About Lanbla
Practice real-life phrases and words again and again, with help from AI. Pick from 13 study languages, including English, Korean, Chinese, and Spanish, and learn through flashcard-style repetition. The app can be shown in 6 languages. ■ Key features ・Flashcard practice Practice phrases and words as cards. Tap "Reveal answer" to see the answer along with key words worth remembering. Hear the pronunciation with the speech button, and save any card to Favorites with one tap. ・Sentences made for you with AI Generate Enter a keyword, and AI writes example sentences matched to your study language, level, and what you've told it about yourself, grouped into folders by date and keyword. ・AI Review finds your weak spots Words you start missing are collected automatically in the "AI Review" folder, and drop out once your accuracy recovers. ・Favorites folders and memos Save phrases and words to your own folders, practice any mix you like, and add a memo to each. ・Built to keep you going The home screen shows your streak and last 7 days of practice, plus a "Yesterday's MVPs" ranking of the previous day. ・Read-aloud and voice settings Phrases and words are read aloud in a natural voice. Set the speed and voice (male/female) for each study language. ・Make it yours (paid plans) Choose the app's main color. Tell the AI about yourself in AI Customize (why you're learning, situations you care about), and AI Generate will fit you even better. ■ Languages Study (13): English / Korean / Chinese / Spanish / Japanese / French / Italian / German / Esperanto / Tagalog / Russian / Portuguese / Vietnamese Display (6): Japanese / English / Chinese / Korean / Spanish / French ■ How to use 1.
