Research shows that AI-based writing tools such as ChatGPT and Claude produce distinctive linguistic patterns. These patterns make it possible to detect AI-generated content and improve its quality.
Even after editing, AI-generated texts retain unique, recognizable markers. Refining these traces helps make the content feel more natural and human-like.
Studies have revealed that different AI systems generate text with identifiable stylistic and structural patterns. Here are some examples:
- ChatGPT
- Common phrases: Frequently uses expressions like “of course,” “for example,” and “generally.” Often begins responses with “Below…” or “Certainly!”
- Formatting: Structured text with emphasis, bullet points, and headings.
- Style: Detailed, context-rich answers with a formal and instructional tone.
- Gemini
- Phrases: “Here’s an example,” “provided below.”
- Formatting: Moderate use of headings and lists.
- Style: Balanced and practical explanations.
DeepSeek
- Phrases: “Key point,” “brief explanation here.”
- Formatting: Bullet points and emphasis on important aspects.
- Style: Analytical tone focused on core insights.

- Phrases: Frequently includes “let me,” “remember that,” or “find out if.” Also uses terms like “provided below,” “specific,” and “detailed” for clarification.
- Formatting: Heavy use of bulleted and numbered lists, with bolded highlights. Segmentation often includes transitions like “## Key Points.”
- Style: A mix of instructional guidance and explanatory detail, often leaning toward a narrative approach that clarifies how or why a task is performed.
One key finding from the research is that word choice is a major indicator of AI-generated writing:
“When we shuffled the words in AI responses, classification accuracy dropped only slightly. This suggests that many of the distinctive features are encoded at the word distribution level.”
If you’re using AI writing tools, here are practical steps to reduce these markers:
- Vary your introductions: AI-generated texts often start with predictable phrases. Rewriting the opening lines can help avoid formulaic patterns.
- Replace signature phrases: Identify and substitute expressions typical of specific AI models.
- Adjust formatting: Each model has its own formatting style. Altering layout and structure can make the text less recognizable.
- Restructure the content: AI tends to follow a predictable logic. Rearranging sections can create a more original flow.
- Add personal elements: Incorporate your own experiences, opinions, and industry insights—elements that AI cannot replicate.
While the study focuses on distinguishing between AI models, it also highlights the broader differences between machine-generated and human-authored texts.
As search engines become more adept at detecting AI content, formulaic writing may lose its value. The best strategy is to combine the efficiency of AI with human creativity and expertise to produce content that resonates with both readers and search algorithms.
