Czech for the real world.
Not for games.
Tell us what you need to do in Czech. We’ll turn it into a lesson.
Focus on your situation.
How it works

One sentence about what you need to do. No generic exercises.

You start with the words for your situation, then learn their forms: cases, tenses and who is doing what.

Next you fill in the missing word of real sentences, and finally finish real dialogues one line at a time.

We show what you did well, what tripped you up, and the next quest that builds on it.
Czech cases? No problem.
We track your performance on every word individually, for cases and tenses, in speaking and writing. Our quests focus on your weak spots automatically, or you can choose to work on important skills individually: speaking, listening, reading, writing, cases, or verbs.

Check your pronunciation down to the letter.
We gently help you gain confidence speaking Czech, by analyzing your pronunciation on 3 levels: Syllable sounds, rhythm, and pitch. Read words, fill in grammar forms, repeat & translate full sentences, and roleplay whole conversations.

Every time you level up, test your skills with a roleplaying exercise. Each quest comes with 5 conversations. You'll speak with an AI and get an understandability score, based on pronunciation, awkward pauses, grammar and word use, in harder and harder situations.

Comprehensive coverage of every topic
Each quest has 5 levels, with vocabulary, grammar, sentences, and a roleplaying scenario. Questions get harder as you advance. By the time you complete the last level, you’ll have a broad vocabulary about your chosen topic, and you’ll be able to interact with Czech people in the real world.

We're teachers, expats, and enthusiasts who got tired of searching for good tools to learn Czech. No BS Czech is what we wish we'd had when we started.
