LangSwitch

Detect mistyped keyboard layout and suggest local conversion.

Typed in the wrong keyboard layout? LangSwitch fixes it as you type. Type "dkssud" and get 안녕. Type "ㅗ디ㅣㅐ" and get hello. • Korean: English keys become Hangul (Dubeolsik), and Hangul typed by mistake becomes English • Chinese: pinyin becomes characters (nihao → 你好) • Japanese: romaji becomes kana and kanji (arigatou → ありがとう) Smart, not pushy LangSwitch reads the words around each one, so English stays English and Korean stays Korean. Words that could be either ("so" or 내) follow the sentence they're in. Easy to undo Press Backspace right after a conversion to get your original text back. Undo the same word twice and LangSwitch stops converting it. Make it yours • Three sensitivity levels: Strict, Balanced, Eager • Turn it on or off per site • 10 tooltip themes, including Liquid Glass, with Light, Dark, or Auto • Chinese and Japanese punctuation, kana-only mode, and more Private by design Everything runs on your device. Nothing you type ever leaves your browser, and password fields are never touched.
