About this app

TransferFriends is a fully offline AI translation app that lets you talk to anyone, anywhere, even without a network connection. Everything is processed on your device, so your conversations are never shared externally.

* Real-time voice conversation — Just press and speak. Both languages ​​are displayed in speech bubbles.

* Face-to-face mode — The screen is split vertically, and the other person's side is reversed. Ideal for conversations across a table.

* Text translation — Type and translate instantly. Natural-sounding translations.

* Image translation — Point your device at signs, menus, or documents to translate text in photos.

* Listen mode — Spoken words are converted into translated text.

* Fully offline operation
No communication is required for translation, speech recognition, summarization, or paraphrasing. Use it while traveling, on business trips, or in areas without network coverage. Conversations are processed on your device and are not uploaded.

* Strong multilingual and proper noun support
Supports Japanese, English, Chinese, Korean, Thai, Vietnamese, Spanish, Polish, and more. The proper noun dictionary accurately preserves names of people and places, and you can also register your own.

Convenient Features
Rephrase translations to be "more polite/more casual/shorter." Summarize conversations with a single tap.

Friends & Chat (Optional Feature)
Become friends with people you've met in person using QR codes. Messages are end-to-end encrypted between devices, and the operating server cannot read the content.
