The AI Humanizer: Analyzing the Mechanical Sense of GPT-5's Rewriting Instructions

After the popularity of AI writing tools, the review of AI content in universities and journals has become increasingly stringent. The 2025 global academic integrity research report shows that 67% of university teachers are aware of students' use of aigc tools to modify papers, but 42% of the cases have increased the repetition rate due to misuse. In the face of the encirclement and suppression of gptzero, origin.ai and Turnitin detection systems, how to effectively reduce the AI rate of papers has become the focus of many scholars' concern. This article will describe in detail how to significantly improve the AI detection rate with gpt-5 on the premise of ensuring the academic value of papers. Let's learn with the editor.

1 Why are papers written by AI recognized?

AI detection tools are mainly used to distinguish between people and articles written by AI according to the characteristics of the text. These characteristics include:

• Sentence repetition: Articles created by AI often have too fixed and repeated sentence structures.
• Vocabulary diversity: lack of diversified language expressions and personalized features commonly used by human authors.
• Regularity of the text: the text is very "perfect", lacking some minor flaws in people's writing.
• Transition naturalness: the cohesion between paragraphs may be too straightforward or patterned.

After understanding these inspection rules, we can use gpt-5 to make targeted improvements to make our text look more like human writing.

2 Gpt-5 core method of reducing AI rate

2.1 Diversification of sentence patterns

By adjusting the length and structure of sentences to break the regularity of AI generated text, gpt-5 can combine simple sentences into compound sentences, or split compound sentences into simple sentences. The flexible conversion of active voice and passive voice properly inserts transitional words and clauses to improve the fluency of the text Reference words:

• Make a change and reorganization of the following paragraphs in sentence patterns to prevent repetition of sentence patterns. It can be achieved by using simple sentences, compound sentences and complex sentences alternately, and adding some transitional words or naturally inserting some clauses.

2.2 Expression naturalization

Synonym replacement: replace high-frequency AI words with synonyms, such as replacing "however" with "however", changing "therefore" into "so", colloquial adjustment: add some phrases or connectives in human writing style, such as "actually" and "you know", or add a little parenthesis or filler, so that the text can read more like what people write, and the grammar is not perfect: deliberately make some sentences grammatically incorrect, such as staggering the subject predicate word order, and omitting some articles. Reference words:

• Replace the following text with general AI official words and repetitive words, use synonyms or different words to express the same meaning, add some mild humanized changes, such as slight academic colloquial expression (but not completely colloquial), and the grammar cannot be too perfect.

2.3 Inject personalized elements

Add some short reflective sentences, assumptions or transitional explanations in the appropriate place to imitate the ideas of human authors:

• From this point of view, we can deduce“
• "The interesting thing is to find..."
• "Connected with the above situation is..."

Reference words:

• Appropriately insert some reflective phrases, such as "I guess", or transitional phrases, such as "that is to say", to imitate the thinking process of human authors in writing.

2.4 Paragraph logic adjustment

Change the paragraph length and logical process to make the text more organic: divide or merge paragraphs appropriately, fine tune the internal logical order of paragraphs, and improve the naturalness of paragraph cohesion. Reference words:

• Adjust paragraph length and logical order appropriately to create an organic sense, and rearrange occasionally to increase readability without destroying logic.
