The article is devoted to the controversial problem of the use of artificial intelligence in historical research. The introduction briefly examines the history of the emergence of "artificial intelligence" (AI) as a field in computer science, the evolution of this definition and views on the application of AI; analyzes the place of artificial intelligence methods at different stages of specific historical research. In the main part of the article, based on the analysis of historiographical sources and his own experience of participating in foreign projects, the author analyzes the practice of implementing handwritten text recognition projects using various information technologies and AI methods, in particular, describes and justifies the requirements for creating electronic copies of recognizable sources, the need to take into account the texture of information carriers, writing materials, techniques and technologies for creating the text; varieties and methods of creating paleographic, codicological, diplomatic datasets, historical and lexicological dictionaries, the possibility of using large language models, etc. As a methodological basis, the author used a systematic approach, historical-comparative, historical-chronological and descriptive methods, as well as the analysis of historiographical sources. In conclusion, it is concluded that the use of artificial intelligence technologies is promising not only as an auxiliary tool, but also as research methods that help in establishing the authorship of historical sources, clarifying their dating, detecting forgeries, etc., as well as in creating new types of scientific reference search systems for archives and libraries. At the same time, the use of artificial intelligence technologies is highly expensive and capital intensive, which is a serious obstacle to the widespread introduction of these technologies into the practice of historical research.
