A reader for the languages
the big apps forgot.
Laesi takes Icelandic, Finnish, the Sámi languages, Welsh, Faroese, Old Norse, and Latin as seriously as Spanish — with real morphological lemmatizers for 60+ languages. The ones the big apps never bothered with.
Mörðr hét maðr, er kallaðr var gígja. Hann var son Sighvats ins rauða.
Hann bjó á Velli á Rangárvöllum. Hann var ríkr höfðingi ok málafylgjumaðr mikill.

Built for the languages nobody else bothered with.
Laesi does Spanish and French perfectly well. But it's the only serious reader for sagas, for the Kalevala, for North Sámi, for an Old English charter. Start with the rare ones — the common ones come free.
The languages nobody else covers properly
Icelandic, Old Norse, Faroese, Sámi, Kven, Welsh, Irish, Kalaallisut, Latin. Not an afterthought. The reason Laesi exists.
Real lemmatizers, not surface-form lookup
Voikko for Finnish, spaCy across the modern European languages, GiellaLT for the Sámi family, Faroese, Irish, and Old Norse. CLTK for Latin and BÍN for Icelandic are on the roadmap.

Six kinds of readers.
The Nordic-phile
You're learning Icelandic or Faroese for the love of it — the sagas in the original, Scandinavian podcasts in your ears. You already live in Anki and Lute, and you want a reader that keeps up.
The classics student
You're reading Latin, Old English, or Middle English with a dozen tabs open — Whitaker's Words, Alpheios, Logeion, Perseus. You want all of it in one window, right next to the text.
The heritage learner
You're reclaiming the language of your family — Welsh, Irish, North Sámi, Kalaallisut, Southwestern Ojibwe. It's about culture and revitalization, and you want a tool that takes your language as seriously as you do.
The new arrival
You've moved to Helsinki, Reykjavík, or Tórshavn, and you need to read the real world around you — not B1 dialogues about ordering coffee.
The switcher
You've tried other reading apps and grown frustrated — the lag, the price creep, the UI getting worse every year. You want to own your tools and your data, and your existing knowledge levels import cleanly into Laesi.
The power user
You love the idea of LWT or Lute but wish someone would package it, add proper lemmatization, and stop making you tinker.
Common questions
Read what you actually want to read.
Sagas, eddas, Kalevala, Mabinogion, Beowulf, the Vulgate. You brought your own taste — we brought the tools.
