AI text generators became popular among students and teachers.
These tools are actively used to create various text content. However, the author's work must remain independent. The author's knowledge and skills should not be questioned. To prevent the abuse of AI tools, we have created an AI content search module.
The advantages of our AI content search module are:
- A big list of the languages (the full list of languages can be obtained by contacting the support service),
- Verification speed,
- Check large documents,
- Probability percentage not only for the entire text, but for each fragment to identify the most affected part,
- Threshold value for the AI indicator, indicating the most affected parts,
- Five probability ranges with color codes, the darker the text, the higher the probability of AI,
- Dedicated AI content Report.
The AI content search module supports more than 100 languages. The accuracy of the search exceeds 94%. We detect text generated by ChatGPT, GPT-2, GPT-J, GPT-NEO, GPT-3, GPT-4, Gemini etc.

Grammatical and spelling errors often appear in student and even scientific papers. They are often ignored, however, errors related to grammar, spelling, style, punctuation, and so on are one of the main criteria for the quality of written work.
In addition, grammatical errors have become increasingly used by some students to bypass the anti-plagiarism system, for example, the author adds some kind of error to the entire text to break the order of words and prevent the search for similarities.
To save the teacher's time in searching for the above mentioned errors, as well as to prevent attempts at manipulation, we have created a module for searching for grammatical, spelling and other types of errors.
Advantages of the module:
- Supports more than 30 languages,
- Displays hints for corrections,
- Simple navigation through the text,
- Displays errors by category, where each category has its own color code.

System recognizes manipulations with text fragments in the form of:
- changing the order of words,
- adding or removing words,
- replacing words with synonyms,
- being translated,
As a result, the system will underline the “changed” fragments and highlight these fragments.
This function serves the purpose of clarifying whether a fragment was accurately paraphrased, or even if there was an attempt to bypass the system and intentionally hide the copied fragment.
Additionally, the system uses the SmartMarks feature to identify subtle alterations in text, such as changing word sequences, adding or omitting terms, and using synonyms to rephrase content. These alterations are displayed with lighter shading to indicate potential paraphrasing manipulations.
When hovering over highlighted text, a comparison with the original source is shown, making it easier to assess whether the changes are intentional attempts to obscure copied material.
This functionality is particularly useful for identifying fragments that maintain conceptual similarity while avoiding direct duplication, ensuring a thorough evaluation of document originality.

The translation plagiarism search algorithm allows you to find similarities in the translated text. The system supports more than 100 languages, including English, Spanish, German, French, Arabic and even Chinese. Having loaded the work into the systems, you can choose the combination you need, after which the system will show which fragments were found as similar in the translated text.
To enable this feature, the user simply selects the desired language combination while uploading the document. The system translates the document’s content and compares it against databases, including the RefBooks database, partner institutions' databases, and internet resources. Fragments identified as similar in the translated text are highlighted, ensuring thorough and accurate verification.
The search of translated similarity module was created with the support of a machine learning algorithm, ensuring adaptive and precise analysis. The translated fragments and their original counterparts can be viewed side-by-side in the interactive similarity report for detailed assessment.

Our Domestic Search Module (DSM) can be installed on the server of the university, which allows you to search for similarities within your database. This is done in a simple way. Our system sends to the Module the text that your user has uploaded on his account in our system. The module searches for similarities and sends metadata back to the system for the fragment that was found in the university database. This metadata is reflected in your user's similarity report, the source is your database. The module can send us only the metadata that the university has entered into its database. This service became very popular due to GDPR and copyright restrictions.
Additionally, the DSM supports full integration with the University's existing IT infrastructure, ensuring seamless compatibility and quick deployment. The system uses advanced algorithms to identify similar fragments, and the results are presented in a detailed similarity report. The report highlights the exact locations of matching text and provides direct links to the original sources within the university's database. This enables evaluators to analyze content efficiently while maintaining the integrity and security of institutional data. Moreover, DSM can be configured to automatically update the database by indexing new documents, ensuring the system remains up-to-date with minimal manual intervention.
