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.
One-click AI summaries of any webpage from your Chrome sidebar
Press the sidebar button on any page and ReadSmart returns a condensed summary of the page's text without you scrolling through everything.
Rather than dumping the whole page into a summary box, the extension detects the main textual content, which works best on news sites and long-form blogs.
Summaries you have already generated are kept, so you can return to a page you read earlier and jump straight back into the gist.
The extension lives in the Chrome sidebar, so generating a summary never pulls you out of your current tab or workflow.
