Korean Initial Consonant (Chosung) Extractor

Pull just the first consonant from every Hangul character in a Korean sentence

Extracts the leading consonant — the chosung — from each Hangul syllable in Korean text. It's the standard way to build clues for Korean initial-consonant guessing games, and it's equally useful for generating search index keys for Hangul autocomplete.

FAQ

How are double consonants like ㄲ and ㄸ handled?
By default they're extracted as-is. If you turn on the "simplify double consonants" option, they're reduced to their single forms (ㄱ, ㄷ, and so on) instead.
Does it still extract initial consonants correctly from sentences mixed with numbers or English?
Yes — non-Korean characters like numbers, English letters, and symbols can either be kept as-is or removed, depending on your settings, so only the Korean portions of a mixed sentence are accurately converted into their initial consonants.
