Czech spelling is honest. Once you know what each letter and each accent does you can read a Czech word aloud correctly the first time you meet it, which is not true of English, French or Danish. iLexiBox front-loads that, along with the two facts about Czech rhythm that most courses leave a learner to discover late.
The Czech on-ramp is written by hand, not generated, and it is 485 cards long. Every card is spoken in a recorded Czech 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. The Text Generator writes Czech 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. The Conversation Partner talks back. The Translator explains a sentence instead of replacing it, and the Corrector marks what you wrote and says why.
Above the on-ramp sits the Path — a station map from A1 to C2 with grammar, vocabulary and checkpoint stations — and Words & Notes, where everything you save comes back on a spaced-repetition schedule in seven quiz styles.
The album is a photograph for every word, shelved by category, each caption written in Czech 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.
Those two facts fight each other. Stress is always on the first syllable, with no exceptions to learn — and an accent mark is LENGTH, not stress, so in malý the beat is on ma while the long vowel sits at the far end. Push the accented vowel louder, as an English speaker's instinct says to, and the word stops sounding Czech. On top of that, ě after d, t or n adds no vowel but softens the consonant, and ř, the sound Czech is famous for, is a rolled r and a ž at the same time. Each is a card with a recorded voice, because none can be learned from the page.
