A reader’s companion

Reading,
in another language.

At dusk, the lighthousefaro on the cliff blinks, and the villagepueblo folds itself into the slow rhythm of the bay.

Al atardecer, el farolighthouse del acantilado parpadea, y el pueblovillage se entrega al lento ritmo de la bahía.

Free, and no account needed. Or read a passage in the reading room first, with nothing to install.

A line copied by hand, a page in El País, a song on YouTube. The extension, recorded live.

What it does

yunit picks a few words you might not know on every page you read and pencils a small translation above each one, the way a reader notes a marginmargen. The sentence stays intact, the line below stays open, and reading remains the priority.

Select any word or phrase to translate it where you are, and click a word to keep it.

On YouTube, songs carry their lyrics translated line by line as they play. Premium adds live captions for videos that have no subtitles at all, two lines over the footage, the speaker’s language above and yours beneath, following in real time.

On keeping what mattered

Kept words return in later readinglectura, a little at a time, until they stay. Most days that means meeting them again on ordinary pages. Now and then one arrives as a small question mark, so you can check yourself, a few of these a day at most. For the words that stop appearing on their own, the lexicon holds a short review session built from the sentences you met them in.

The quiet parts

Your wordspalabras stay on your device. yunit does not track the pages you visit, and only the exact text you click or select ever reaches a translation service. Your lexicon exports to a single file whenever you ask. The privacy page is short and written to be read.
