Support
GemTranslate is a free, 100% on-device AI tool for iPhone with two parts. AI Translation translates text and even photos without the internet, and GemChat is a local assistant you can talk to with voice and up to nine images, with both Fast and Thinking modes. Everything runs on your device — private, offline and free, with no account and no ads.
Requirements
iPhone running iOS 18 or later. The app downloads its AI model on first launch (a few GB), so allow some free storage and a Wi-Fi connection the first time. After that it runs fully offline.
Frequently asked questions
Is my data private?
Yes. GemTranslate runs entirely on your device. We collect nothing and your content is never sent to a server.
Does it work offline?
Yes — after the one-time model download on first launch, the app works with no internet connection.
Do I need an account?
No. There is no sign-up and no account — just download and use it.
