  Dictionaries can help language learners to learn vocabulary by providing
definitions of words. Since traditional dictionaries present word senses as
discrete items in predefined inventories, they fall short of flexibility, which
is required in providing specific meanings of words in particular contexts. In
this paper, we introduce the LitMind Dictionary
(https://dictionary.litmind.ink), an open-source online generative dictionary
that takes a word and context containing the word as input and automatically
generates a definition as output. Incorporating state-of-the-art definition
generation models, it supports not only Chinese and English, but also
Chinese-English cross-lingual queries. Moreover, it has a user-friendly
front-end design that can help users understand the query words quickly and
easily. All the code and data are available at
