Upload a .docx and pick a direction: it translates it paragraph by paragraph with a model that downloads once and runs in your browser — the document never leaves your machine. The result is another .docx, ready to download.

Each paragraph inherits the formatting of its FIRST piece of text: a style change mid-sentence (a bold word inside an otherwise plain paragraph) isn't preserved. Word fields (page numbers, automatic dates, tables of contents) are left untouched, untranslated. Portuguese isn't available yet (there's no direct model with good enough quality).

These are machine translation models, not perfect ones: in German → Spanish, for instance, "Der Vertrag tritt … in Kraft" can come out as "El Tratado entrará en vigor…" ("the Treaty shall enter into force…", the typical EU-treaty wording, heavily present in the training data) instead of "El contrato entra en vigor…" ("the contract takes effect…"). Always review the result before using it, especially for a legal document.
