About this extension
Spanish Sensim slowly blends the Spanish language into the webpages you already use every day. News sites, social media, forums, AI chats, blogs, videos, articles — familiar English words gradually begin transforming into readable Spanish phonetic equivalents as you browse naturally across the internet. No lessons to complete. No streak pressure. No separate app pulling you away from your life. The language simply starts appearing around you, little by little.
Every midnight, three new Spanish words unlock. Each word replaces all related English meanings at once, allowing patterns to emerge naturally through repetition and immersion. Miss one day and nothing happens. Miss several, and a few words gently fade back. The experience is designed to feel organic — more like living beside a language than formally studying it.
Spanish Sensim uses plain English phonetics so any English speaker can pronounce the words immediately. Over 1,000 days, the extension gradually unfolds a living vocabulary of 3,000 Spanish words drawn from one of the world’s richest linguistic traditions.
Built for heritage learners, diaspora communities, travellers, curious minds, and anyone drawn to the warmth and rhythm of the Spanish-speaking world, Spanish Sensim carries the spirit of Madrid cafés, Mexican plazas, Caribbean music, Argentine poetry, flamenco, salsa, Cervantes, García Márquez, and more than 500 million voices connected through one language.
Español siempre.
