You canunderstandanything
Not just an answer to read. See how the idea works, take it apart piece by piece, and test yourself until it finally clicks.
Built from your course, not a textbook
Add your lecture PDFs, slides or photos of your notes. Lessons use your professor’s notation and examples, and every explanation points back to the page it came from, so you know it matches what you’ll be tested on.
What a lecture can’t show you
Built around how you study
A short course for every question, explained the way you like, ready when you come back.
Your question becomes a course. Each question turns into a course: its lessons in order, the pages of the one you're on, and how far you've got.
Read it your way. Take a lesson one box at a time or as a single page, and ask about any part of it.
Pick up where you left off. Your courses show how far you've got in each lesson, with the one to resume a click away.

A closer look at Amos: how a question turns into a course, what it does with each subject, and the research it’s built on.

Frequently asked questions
What is Amos and how does it work?
Ask about anything you’re studying and it builds a lesson: a short explanation, interactive visuals you can drag and play with, and practice questions that check you’ve got it. Add your lecture notes and lessons follow your course, using its notation and citing its pages.
What should I use it for?
Understanding a topic from your course, catching up on a lecture you missed, working through a whole module in order, or practising before an exam. It’s there to help you understand the material, not to do your assignments for you.
How much does it cost to use?
Free has an allowance every 5 hours and every week, enough to try it on your own course. Pro and Max give you more room for a full term of study. See the plans above.
