About DueHelper

DueHelper reads your own Canvas LMS data and shows it in a single popup, so you don't have to click through course pages to find out what's due. FOUR SECTIONS - Upcoming — everything due in the next 21 days, grouped by day, colour-coded by urgency (red within 3 days, orange within 7). - Awaiting grading — work you've already submitted that hasn't been marked yet, with how long it's been waiting. Canvas doesn't surface this anywhere. - Undated — assignments your instructor has published without a deadline. - Completed — graded work with scores and per-course totals, collapsed by default. WORKS AT ANY UNIVERSITY Enter your school's Canvas domain once. The extension asks Chrome for access to that one domain, and nothing else. NO ACCOUNT, NO TOKEN, NO SERVER DueHelper uses the Canvas session you're already logged into. There's nothing to sign up for and nothing to copy-paste. Your data never leaves your browser — there is no backend, no analytics, and no tracking of any kind. QUIET BY DESIGN Canvas's own planner mixes lecture times and tutorial slots in with actual deadlines. DueHelper filters those out so the list is only things you have to do. You can also hide courses you don't care about from the settings page. Interface available in English and Simplified Chinese, following your browser language. --- Not affiliated with Instructure, Inc. Canvas is a trademark of Instructure, Inc.
