Your English, boosted.
In a language you already think in.
Every lesson is in English — but when something doesn't click, your AI specialist explains it in Czech, Slovak, Polish, Ukrainian, German or Spanish. Interactive practice, song and speech analysis, and a CEFR path from A1 to C2.
Learn
Bilingual block lessons
English content with native-language scaffolding at every step — grammar cards, vocabulary, dialogues, listening and discussion, 17 block types in all.
English in Music
Bring a song you actually like. AI breaks the lyrics down into vocabulary, grammar and idioms, then turns them into exercises.
AI Speech Guide
Read a passage, then answer out loud. You get a transcript plus scoring on pronunciation, fluency, grammar, vocabulary and content.
Practice that answers back
Nothing static, ever
Multiple choice you actually click, fill in the blanks, matching and drag-and-drop — with instant checking and explanations, not a printed answer key.
Flip cards and picture reveals
Vocabulary is extracted from each lesson into flip cards with definitions, IPA pronunciation and a translation in your language.
Written answers, real feedback
Your written responses are saved to your account, so your teacher can read them and reply with targeted feedback.
Your tutor, your language
Paní Liška, Frau Fuchs, Señora Zorra…
Pick the specialist who speaks your language. Switch any time — the whole platform's explanations, hints and translations follow your choice.
English-only when you're ready
Professor Fox is always there for English-only practice, free-form questions and immersion once you want to stop translating.
Help on every screen
Both tutors travel with you — in lessons, practice, songs and speech — so you never have to leave what you're doing to ask a question.
