An AI chemistry tutor that shows the working, not just the answer
Type the problem or snap a photo of it — a reaction to balance, a mechanism to explain, a titration calculation that will not come out right. Astra walks through it step by step and stays with you until the method sticks.

What Astra AI does for you
One subscription turns your own material into the lessons, practice and mock exams this page describes.
Every step shown and explained
Astra sets out the reasoning line by line — why a mole ratio is what it is, why an electron moves where it does — so the next problem feels easier.
Answers come last, not first · Follow-up questions welcome mid-problem · Explanations adapt to your level
Scan the question you are stuck on
Point your camera at a printed or handwritten question, including equations and structures, and get a worked walkthrough instead of a bare answer.
Turn your notes into practice
Drop in class notes, slides, worksheets or past papers. Astra builds questions from your own material, marks every answer and schedules the tricky ones for review.
Exam-ready by your date
Set your exam date and Astra turns the syllabus into a topic-by-topic plan with graded mock papers, then shows you exactly what still needs another pass.
One subscription, every subject
Chemistry comes with physics, biology, maths, history and the rest — plus flashcards, quizzes and podcasts — all under a single plan.
How to get started
Bring the problem
Type it, paste it or scan a photo from your worksheet or textbook. You never have to phrase it the way the textbook would.
Work through it together
Astra asks questions back, explains each step and checks that you can do the next one yourself before moving on.
Practise until it sticks
Similar questions, flashcards from your own notes and a graded mock exam close the loop before the real thing.
Frequently asked questions
Yes. Astra explains mechanisms, functional groups and reaction pathways step by step, works out why a reaction goes the way it does, and then checks you can apply the same reasoning to a new molecule.
Yes. Photograph the question — printed or handwritten, including equations and structures — and Astra reads it and walks you through the solution step by step.
No. Astra teaches the method: it explains each step, asks you questions along the way and only moves on once you have the reasoning, not just the result.
Inorganic, organic and physical chemistry across school and university syllabuses: balancing equations, stoichiometry, acids and bases, redox, equilibrium, kinetics, thermodynamics, organic mechanisms and lab calculations.
One Astra AI subscription covers chemistry and every other subject. Plans start at $9.99 per month, and annual billing costs about 17% less than paying monthly.
