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.
Learn Git by walking through your codebase in a 3D voxel world
Renders any Git repository as a walkable voxel world, turning commits, branches, and the staging area into spatial objects you can explore.
A character-led tutorial teaches Git fundamentals progressively, starting from the very basics and building toward everyday workflows.
Try Git operations and see the outcome visualized before running anything against your real project, so mistakes stay harmless.
Inspect, navigate, and edit your code directly from inside the 3D environment without switching tools.
