LEO Dictionary is an online bilingual dictionary service with 12 language pairs, including English–German, English–Spanish, and French–German. Search works in either direction, with autocomplete, spelling-tolerant suggestions, and a text search that lets users select words for lookup. Dictionary entries can bring together definitions, grammar, etymology, noun and verb tables, audio pronunciation, links to monolingual dictionaries, and related forum discussions. Users can also ask the LEO community about terms that are missing from the dictionaries. The free vocabulary trainer lets learners create and grow personal word lists, quiz themselves, and follow progress through statistics. LEO lists language courses for its dictionary pairs; some lessons are available to try free, while course access is purchased separately from LEO Pur. The English–German trainer includes vocabulary collections for Westermann’s Camden Town books and uses LEO-developed AI to suggest words for review. LEO’s free smartphone app provides the twelve pairs and trainer. Firefox and Chrome extensions offer selected-word lookup from a browser context menu, and LION provides dictionary access from Windows applications. LEO GmbH, based in Sauerlach, Germany, says its servers are in Germany and stored data are not sold or forwarded to third parties. Its policy says IP addresses are kept for up to seven days before deletion or anonymisation.
