About this extension

Automatically sync Gradescope assignments to Google Calendar (Chrome, Brave, Edge compatible)

Read the publisher’s full description

Stop forgetting Gradescope deadlines. Sync them to Google Calendar automatically. Built by a UC Berkeley EECS student who kept missing deadlines across 6 different courses. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS 1. Visit your Gradescope dashboard - auto-extract detects assignments instantly 2. Connect Google Calendar (one-time, 30 seconds) 3. All assignments sync immediately (no waiting for next day) 4. New assignments auto-sync every 24 hours + smart sync triggers on new detections No manual work. No forgotten deadlines. Just check your calendar like normal. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ INTELLIGENT SYNC SYSTEM ✓ First-time sync: Instant calendar population when you connect (no 24-hour wait) ✓ Smart sync: Detects new assignments and syncs immediately (60-min cooldown) ✓ 24-hour auto-sync: Background sync runs daily to catch any missed assignments ✓ Manual sync: Trigger sync anytime from extension popup ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ FULL CUSTOMIZATION ✓ 11 calendar colors - color-code by class or priority ✓ Flexible reminders - none, 1 day, 1 day + 1 hour, or custom (up to 3) ✓ Display timing - show at exact deadline time or as all-day events ✓ iCal export - one-click .ics file for Outlook, Apple Calendar, or any calendar app Every event includes direct Gradescope submission links. Click event → click link → submit. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY-FIRST Everything happens in your browser. No servers. No tracking. No data collection. The extension only reads from Gradescope and writes to your Google Calendar. That's it. Open source: github.com/Matut-E/gradescope-to-Cal ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHO THIS IS FOR Students (or anyone using Gradescope) who are tired of: Checking 3+ different course pages for assignment due dates Missing deadlines because you forgot to check Gradescope Manually typing deadlines into your calendar every week If you use Gradescope + Google Calendar (or any calendar app), this saves you hours per semester. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ v1.9.1 • Currently used by 70+ students • Free • MIT licensed
