Kiten review
A focused, free desktop reference for Japanese words and kanji—not a full language course.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Kiten is KDE’s free, open-source desktop reference and study application for Japanese learners and readers. It combines English-to-Japanese and Japanese-to-English word lookup with a kanji dictionary, making it most useful to solo learners who want to check vocabulary or investigate characters while reading or studying. Linux and Windows builds make it available on those desktop platforms, but it is a reference tool rather than a guided language course.
Its standout strength is the range of ways to find and inspect kanji. Search by radical, grade, or stroke count, then browse readings, meanings, stroke counts, and stroke order. For word lookup, Kiten can filter rare or common and uncommon words, search for matches at the beginning, end, or anywhere in a term, and refine results by word type or within a previous result set. Query history supports revisiting earlier searches. Together, these tools suit readers who know what they want to look up and value detailed reference over a prescribed sequence of lessons.
Kiten is free and open source, with KDE documentation and community support. Its narrow desktop focus is also the main trade-off: it does not provide lessons, speech practice, a placement test, personalized review, or mobile apps. Learners seeking structured instruction, spoken practice, or study across devices should choose a course-oriented app instead. Pick Kiten as a companion dictionary for Japanese reading and character study, not as the center of a complete learning plan.
