This paper explores the potential of using cloud-based mind maps as a tool for learning foreign languages. It is concluded that their use is suitable for both language classes and students’ independent work. Criteria have been developed for evaluating cloud services in terms of their effectiveness in the educational process of creating mind maps. The paper characterises the conditions for accessing free versions of 16 cloud services for creating mind maps. Based on an experimental study, five cloud services are compared: Ayoa, Mindomo, Miro, Smartdraw, and Xmind. The paper demonstrates examples of using mind maps based on these cloud services’ templates for various types of language learning activities, including studying grammar topics, learning or repeating vocabulary, and writing essays. The paper identifies several advantages of using mind maps, such as visualising lexical material, structuring terminology by sector, enabling control and self-control in checking listening and reading comprehension, and serving as support for writing essays and composing oral stories.
