The Single Anti-Plagiarism System (JSA) is the only anti-plagiarism system on the market which has full access to ORPPD, the constantly updated database of written diploma theses, and the data entered together with the academic work are supported by the POL-on system. The system also uses NEKST, the complete Polish Internet database, rather than a search engine.
The JSA is free of charge and shared by all universities in Poland, thus guaranteeing uniform verification methods applied to a homogeneous set of reference data. One of the advantages of the JSA is that it provides all degree-granting institutions with the same anti-plagiarism verification standards.
The use of the system ensures standardisation of anti-plagiarism checks with regard to the same reference databases and according to the same algorithms, which also ensures equal treatment for all students.
Under the previous system, academic theses were checked against the database of their home university and against the database compiled for of universities that signed a relevant agreement to exchange their databases. At present, each written diploma thesis is checked against the academic theses stored in the Polish National Repository of Written Diploma Theses (ORPPD). The repository currently contains over 2.7 million theses from all Polish universities.

Text analysis
JSA-based text analysis returns the following results:
- Special characters or those outside the language of the thesis – the system highlights characters which are considered as special characters and those that are not part of the relevant alphabet.
- Non-recognised words – the system will recognise and highlight words outside the thesis language; however, the results will not raise suspicion if the work contains words from foreign languages.
- Passages written in a different style – the system uses stylometry and returns information about the number of passages that represent a different writing style.
- Length of words in the thesis – a slider can be used to specify the length range of highlighted words found in the thesis. The limit “≥ 20” indicates words containing 20 or more characters.
