About

Krend

Features
Read full description

Learn Korean by reading, not by drilling. Krend gives you short Korean articles graded from your very first word up to TOPIK level. Read at your own pace, tap any word you don't know, and keep it. The word becomes a Kard โ€” with its meaning, its part of speech, and the sentence you met it in. READ REAL KOREAN A new article every day, written for your level. Culture, daily life, society, food โ€” the Korean people actually use, not textbook sentences. TAP TO UNDERSTAND โ€” IN YOUR LANGUAGE Every word is tappable. One tap shows the meaning in your own language, plus the grammar behind the ending. 12 languages: English, Vietnamese, Indonesian, Thai, Tagalog, Mongolian, Nepali, Spanish, Portuguese, Russian, Chinese and Japanese. No dictionary, no leaving the page. LISTEN WHILE YOU READ Every article is an audiobook. Follow along sentence by sentence, adjust the speed, or close your eyes and listen. COLLECT WHAT YOU LEARN Words you tap become Kards. Your collection is a record of what you have actually met โ€” not a deck someone else made for you. CHECK YOURSELF Quiz your own collection with Krend AI, or take TOPIK PREP questions on the article you just read. GRAMMAR THAT MAKES SENSE Krammar walks you through Korean grammar one pattern at a time, with examples from the articles you have read. THE KOREAN NOBODY TEACHES Koinage explains the slang, the memes, and the phrases you will not find in a textbook. KEEP GOING Streaks, tiers, and weekly boards. Twelve rungs from Silver to Diamond, and 77 Master seats for those who make it. Krend Pro unlocks every article and removes the daily limits.
