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.

Ask anything and get rich, interactive knowledge pages instead of link lists
Every query returns a finished, designed page rather than a list of links, formatted for the type of question asked.
Generates interactive courses, calculators, data explorers, visual timelines, quizzes, step-by-step guides and planners.
A rotating set of example queries lets users see the range of tasks the engine handles before typing their own question.
Users can tailor the look and structure of their results, or simply accept the generated page as-is.
