About this extension
Breton Sensim gradually brings the Breton language into the websites you already read every day. News articles, social media, forums, AI chats, blogs, and everyday browsing slowly begin shifting as familiar English words are replaced with easy-to-read Breton phonetic equivalents. No lessons to complete. No flashcards to memorize. No separate app demanding your attention. The language simply begins appearing naturally inside the text you already live in.
Every midnight, 3 new Breton words unlock automatically. Each Breton word replaces all matching English meanings at once, allowing recognition and intuition to grow through repetition and immersion. Miss one day and nothing happens. Miss several days and a few words gently fade back, encouraging steady exposure without pressure or guilt.
The phonetics are written for English speakers so anyone can begin reading and speaking immediately. Across 1,000 days, you gradually absorb 3,000 Breton words rooted in one of Europe’s surviving Celtic languages.
Breton Sensim is inspired by the rugged Atlantic coast of Breizh — the stone villages, lighthouses, sea winds, folk songs, Celtic knots, and ancient traditions carried through generations of Brittany. It is designed for the Breton diaspora, heritage learners, Celtic language enthusiasts, and anyone drawn to the enduring cultures of the Atlantic world. Little by little, the language becomes part of daily life simply by being seen every day.
