What's New in OnKey
1.5.3
August 10, 2026
OnKey is now a full keyboard. Type in 17 languages, then let AI polish it. • A real keyboard, built in: type everywhere you already type, without switching back and forth. • 17 languages: English, Spanish, French, German, Portuguese, Russian, Ukrainian, Turkish, Indonesian, Filipino, Czech, Danish, Korean, Urdu, Persian, Pashto, and Kurdish. • Korean done properly: Hangul letters combine into syllables as you type. • Right-to-left done properly: full layouts for Urdu, Persian, Pashto, and Kurdish. • Hold for accents: press and hold any key for accented letters and alternates. • Your languages, your order: choose the ones you use and hide the ones you don't. • AI stays one tap away: fix grammar, change tone, reply, summarize, and translate without leaving the keyboard. • Fixes: long rewrites replace your text cleanly, and VoiceOver now reads the whole keyboard. Type smarter, everywhere you write.
