Tap a manga line for Korean help: Langaku’s Korean edition

Published Oct 11, 2026

Developer Mantra announced the Korean launch of Langaku, a Japanese-learning app, on October 6. Users read Japanese manga in the original, tap a line for a Korean translation and vocabulary and grammar notes, and save expressions to a word list.

Key features

Available on iOS and Android, the Korean edition displays the original Japanese dialogue alongside an AI Korean translation when a line is tapped, with contextual vocabulary and grammar explanations and Japanese audio. Saved expressions in My List can be filtered by difficulty or manga title.

34 titles

The launch announcement lists 34 titles, including ONE PIECE and NARUTO, a different catalog from the English-learning service offered in Japan. The selection depends on Korean distribution rights, and titles and release schedules may change.

Pricing and AI explanations

Some content is free, and Langaku+ offers monthly and annual paid subscriptions; free-access limits and subscription terms are listed in the app. Mantra warns that AI explanations can contain inaccurate information.
