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.
Turn notes, PDFs and slides into flashcards, quizzes, notes and mind maps
Screenshot a question inside Canvas, Blackboard, Moodle or any web page and get an inline answer with the reasoning laid out, without leaving the tab.
Generates decks automatically from your notes, slides or PDFs and schedules reviews so cards you keep missing resurface sooner; imports existing Anki and Quizlet decks.
Turns any material or topic into a practice quiz, grades each answer immediately and explains why it was right or wrong, then leans the next quiz into your weak spots.
Converts a topic or a long reading into an editable, interactive map of branches and relationships, useful for getting the shape of a subject before memorising details.
