The Celtic languages are living languages. But the tools available to learners have never matched the languages themselves. Generic apps translate Spanish-course templates. Grammar books explain rules you can't apply. blas. is built from scratch for the six living Celtic languages. Séimhiú, urú, treigladau, kemmadurioù. We are the only app that drills consonant mutations systematically, alongside conjugation, declension, reading, listening, conversation, and daily word games built around how Celtic grammar actually works. No mascots. No confetti. No streak guilt. Clean design, precise feedback, progress you can measure. SIX CELTIC LANGUAGES Gaeilge (Irish), Cymraeg (Welsh), Gàidhlig (Scottish Gaelic), Brezhoneg (Breton), Kernewek (Cornish), Gaelg (Manx).
