Welcome to Putnik
Putnik helps you communicate while traveling abroad. It uses AI to translate between 21 languages and works completely offline, no internet required.
Get it on Google Play
Offline translator · On-device privacy · One-time model download
Built for real trips
Everything runs on your phone after setup—no accounts, no servers reading your chats.
Works offline
After a one-time download, translate with no internet connection. Built for airports, roaming, and spotty Wi‑Fi.
21 languages
Carry natural conversations across major world languages—powered by on-device AI (NLLB-200), not cloud APIs.
Speak or type
Use your voice with on-device speech recognition, or switch to typing whenever you prefer.
Pass-the-phone chats
Two-sided conversations: you and your partner each have a side of the screen—perfect for travel and quick exchanges.
One-time setup
Putnik works fully offline, without an internet connection. First, the app downloads AI models for translation and speech. These downloads are large (on the order of ~2 GB total) but you only do this once—we recommend Wi‑Fi.
