blas.Duolingo dropped Welsh.
We picked it up.
900,000 people speak Welsh. Wales wants a million by 2050. blas. is the practice tool between your courses — built from the ground up for Welsh, not translated from Spanish.
Welsh language tools
Free, no account needed.
You've been here before.
Your nan slips into Welsh without thinking and you catch maybe half of it. You finished a beginner course, felt good — then stalled. The treigladau keep tripping you up. You need practice, not another lesson.
“I finished SaySomethinginWelsh but I still freeze in conversation. I need to practise, not learn more theory.”
The course that ends
“I know the treigladau rules. I still get them wrong in real time. Knowing a rule and applying it are different things entirely.”
Theory without practice
“Duolingo dropped Welsh. I was halfway through the tree. Now what? There's nothing else that drills grammar properly.”
Left stranded

A taste
This is what learning
Welsh feels like in blas.
This is a treigladau drill — one of dozens of drill types covering vocabulary, grammar, conjugation, reading, and more. Every answer feeds the spaced repetition engine, so you practise exactly what you need.
Get it wrong and it comes back sooner. Get it right and the gap widens. Your brain does the work — the algorithm just makes sure you practise the right things at the right time.
Apply the mutation
Why blas.
Built for Welsh.
Not translated from Spanish.
Made for Welsh from day one
Welsh has features that generic apps can't handle — mutations, verb-subject-object order, two dialect systems, gender agreement. blas. was designed around them.
Real spaced repetition
The FSRS algorithm tracks every word, rule, and grammar point independently. Weak spots get more reps. Strong areas fade to maintenance.
The practice between courses
blas. isn't replacing your Welsh course — it's the missing practice layer. Drill what you've learned until it sticks, then go back and learn more.
Works offline
Core drills work without internet. On the train, in Eryri, wherever. Your progress syncs when you reconnect.
