The author discusses the key concepts of the artificial intelligence, computerized analysis and machine learning. The chatbots СhatGPT, GigaChat, Alisa can be used in the libraries and information centers to assist in translations of foreign publications, article reviewing, etc. The author examines the possibility of integrating chatbot into the websites to render the first assistance to the users, in particular beyond office hours. The author reviews using AI for literature system reviewing and argues that the selection process is more efficient, and time is saved. He demonstrates the AI capabilities to improve the relevance of response to the search queries in the library computerized systems and to develop user personal account services. The latter would enable to generate personalized recommendations for articles, patents and reviews within the subject scope of studies and to select the most relevant materials for publication. For the system proper operation, the author suggests to develop the system for evaluation of the produced materials and services quality. Based on this system and requested materials, the personalized analytical and recommendation system can be generated to identify the lines of further research and development. Despite underdeveloped technologies, impossibility of total replacement of the humans, high implementation costs, etc., the AI methods and algorithms of learning and analysis enable to computerize several information processing operations, to reveal patterns and trends, t o p redict u ser n eeds, w hich l ays t he w ay f or d eveloping a nd i mproving services in the libraries and information centers
