English ↔ Japanese translator
Translate between English and Japanese inside any app: chats, subtitles, games and photos.
How it works
Swift Translate translates between English and Japanese (日本語) inside any Android app — chats, subtitles, games, and photos — with a floating bubble. Both directions, no copy-paste, and it works offline with downloaded language packs.
- Install Swift Translate and turn the translator on.
- Drag the floating bubble over any Japanese (or English) text — the translation appears in place.
- To reply in a chat, type in your language first, then drag the bubble onto your text — the message is sent in Japanese (or English).
