About this extension
Welsh Sensim slowly weaves the Welsh language into the webpages you already read every day. News articles, forums, social media, AI chats, blogs — ordinary English words begin transforming into readable Welsh phonetic equivalents as you browse naturally across the internet. No lessons to complete. No flashcards. No separate app demanding your attention. The language simply becomes part of your daily world.

Every midnight, three new Welsh words unlock. Each word replaces all related English meanings simultaneously, allowing patterns and recognition to emerge naturally over time. Miss one day and your progress stays intact. Drift away longer, and a few words fade back — like language itself, kept alive through continued presence and memory.

Welsh Sensim uses North Welsh Gwynedd pronunciation, the living voice of Snowdonia, the Llŷn Peninsula, chapel hymns, mountain valleys, bardic poetry, and the enduring spirit of Cymraeg. The phonetics are written for English speakers, making the sounds approachable from the very beginning.

Built for the Welsh diaspora, heritage learners, curious minds, and anyone who carries hiraeth for a language older than kingdoms, Welsh Sensim is not about studying Welsh. It is about living beside it, gradually, until it begins to feel familiar.

Cymraeg am byth.
