Ukrainian is written in Cyrillic and it is not Russian, and the differences start at the alphabet: there are letters here that Russian does not have and sounds that Russian does not make. iLexiBox teaches the Ukrainian alphabet as its own thing, with a recorded Ukrainian voice on every card, rather than as a set of edits to somebody else's.
The Ukrainian on-ramp is written by hand, not generated, and it is 198 cards long. Every card is spoken in a recorded Ukrainian voice, and what you get right is scheduled for review rather than shown again at random.
Three of the pronunciation cards, exactly as the course teaches them:
Once you are reading, the level is the point. Make a text writes Ukrainian at the CEFR level, length, topic and format you ask for, so the step up is a setting rather than a new book. Speaking scores you word by word as you read aloud. Lexi talks back. The Translator fixes your mistakes as it translates and can give a simpler version at your level, and Writing marks what you wrote and says why.
Above the on-ramp sits the Course — a map of practice steps from A1 to C2 with grammar, vocabulary and a level test at the top of each level — and My words, where everything you save comes back on a spaced-repetition schedule in eight quiz styles.
The album is a photograph for every word, shelved by category, each caption written in Ukrainian and spoken in a real recorded voice rather than synthesised on the fly. It doubles as a game: see the picture, spell the word. Free to replay.
The first surprise is г, which is a breathy h from the throat and never the hard g of go — the hard g has its own separate and rare letter, ґ. Then и, a hard vowel made further back than an ee, and і and ї, which Russian does not have at all. Ukrainian spelling is also more faithful to the sound than Russian's: an unstressed vowel keeps its value rather than blurring, so what you read is much closer to what you say. Every letter is a card, and every word and sentence in the course is spoken in a Ukrainian voice.
