In their own words
CrowdGrader
CrowdGrader is a web service for students to submit homework and peer-grade classmates’ work while instructors oversee assignments and keep control of final grades. It combines peer assessments into a consensus grade for each submission and removes outliers. A student’s crowd-grade reflects both the grade received and how accurately that student grades other submissions. Students can create reports, math, or code in the built-in editor, or upload files such as ZIP archives. Reviews are anonymous: reviewers do not see authors’ identities, and uploaded files are renamed. Instructors can monitor similarities through clusters and side-by-side submission comparisons. Institutional subscriptions include optional LMS integration, access monitoring, and long-term data retention for auditing. Student work is transmitted over HTTPS; Google authentication uses only the user’s email address for identification. The free instructor-sponsored plan covers up to 20 students per assignment. Other listed options include $2.99 per assignment for up to 35 students, $6.99 for up to 100, and $13.98 for unlimited students.
