This article is devoted to the problems of participation of the Prosecutor at the initial stage of criminal proceedings and the search for ways to optimize its activities in the light of the digital transformation of the Prosecutor’s office of the Russian Federation, carried out in three main areas, namely high-tech supervision, digital infrastructure, and the environment of trust. The transition to high-tech supervision and the development of digital infrastructure should lead to work with a single electronic case on the basis of a single interdepartmental digital online platform. At the same time, a single interdepartmental digital online platform will ensure interaction both within the prosecutor’s office and the interaction of the prosecutor’s office with the investigation, inquiry, public, and court bodies. The conclusion is drawn that the digital transformation of the Russian prosecutor’s office optimizes the activities of prosecutors at the initial stage of criminal proceedings, but this should be preceded by legislative changes aimed at strengthening the role of the prosecutor in pre-trial proceedings. It also states the need to increase the availability of information to citizens about the activities of prosecutors and the state of legality in pre-trial criminal proceedings and expand the list of statistical data posted on the official website of the General Prosecutor’s Office of the Russian Federation.
