Why Is My Essay Detected as AI? 5 Possible Reasons
Your essay can be detected as AI because it may have characteristics similar to machine-produced texts. It might happen even if your text is written manually but relies heavily on generic phrasing or overly complex sentence structures that resemble AI writing.
5 possible reasons why your essay is detected as AI are:
- Lack of variety in writing
- Absence of original thoughts
- AI-preferred vocabulary
- No sources cited
- Use of AI tools for proofreading
IvyPanda GPT Essay Checker,, like other AI detectors, is trained to spot the patterns typical to generated texts. If the tool reveals them, your piece will be marked as likely to be AI-made, even if you wrote it yourself. Here are possible reasons for that:
1. Your Essay Lacks Variety
AI text structures are monotonous and repetitive, with most sentences built on a subject-verb-object scheme. Another common trait of generated writing is a list of three elements—three related items or ideas used for clarity, balance, and completeness.
2. Your Paper Lacks Original Thoughts
As of 2025, artificial intelligence can’t create truly original ideas. Instead, it processes existing data and regenerates it. Thus, an essay written by ChatGPT will most probably retell known facts without adding any unique thoughts.
3. You’ve Used the Vocabulary Favored by AI
Pompous words and overused transitions are also something AI programs do a lot.
Here are some examples of phrases you will meet in every other generated text:
- In today’s world
- Consequently
- In addition
- Vivid tapestry
- Intricate landscapes
4. You’ve Forgotten to Cite Your Sources
Since ChatGPT doesn’t cite sources (unless instructed to do so), one might think its content is original. However, it inherently relies on pre-existing sources. Every idea produced by AI is derived from its training data, much of which comes from publicly available content or other datasets.
5. You’ve Used AI Tools for Proofreading
You may have written the text yourself and used automated tools to proofread it, but an AI detector marks it as generated. This happens because proofreading programs are also powered by advanced algorithms and, therefore, offer typical AI patterns.
Thank you for reading this post!
To avoid being accused of AI use, ensure your writing has a natural flow and incorporates various sentence structures. It is essential to employ versatile vocabulary and not abuse introductory phrases. Finally, always remember to cite the sources.
