, so proofread any traditional-character result by hand.
Keep full-width Chinese punctuation, such as the enumeration comma 、 and the title marks 《》, and replace any half-width Western commas or periods that slip in during rewriting or translation. For a Taiwanese school, note that the Ministry of Education's punctuation handbook puts 「」 first, with 『』 for a quotation inside a quotation.
Length requirements for Chinese theses can be set in characters (字) rather than words; Huaqiao University's School of Physical Education, for example, asks for bachelor's theses of about 8,000 to 10,000 characters. Tool limits, SupWriter's included, are stated in words, so try a short passage first to see how much Chinese text fits in one request.
Compare the rewrite with your draft for meaning, not just flow. Check that the subject and audience haven't drifted, that connectives such as 例如 and 反而 still match your logic, and that every sentence is still grammatical. Expect some sentences to come back unchanged, as the conclusion did in the run above.

FAQ

Mandarin Chinese questions

Not with its AI-writing detector, which processes only long-form English, Spanish, Japanese and Modern Arabic. Turnitin's Translated Matching does accept Simplified and Traditional Chinese, but it converts your paper into English to look for matching sources rather than scoring AI use. Other vendors differ: Originality.ai and Copyleaks list Chinese, and GPTZero doesn't name it as fully supported.

Each school sets its own procedure, and we found no national threshold. In 2026, Shandong University of Technology's computer science school sent defence drafts above 40% to a warning list and capped their grade at “good”, while Huaqiao University's School of Physical Education has supervisors and the defence panel question students on passages its AIGC report rates high-risk. CNKI's own user agreement describes its AIGC results as for reference only and says they can include false detections.

We don't know, because we haven't measured it: we have not run SupWriter rewrites through CNKI's AIGC check, and our own detector returned 0 for both our AI-written Chinese draft and its rewrite. Check your school's AI rules first. Shandong University of Technology's computer science school, for example, bans using large AI models to directly generate a thesis's core content, such as the abstract, methods and conclusions. No tool can promise you a particular AIGC score.

The Degree Law lets a university withhold or revoke a degree when a thesis involves ghostwriting, plagiarism, fabrication or similar misconduct. The draft discussed in 2023 listed AI ghostwriting by name, but the final law leaves AI out, so your university's own rules decide how AI use is judged. Before any decision, Article 39 entitles you to hear the grounds and present your defence.

We found no single national rule; a 2023 Ministry of Education academic-ethics newsletter warned that using AI output in place of your own writing may raise ghostwriting (代寫) and plagiarism concerns, and said there was not yet a unified rule on labelling AI use. Universities now set their own policies: NTNU's 2026 guideline requires students to disclose the tool, version and how it was used, and bars submitting work produced wholly or mainly by AI. Under the Degree Conferral Act, a plagiarised or ghostwritten thesis means the degree is revoked.

You can paste traditional-character text with Mandarin Chinese selected; there's no separate traditional-Chinese setting. Our only test so far used simplified characters, so we can't show you a traditional-character result yet. Before you submit, check that every character and punctuation mark still follows the conventions your school expects.
