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.

Free, project-first programming courses with an AI coding tutor
Lessons are anchored in engaging projects with genuine use cases, so what you build is useful rather than purely academic.
Move between topics freely and forge your own route through the material instead of being locked to one fixed order.
Paste or write code and the assistant looks through it, flags mistakes and suggests improvements with explanations and examples.
Ask the tutor to walk through a tricky problem in stages rather than simply revealing the final solution.
