Compilatio AI Detector: definition and how it works
 

What is an AI Detector?

An AI Detector, or AI Checker, is a tool that analyzes a text to determine whether it was generated by an Large Language Model (LLM): GPT-5.2, GPT-5.1, GPT-5, GPT-4o, Claude Sonnet 4.5, Gemini 2.5 Flash, Gemini 3 Pro, etc.
The Compilatio AI Detector follows this principle but goes further. It is an AI detection tool powered by AI itself and trained to recognize writing patterns typical of AI generative systems.

 

How does the Compilatio AI Checker work?

The Compilatio AI Checker has been trained on a wide variety of texts, both AI-generated and human-written, to accurately identify content produced by artificial intelligence.
It is based on an advanced language model capable of understanding context, tone, and cultural nuances to detect AI in texts.
At the end of the analysis, the AI content detector provides a score indicating the percentage of text likely generated by AI and highlights the corresponding passages.

 

Detect AI

The 5 key steps of AI Detection

1
Text breakdown
Identify passages of homogeneous style in the text
2
Labelling passages
Determine the origin of the text for each passage: AI text or human
3
Grouping AI passages
Bringing together identified AI passages to create points of interest
4
Cleaning up results
Filter out irrelevant passages to reduce false positives
5
Presentation of results
Display the final result of the analysis in the report

Why detect AI-generated content?
 

You have the right to know where content comes from!

AI Detection makes it possible to verify the origin of a text and determine whether it was produced by a human or by an AI.
Using AI can sometimes conflict with ethical guidelines and may impact a learner’s academic journey or an individual’s professional reputation.

Compilatio software highlights suspicious passages. It is up to the user, whether a student, teacher, or professional, to analyze these indicators and take the appropriate actions.

How to interpret the AI detection score?
 

After a document is analyzed, the score provided by the AI Checker is a percentage between 0 and 100%.
It indicates the probability that a text was generated by AI. A low score suggests a mostly human-written content, whereas a high score indicates a a high probability that the text was generated by AI.
You can navigate through the suspicious passages to examine them in more detail.

In the AI Detection report, we refer to “passages potentially generated by AI” rather than “AI-generated texts,” because no AI Detector can claim 100% reliability.

The percentage of AI-generated content should always be interpreted with caution and complemented by human analysis.

What to do when AI content is detected?
 

It is important to take a step back and interpret the AI text score with caution. Ask yourself what is acceptable in your context.
 

Here are some good practices to follow:

  • If you are a student: Check the passages in question and clearly indicate your actual use of AI in your essay or student work (AI model used, type of use: research, rephrasing, translation).

  • If you are a teacher: Analyze the flagged passages, verify references and AI usage guidelines. Discuss with the student and, if necessary, conduct a supplementary assessment (for example, orally) to check their understanding.

  • If you are a professional: Review the passages detected as AI and assess potential risks related to this use.
