2026: Development of the chat bot "Prism"

Experts of St. Petersburg State University have developed a chat bot "Prism" for analyzing documents. With its help, users in the national MAX messenger can analyze texts for mentions of objects from various registers of the Ministry of Justice of the Russian Federation for free and quickly. You can download files up to 5 MB in electronic formats.txt,.docx,.pdf for verification, while the effectiveness and quality of analysis do not depend on the format. On average, it takes from a few seconds to a minute to analyze in a chatbot. The university announced this on February 13, 2026.

For February 2026, the chatbot is undergoing pilot testing. St. Petersburg State University pushed the user request in the IT market to develop specialists.

The work takes place in dialog mode, which helps a person to solve the task facing him without additional effort: there is no need to spend time mastering the interface, many have been using chat bots for a long time and have a good understanding of the mechanisms of their work. At the same time, corporate communications within universities are transferred to the national messenger MAX, - said Vladimir Starostenko, Vice-Rector for Digital Transformation and Information Security of St. Petersburg State University.

An important advantage of the bot is to ensure that the analysis is up to date, since the service automatically updates its database based on data from these registries. The full version of the Prism program, available by subscription, also allows you to configure the search for mentions based on individual user needs, for example, from other sources. Another advantage is speed, which makes the program especially attractive for large organizations and companies with large-scale document management.

Our development allows us to solve routine but high-resource tasks, for example, to audit documentation quickly and, importantly, efficiently. More recently, with the help of Prism, 200,000 documents (working programs of disciplines) consisting of about 3,000,000 pages were analyzed for one of the divisions of St. Petersburg State University. Just imagine how much time would be spent first on the search, and then on checking the identified mentions in manual mode. 'Prism 'managed it in two and a half days. That is, the program was analyzed at a speed of almost 1000 pages per minute, - said Vladimir Starostenko, Vice-Rector for Digital Transformation and Information Security of St. Petersburg State University.

The quality of working with different volumes of texts remains consistently high. The service analyzes both a one-page document and massive books or dissertations with equal efficiency. Thanks to this, the development of St. Petersburg State University specialists significantly saves users not only time to complete tasks, but also funds that would be spent on employee remuneration. In the future, the developers plan to expand the source base for which document analysis can be carried out.
