Highlight a word on a page, in a document or in YouTube subtitles and get what it means in that sentence, saved as a card. An ordinary translator gives you a one-off answer and forgets it. Helgio remembers: the word is saved together with the sentence you met it in, and comes back as a flashcard later. Hacer la vista gorda does not mean "to make the fat view" — it means "to turn a blind eye". Helgio reads the whole phrase and shows what a word means in your sentence. Idioms and phrasal verbs stay in one piece. Translation runs on DeepL. Translates from English, German, French, Spanish, Italian and Portuguese. 20 translations without signing up, no card needed. For people who have outgrown textbooks: you watch series with subtitles and read articles without adaptation, but lose new words along the way. Your vocabulary grows out of what you actually read and watch, not someone else's list. WHERE IT WORKS Websites — news, articles, blogs, forums, work pages. YouTube — click a word in the subtitles while watching, no need to pause. Netflix — the same during a series. Documents — PDF, Word, PowerPoint and Excel open like an ordinary page. Books — read in the original, any unknown word is one click away. YOUR VOCABULARY Practise saved words in nine modes: puzzle, listening, word and full-phrase translation, writing and pronunciation. Reviews come back after 1, 3, 7, 14, 30 and 60 days. You can import Anki decks and dictionaries from CSV. HOW TO START 1. Install Helgio — one click, no sign-up. 2. Open a site, a document or a video and click a word. 3. Read the translation — the word is already saved. FREE TO START 20 translations without signing up, another 100 after you register. Saved words stay yours even without a subscription. INTERFACE LANGUAGES English, German, Spanish, French, Italian, Portuguese, Dutch, Polish, Turkish, Finnish, Hungarian, Greek, Ukrainian, Russian, Arabic, Chinese, Japanese. Install it and try it on the first article you open.
