What Astra AI does for you
One subscription turns your own material into the lessons, practice and mock exams this page describes.
Stuck on a problem? Scan it
Point your camera at any question and get a worked walkthrough instead of a bare answer.
Explains the method, not only the result · Handles printed and handwritten questions · Follow-up questions welcome mid-problem
Explanations that adapt to you
Astra keeps measuring what you have understood, re-explains at the depth you need and moves faster through the topics you already know.
Every subject in one place
Maths, physics, chemistry, biology, history, economics, computer science, philosophy, psychology and languages, all under a single subscription.
The learning format that fits the moment
Turn any topic into flashcards, a quiz, smart text, a guided lesson or a podcast for when you would rather listen than read.
Evidence that you are improving
Weekly progress and mastery tracking show what has stuck and what still needs another pass before the exam.
How to get started
Add your material
Drop in your notes, slides, PDFs or a photo of the page you are working from, so answers stay tied to what you are actually being taught.
Ask your question
Type it, say it or scan it. You never have to phrase it the way a textbook would before you get help.
Work through it together
Astra walks you through the steps, checks your understanding along the way and sets practice until the idea holds.
Frequently asked questions
A search engine hands you a result and leaves you to work out whether it fits. An AI tutor works through the problem with you, explains the reasoning behind each step and asks questions back until you can do the next one yourself.
Astra covers every school and university subject in one subscription, including maths, physics, chemistry, biology, history, geography, economics, computer science, philosophy, psychology and languages such as German, Spanish and French.
Yes. Scan a printed or handwritten question and Astra walks you through the solution step by step, then stays with you for follow-up questions about the same problem.
No. Astra teaches the method, shows the reasoning and checks that you have understood it before moving on, so the same question is easier the next time you meet it.
It is built for catching up, keeping up and pushing for top grades. Astra skips what you have already mastered and spends your time on the topics that are still costing you marks.
Astra works on the web, so you can carry on a session from your phone, tablet or laptop.
It helps, because Astra builds its explanations and practice from your own notes, slides and past papers. You can also start with a question and add material as you go.
