Learn the vocabulary from your lessons – the fun and systematic way. GET YOUR WORDS INTO THE APP IN NO TIME • With your own AI: copy the prompt, send a photo of the vocabulary page to ChatGPT, Claude or Gemini, paste the answer – free and without signing up in the app. • Scan a photo: the app reads the page itself, keeps the example sentences from the book and writes matching ones for the rest. For this you need your own Mistral AI key with paid access – a page costs just a few cents. • Topic instead of photo: enter a topic and the AI creates 30 matching words – from ordering at a restaurant to business English. SEVEN TYPES OF EXERCISES Flashcards, multiple choice, writing, fill in the blanks, advanced fill in the blanks, arranging words and speaking with pronunciation feedback – plus a duel against the computer. Every word comes with an example sentence, a translation and read-aloud. A STUDY PLAN THAT THINKS AHEAD The app schedules reviews using spaced repetition and reminds you every day which words are due. STAY MOTIVATED • Hearts, points and diamonds • 25 badges – some of them secret • Wish badges: parents decide what the reward is • Learning streak with a weekly overview and a daily goal FOR THE WHOLE FAMILY • Several profiles with their own avatars • Spanish, French, German, Italian, Dutch and Latin • Syncs between iPhone, iPad, Mac and Apple Watch via your own iCloud account • For iPhone and iPad in portrait and landscape, as a real Mac app – and on Apple Watch: flashcards and multiple choice on the go PRIVACY No ads, no tracking, no account with us. Your words stay on your devices and in your own iCloud account. Photos are only sent to Mistral AI if you set up a key yourself. AI can make mistakes – please check imported words.
