Korean IME Fixer (한영타)

Everyone who types in both Korean and English has done it: you start typing without noticing the input mode is set to the wrong language, and a whole sentence comes out as gibberish. Type "안녕" while your keyboard is still in English and you get dkssud; type "hello" while it's in Korean and you get ㅗ디ㅣㅐ. The characters are wrong, but the keystrokes were right — each physical key you pressed maps to a specific letter in the other language. This tool reverses that mapping.

How to use it

1. Pick a direction:
   • EN → KO — you meant to type Korean but the keyboard was in English (dkssud → 안녕).
   • KO → EN — you meant to type English but the keyboard was in Korean (ㅗ디ㅣㅐ → hello).
2. Type or paste the garbled text. The corrected version appears instantly, and the copy button grabs it.

There's no "convert" button to press — the result updates on every keystroke, so you can paste a mangled paragraph and read the fix immediately.

How it actually works

The tool doesn't translate meaning; it remaps key positions. On a standard Korean keyboard, the Q key produces ㅂ, W produces ㅈ, A produces ㅁ, and so on. When you type Korean with the IME off, the computer records the Latin letters printed on those keys instead. The fixer takes each Latin letter, looks up which Hangul jamo sits on the same physical key, and — crucially — reassembles those jamo into full syllable blocks the way the IME would have: initial consonant, vowel, then any final consonant. Going the other way, it splits Korean syllables back into jamo and reads off the Latin letter on each key.

That reassembly step is why it can turn a flat run of consonants and vowels back into properly composed 한글, rather than leaving you a loose pile of jamo.

Gotchas worth knowing

• It assumes the standard two-set (두벌식) layout, which is what the overwhelming majority of Korean keyboards use. On a three-set (세벌식) layout the key positions differ, and the output won't line up.
• Characters that sit in the same place on both layouts — numbers, spaces, and most punctuation — pass through unchanged, which is exactly what you want in a mixed sentence.
• A few symbols that exist on only one layout may not have a clean counterpart, so odd punctuation can survive the trip un-converted. The letters, which are what matter, convert reliably.
• The conversion is purely mechanical, so it will happily "fix" text that was never garbled. If the output looks stranger than the input, you probably picked the wrong direction.

The remapping is a local character-lookup operation. Whatever you paste — a private message, or a password you fat-fingered in the wrong mode — never leaves your browser.
