By 2026, screening for signs of artificial intelligence use had become an important part of academic integrity and the preparation of research papers for submission. At the same time, AI detectors do not provide a definitive conclusion about the authorship of a text, so their results must be evaluated in conjunction with editorial and content analysis.
