1. Students: how to check if your essay is written by AI?

Can AI be detected in essays?

Using AI or not, it's important to verify whether your assignment might appear AI-generated before you turn it in. AI checkers for students, like Compilatio Studium, analyze your writing and help you determine if your essay could be mistaken for being written by a generative AI like ChatGPT or Gemini.

a. Why is it important to check if your text is generated by AI?

With the rise of AI, many teachers now use plagiarism detection and AI content detection tools to review their students’ assignments.

The goal is to make sure your essays reflect:

Your understanding of the topic
Your critical thinking skills
Your personal reasoning
Your ability to structure, argue, and defend your ideas
The skills you’ve actually learned

However, when you rely too much on generative AI tools like ChatGPT, Gemini or Claude, your writing can become uniform and lack depth, making it harder for teachers to evaluate your real work.

That’s why it’s smart to check if your essay is written by AI before you turn it in. Doing so helps you:

Avoid misunderstandings about your work
Strengthen the credibility of your arguments
Identify areas that need more detail
Improve the overall quality of your essay

Note: Using AI tools isn’t always forbidden, but it’s often regulated by your school. Always review your institution’s AI usage policy or guidelines. For example, the University of Oxford has a clear framework for a responsible use of AI.

b. Why might your work be flagged as AI-generated?

Sometimes, an assignment you wrote entirely on your own can be flagged as “probably generated by artificial intelligence.”
That’s frustrating, especially if you didn’t use any GenAI! This often comes down to how AI detectors work.

How do AI checkers work?

AI detectors, like Compilatio Studium, are trained using machine learning on large databases containing both human-written and AI-generated text. This training helps them recognize the distinct patterns and features of each type of writing.

They then assess factors such as perplexity (how predictable the text is) and burstiness (variation in sentence structure), to assign your essay an AI probability score.

check to see if something is written by ai

Here are some signs that can make a detector think your essay is written by AI:

A structure that’s too perfect, without natural digressions.
An impersonal writing style, neutral tone, and generic vocabulary.
Lack of personal input: no nuance, analysis, or clear position.
Frequent rewording or repetition without adding real value.
Vague or generic content without concrete examples or specific references.

These markers are used by AI Detectors to estimate a probability of text that may have been generated by a tool like ChatGPT, Gemini, Claude, etc.

How to interpret an AI detection score?

When you check if your essay is written by AI by an AI detector, you’ll get a percentage indicating how much of your work might match the style of GenAI.
It’s up to your school to decide what’s considered a “high” AI usage score, so check with your teachers or your institution’s AI policy.

No AI checker for essays is 100% accurate!

For example:

Your natural writing style might be very uniform and trigger an AI flag.
A technical assignment might require a rigid structure that resembles AI output.

This score is only an indicator that your text shares similarities with AI-generated writing, not definitive proof.

That’s why using a student-focused AI essay checker like Compilatio Studium can be so helpful. You can check to see if something is written by AI before submitting, and revise any flagged parts to make sure your work reflects your own voice.

Generative AI tools are becoming essential companions for writing assignments. But before you start drafting, follow these tips to ensure responsible AI use:
