1. The service
Korean, Corrected (korean-corrected.pages.dev) teaches the Korean people actually speak: everyday phrases, casual speech with friends, and slang and texting words. The quizzes and phrasebook are free and you can use them without an account. Signing in with Google saves your progress and opens the daily lesson.
2. Daily lessons
Signed-in learners get a new 5-question lesson each day for their level, free of charge. We may change or pause daily lessons at any time.
3. Learning content
Expressions reflect how people in Seoul talk today. Slang changes quickly, and some words are only for close friends; the notes say when. Some questions and the daily lessons are written with the help of AI. We check them, but mistakes can slip through. If you spot one, please tell us and we'll fix it. The site is a study aid and doesn't guarantee any exam result.
4. Your account and fair use
Please don't copy the lessons in bulk or try to break or overload the site. We may suspend accounts that do.
