Surface-form lookup · full lemmatizer planned

Welsh learners who want to read real material — not gamified streaks — are exactly who Laesi is for. Welsh is supported today with Wiktionary surface-form lookup. A morphological analyzer is being researched: unlike Irish or the Sámi languages, Welsh has no GiellaLT model, so we're evaluating other toolchains rather than promising a date.

Why Laesi for Welsh?

What the big apps miss

01

Reading-first, not streak-first

No owls, no XP. Import real Welsh text and study the vocabulary that actually appears in it.

02

Surface-form lookup today

Welsh works now with Wiktionary lookups. Mutation-aware lemmatization is being researched to improve hit rates on inflected and mutated forms.

03

A growing corpus

Welsh-language publishing, news, and Wikipedia give you plenty to read. Drop any of it into Laesi.

Features, for Welsh specifically

Every Laesi feature works for Welsh. The reader, the dictionary panel, the browser extension, and Anki export don't change from language to language — only the analyzer behind them does.
