Use Polytranslator when you need the highest translation quality— its Advanced tier is the most accurate translation engine on the market — or when your language isn't in Google Translate at all.

You want a fast, free translation of everyday text in a language it supports — Spanish, French, Chinese, Arabic, German — especially on mobile or offline. For that job it's the right tool.
Use Polytranslator when…
You need the highest-quality translation available — the Advanced tier is built for maximum accuracy on difficult, nuanced, or specialized text — or your language isn't in Google Translate at all — see the full 60+ language gap list (Ancient Greek, Old English, Navajo, Toki Pona, Moroccan Darija…) — or you need a dialect translated as itself, a whole document or photographed page translated with consistent terminology, transliteration, or the highest-fidelity output on a difficult text (the Advanced tier).
