About Semester OS
Semester OS reorganizes American University's Canvas so every course reads the same way.
Each course is sorted into five parts — Rules, Materials, Drumbeat (the recurring work), Projects, and Admin — and
everything is hung off the class sessions it belongs to: "before Thursday's WRT-100: read chapter 3, post a response."
• This Week — one timeline of your classes, with what's due before each one.
• Courses — every course in the same five-part layout, whatever the professor's Canvas looks like.
• Standing — your current grade per course and what you need on the remaining work.
• Changes — what moved: due dates changed, points changed, newly published, new and removed items.
• Ask — a heads-up bar over Canvas (Alt+A) for questions about your semester, answered by your own local assistant
if you run one; otherwise it searches your coursework.
It replaces nothing: submitting stays in Canvas, and every item links back to it.
Your Canvas data stays in your browser. No accounts, no servers, no analytics.
