Linguee is a multilingual dictionary and translation-search service that helps users find word meanings and see how expressions are used in translations contributed by other people. Its search draws on a billion translations, offering examples that can help users understand context and choose suitable wording. The service includes English–Portuguese lookup and many other language combinations, including Portuguese with Spanish, French, German, Italian, Dutch, Polish and additional European languages.

Alongside the Linguee dictionary, the site promotes DeepL Translator for translating text and documents. Users can enter text for instant translation or upload files using a drag-and-drop option. DeepL also offers tools intended to support writing and provides mobile apps for translating on the go. The mobile service includes options to translate from images or documents and to use a device camera. Together, Linguee’s contextual dictionary and DeepL’s translation features support language learners and people working with multilingual text, from checking individual terms to translating longer documents.
