Umíme česky
Adaptive Czech drills — thousands of short exercises that adjust to your mistakes.
What it actually is
Built for Czech schoolchildren, this is a large bank of short adaptive exercises on spelling, case endings, verb forms and vocabulary, including games, dictations and multiplayer races, with a dedicated 'Czech as a second language' section for non-natives. The adaptive engine keeps feeding you what you get wrong, which is exactly what declension practice needs. It is entirely in Czech and pitched at native children, so the framing can feel odd; a lot is free, with personal and school licences unlocking the rest.
