The paper discusses the possibilities of digitalization of criminal procedure and its importance for optimizing prosecutorial supervision, including high-tech supervision. The development of digital technologies urgently requires not only legal changes, but also the rational use of artificial intelligence in criminal proceedings. Purpose: to determine the limits of the use of artificial intelligence in criminal proceedings and, in particular, prosecutorial supervision. Methods: the author uses empirical methods of comparison and description; theoretical methods of formal and dialectical logic. A special scientific legal-technical method is also applied. Results: The prosecutor’s access to the materials of the criminal case will make it possible to ensure the continuity of prosecutorial supervision and will enhance its efficiency. The use of software will be a factor preventing the gathering of evidence in violation of the Code of Criminal Procedure of the Russian Federation. It is proposed to use special methods of supporting public prosecution in specific types of criminal cases in the development of an artificial intelligence program.  Digital technologies can be used to analyze crimes, its causes and conditions, and to develop effective means of preventing it when the prosecutor exercises the function of coordinating the activities of law enforcement agencies in combating crime.
