Polytranslator translates between 474 languages and writing styles. That includes every major modern language (English, Spanish, Chinese, Arabic, Hindi, French, Russian…) plus hundreds of languages no other major service supports: ancient and historical languages, indigenous American and Pacific languages, regional dialects, and constructed languages. See the full gap list on languages Google Translate doesn't support.
Ancient and historical languages
Ancient Greek and Koine Greek, Old English, Middle English, Old Norse, Gothic, Sahidic and Bohairic Coptic, Akkadian, Sumerian, Egyptian Hieroglyphs, Hittite, Old Persian, Aramaic, Syriac, Pali, Avestan, Biblical Hebrew, Old French, Middle High German — even reconstructed Proto-Indo-European. Translations aim for fidelity to the original text rather than smoothed paraphrase, which is why students, clergy, and researchers use them alongside dictionaries like the LSJ or Whitaker's Words.
Indigenous and small languages
Navajo, Hopi, Zuni, Cherokee, Apache, Muscogee, Sardinian, Okinawan, and many more — languages with few or no other online translation options.
Dialects treated as real languages
Moroccan Darija, Egyptian, Levantine, Iraqi and Gulf Arabic, Swiss German, Bavarian, Low German, Louisiana Creole, Neapolitan, Scots, and Wu, Hakka and Min Nan Chinese. Where Google Translate folds these into a parent language (or omits them), Polytranslator translates the dialect itself.
Constructed and fictional languages
Toki Pona, Sindarin, Quenya and Tengwar (Tolkien's Elvish), Klingon, High Valyrian, Dothraki — plus novelty styles like Shakespearean English, Morse code, and runes.
Documents, PDFs, and images
Upload a whole document (PDF, DOCX, PPTX, XLSX, EPUB) or a photographed page and get the full translation with consistent terminology — including for ancient-language sources like scanned manuscripts and scripture.
Pronunciation audio, dictionaries, and learning
A speaker button reads translations aloud — including approximate reconstructed pronunciation for ancient languages. There are built-in dictionaries, transliteration tools, free side-by-side Shakespeare translations, and free structured courses for Old English and Ancient Greek at Polyglot.
Built on peer-cited research
Polytranslator was built by the authors of the academic research it runs on. “From LLM to NMT: Advancing Low-Resource Machine Translation with Claude” (Enis & Hopkins, 2024) — cited over 125 times — showed how large language models achieve state-of-the-art translation for languages with scarce data; its first author, Maxim Enis, is Polytranslator's co-creator (with Andrew Megalaa), and that approach is exactly what powers the Advanced tier. The project's origin is “Ancient Voices, Modern Technology” (Enis & Megalaa, 2024) — written by the same team that runs this site — which built the first contextual machine translator for Coptic, the work that grew into Polytranslator.
