All quests
Practice the quests other learners are using.
Photo quests PRO
Turn a photo of a menu, a document, or a webpage into a quest.
Challenge yourself
Each level you pass adds harder words and sentences on the same topic, until you know it thoroughly. Track your performance on every word and sentence: We record how you do in every case and tense, when speaking, reading, writing, or listening, and we give you new exercises based on how well you're doing.
Grammar
All seven cases
Practice all seven Czech cases with fill-in-the-blank drills, sentence completion, translation, and finally roleplaying. You'll translate by both writing and speaking the correct form, as well as during the roleplay in the level tests.
Verb tenses
Work on verb tenses via translation with fill-in-the-blank drills, sentence completion, translation, and finally roleplaying. You'll translate by both writing and speaking the correct form, as well as during the roleplay in the level tests.
Detailed statistics PRO
Your performance on every word is tracked for each case and tense, in speaking, listening, reading, and writing. You can check your overall performance anytime for a specific case, tense, or skill, and practice each category specifically.
Word order
Rebuild real Czech sentences word by word.
Plurals and adjectives
Noun and adjective endings in context, with fill-in-the-blank sentences.
Advancing difficulty
You'll see new forms and grammar challenges as you get better. Because we score words individually, you'll only see forms you're ready for, no matter how new a word is for you.
Speaking
Read-aloud questions PRO
Say words and sentences and get checked by speech recognition.
Detailed pronunciation measurement PRO
Check your pronunciation at the letter detail. Speaking exercises are graded on individual sounds, rhythm, and pitch, and on awkward pauses for roleplaying exercises. Get a combined "understandability score" during roleplay.
Pronunciation stats PRO
See which sounds you struggle with the most, and focus specifically on speaking, without using a quest. Our practice sessions automatically target areas that are challenging for you.
AI roleplay
Quest roleplays PRO
Each quest includes 5 roleplaying scenarios, where you'll practice improvising and speaking about the topic.
