Your personal AI tutor for every subject, from notes to exam day.
Upload your notes, slides or past papers, set your exam date and target grade, and Astra assembles a topic-by-topic revision plan built around exactly what you'll be tested on.
Ask by typing, speaking or snapping a photo. The tutor explains concepts at your level, asks follow-up questions and keeps going until the idea actually clicks.
Generate guided lessons, flashcards, quizzes, true/false and smart-text exercises, plus an auto-generated podcast so every learning style is covered.
Practise with realistic oral and timed written mock exams that get graded, so you know where you stand before the real thing.
Put down roots in a new language
Words move through visible stages — seed, sprout, young, mature and radiant — so progress feels like a garden growing rather than a bar filling up.
Recognition, production and listening are scheduled separately, with sixteen drills including fill-the-gap, hear-and-pick and hear-the-difference.
A conversational tutor corrects what you actually wrote in your target language and hands you the missing words, which you plant with one tap.
Your decks, reviews, garden and stats live on your phone, with watering and the word map working without a connection and syncing later.
