Canvas is a cloud-based learning platform. Connect it to your Dropbox account to easily attach files to courses or submit assignments without switching apps.
Instructors: Centralize your course content in Dropbox, where you can keep it secure. Then, upload lecture slides, videos, reading assignments, and more to a course in Canvas. You can spend your time on academics instead of on managing your files.
Students: Turn in assignments quickly, without having to sign in every time. Upload files from within Dropbox, or while you’re in Canvas.
