Gradescope to Cal

Automatically sync Gradescope assignments to Google Calendar. Privacy-first: all processing happens locally. Perfect for students managing multiple course deadlines. Built by a UC Berkeley EECS student.

Features & Capabilities

Stop forgetting Gradescope deadlines. Sync them to Google Calendar automatically.

Built by a student who kept missing deadlines across 6 different courses.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS

  1. Visit Gradescope once - the extension learns your courses
  2. Connect Google Calendar (one-time, 30 seconds)
  3. Done. Assignments sync automatically, even when you're not on Gradescope.
No manual work. No forgotten deadlines. Just check your calendar.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ TRUE BACKGROUND SYNC (New in v2.0)

✓ Checks Gradescope every 30 minutes automatically ✓ New assignments appear in your calendar without visiting the site ✓ Smart detection syncs immediately when you do visit ✓ Works silently in the background - set it and forget it

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ GRADE TRACKING

✓ View all your grades across courses in one place ✓ Track submitted vs pending assignments ✓ Quick access from the extension popup

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ FULL CUSTOMIZATION

✓ 11 calendar colors - organize by class or priority ✓ Flexible reminders - none, 1 day, 1 day + 1 hour, or custom ✓ All-day or timed events - your preference ✓ iCal export for Outlook, Apple Calendar, or any calendar app

Every event includes a direct link to submit on Gradescope.
