How korean-assist works

korean-assist turns Korean you actually want to read into typing practice. Every word you type is one you read, spell, hear and (if you like) look up, so you learn vocabulary in context while building real Korean keyboard skills.

  1. The text screen with saved texts on the left and a Korean passage in the editor

    1Bring your own Korean

    Paste anything: a textbook dialogue, a news article, song lyrics you’re learning, your own diary. Or import a YouTube video’s captions (see “Want to import a YouTube video?”). Save texts to your library and pick up where you left off.

  2. The typing screen: finished words in white, the current syllable underlined while it’s being typed

    2Type it, word by word

    Finished words turn white, mistakes turn red, and a syllable you’re still building shows the jamo typed so far, underlined (ㅎ → 하 → 한). Press space for the next word; backspace on an empty word goes back to fix a mistake.

    • You need a Korean keyboard turned on. On a Mac: System Settings → Keyboard → Input Sources → add “2-Set Korean”. On Windows: Settings → Time & language → Language → add Korean.
  3. 3Hear every word

    Each word is read aloud as you finish it, linking how it sounds to how it’s spelled. For texts imported from YouTube, the video itself plays the part you just typed, so you hear the real speaker. You can choose how much plays in settings, and ctrl+s says it again.

  4. 4Look up any word instantly

    Press ctrl+d after a word you don’t know. A banner shows its dictionary form, what it means in this sentence, and how it breaks down into the word and its particles or endings, without interrupting your typing. Meanings are shown in your language.

  5. 5Ask 선생님 when you’re stuck

    선생님 is the Korean tutor behind the round button in the corner of every screen, and already knows what you’re typing: the sentence, the word under the caret and the words you just got wrong, so you can simply ask “why was that wrong?” or “what does this ending do?”. It’s free with an account, up to a daily number of messages, and premium gives you more.

  6. The results screen with words per minute, keystrokes per minute, accuracy and missed words

    6See your progress

    Finish a text to see your speed (wpm and 타수, the usual Korean keystrokes-per-minute), your accuracy, and the words you missed. Click a missed word to look it up. Long texts remember your place, so you can practice a few minutes a day.

Why typing helps you learn

  • You can’t skim. Typing makes you notice every syllable, particle and ending you might read past.
  • Sound, spelling and meaning together. Seeing, typing and hearing a word at the same moment helps it stick.
  • Vocabulary in context. Words come from real sentences you chose, and look-ups explain them as used there.
  • A real skill on the side. You build Korean keyboard fluency you’ll use for chatting, searching and writing.

Everything you practice with here is free. Premium gives you more of the extras. see pricing

Import a YouTube video

Any Korean YouTube video with captions can become typing practice. A bookmark grabs the captions right from YouTube in your browser, and korean-assist plays the video along as you type.

  1. 1Add the bookmark (once)

    Drag this button to your bookmarks bar: → korean-assist

    • No bookmarks bar? Press ⌘+shift+b (Chrome, Edge, Safari), or in Firefox right-click the toolbar → “Bookmarks Toolbar”.
    • Firefox and Safari: you can also right-click the button → “Bookmark Link…” / “Add Link to Bookmarks”.
    • Any browser: then add a new bookmark named “→ korean-assist” and paste the code as its address.
  2. 2Open a Korean video on YouTube

    Any video with Korean captions works: human-made subtitles or YouTube’s auto-generated ones. Look for the CC button on the player.

  3. 3Click the bookmark

    A small note appears on YouTube while it grabs the captions, then “sent to korean-assist ✓”. Your video keeps playing (or stays paused) just as it was.

  4. korean-assist with the imported transcript in the editor and the linked video shown above it

    4The transcript lands in korean-assist

    A new tab opens with the captions in the editor and the video linked. Trim or edit the text if you like, then save it to your library or start right away.

  5. Typing along with the video playing above the words

    5Type along with the video

    As you finish each word (or sentence, see settings), the video plays that part so you hear the real speaker. ctrl+s replays what you just typed, ctrl+p plays what’s next, and ctrl+m switches to the synthetic voice.

Works in desktop Chrome, Edge, Firefox and Safari. If you ever get a message that your bookmark is out of date, drag the new one from step 1 to replace it.
