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.

The extension watches pages as they load and decodes any QR code that appears, so you rarely need to press a scan button.
You can also decode a QR code on demand straight from the extension's popup menu when auto-detection is not convenient.
Turn a page link or selected text into a QR code and download the resulting image for sharing or printing.
The developer states the extension does not transmit or store user information, and the Chrome Web Store privacy label confirms no data collection.
