Helgio Highlighter

Translate words and phrases in context while reading websites, documents, and YouTube subtitles.

Click any word or phrase — on a website, in a document, or in YouTube subtitles. Helgio shows the translation in the context of the full sentence, not just a dictionary definition. The word is saved to your vocabulary automatically. WHERE IT WORKS Websites — Read news, articles, blogs, forums, and work pages in any language. Click any word to understand it in context. YouTube — Click any word in the subtitles while watching a video. The translation appears instantly — no need to pause. Documents — Upload a PDF, Word, PowerPoint, Excel, or EPUB file and read it like a regular webpage. Click any word — it works the same way. Books — Read books in the original. Every unfamiliar word is one click away. YOUR VOCABULARY Every word you click is saved automatically with its meaning and the original sentence for context. Practice later with flashcards built from real content — not random word lists. WHY HELGIO IS DIFFERENT A regular translator gives you a one-time translation. Helgio builds a learning loop: real content → contextual understanding → saved word → flashcard → practice. When you look up a word, Helgio explains what it means in that specific sentence — not just a list of possible meanings. HOW TO START 1. Install Helgio — one click, no registration. 2.
