Translate as you type in any app with Key Lingo - a smart, private iOS keyboard that supports 20+ languages, works offline, and keeps your data on your device. No switching apps, no copy-paste - just smooth, real-time translation wherever you write.






Hi all,
I built a custom iOS keyboard that translates text as I type, right inside any app (WhatsApp, Instagram, Notes, you name it). I created it because I kept having awkwardly slow chats in German with some old friends. I’m not fluent, so I'd constantly jump between the convo and Google Translate like I was speedrunning alt-tab. Now I just type in English, hit a button above the keyboard, and boom - German.
I know there are some other apps that do this, but they’re either kinda pricey or they send everything to the Google Translate API. I wasn’t thrilled about that. Key Lingo runs offline, keeps things private, and stores all dictionaries locally — no cloud snooping.
If you’ve ever fumbled through conversations in another language, maybe this’ll help you too. Would love any feedback, ideas, or brutally honest takes.
