Yunit – companion language layer por yunit

yunit is a small, attentive companion for foreign-language reading. It picks a handful of words on every page you visit and translates them inline, just above the word, so vocabulary travels with you across the web.

What you get out of the box

• Inline word annotations on any page, density adjustable
• A per-word panel with translation, sentence context, definition, and pronunciation
• Selection translation for full sentences and phrases
• Dual-language reading mode (Alt+Shift+D) for side-by-side comprehension
• Synced lyrics view on YouTube, each line glossed inline
• A vocabulary panel with spaced-repetition review timing and a confidence score per word
• Per-site rules: pause yunit anywhere, or run it only on chosen sites

yunit is local-first by default. The picker, your vocabulary, and your settings live on your device. Anonymous use never touches our servers.
