LingvoKit is an online resource for learning Lithuanian, centered on a comprehensive Lithuanian-Russian and Russian-Lithuanian dictionary. Its dictionary contains about 60,000 entries, with stress marks and accentuation patterns, and is regularly expanded by editors. Users can search in either language, enter words using basic Latin letters in place of Lithuanian characters, and look up as many as seven terms in one query.

If a word is missing, visitors can request a translation free of charge. The site also offers Lithuanian grammar materials, lessons, articles, a phrasebook, and reference categories covering topics such as verbs, family, animals, the body, colors, and professions. Additional services include Lithuanian-language courses and access to tutors.

Registered users can pay for expanded search, whole-text translation, and word-form analysis, with higher daily query limits. The dictionary is also available through a Telegram bot, and the site maintains social media channels and a related Latvian-Russian dictionary resource. LingvoKit presents tools and learning materials for students, teachers, and anyone seeking practical Lithuanian language support
