No internet needed — just talk, and be understood. A privacy-first, fully on-device offline translator and interpreter.
Voice translation, conversation, real-time captions and text translation — speech and text are recognized, translated and read aloud entirely on your device. Nothing is sent to the cloud, so it works on a plane, abroad, or with no signal.
Great for personal use such as travel and study, and for business too: store counters, reception desks, and customer service. One device for multilingual interpreting and inbound customer support.
* Each language's translation and voice models download once. After that, everything works offline.
■ Why Offline Translator
- No connection required: works even in airplane mode or with no signal.
- Privacy-first: no account, no cloud. Your speech and text are never sent to a server for translation.
- Real-time: as you speak, your words are translated and captioned into the other language.
- Multilingual: many languages, starting with English and Japanese.
■ Four translation modes
【Conversation — two-way voice, face to face】
The screen splits in two so people across a table can talk naturally — you speak and it translates into their language, they speak and it translates back, in real time, with optional read-aloud. Ideal for travel or serving international customers.
【Live captions】
Recognizes speech on the spot and shows the source and translation together — great for meetings, seminars, or checking what you heard.
【Text translation】
Translate typed or pasted text. Tap once to read the result aloud or copy it — for emails, signs, menus and drafts.
【Read aloud】
Reads translations in a natural voice at an adjustable speed — to check pronunciation or let the other person hear it.
■ Where it shines
- Stores, reception & customer service (commercial use OK): checkout counters, hotel front desks, restaurants, clinics and government windows — for international customers and inbound visitors.
- Travel & business trips: airports, hotels, restaurants, taxis, shopping.
- Learning: English conversation, listening and pronunciation practice.
- Privacy-sensitive moments: translate confidential text without sending it out.
