Crowdgrader is a peer assessment tool which does not have the ability to calibrate a students evaluation for accuracy or an online discussion board like Kritik.
With technology to ensure the accuracy of student evaluations along with providing students feedback on their evaluations, Kritik's platform outperforms Eduflow.
Piazza is limited to just a Q&A platform, whereas Kritik offers educators a discussion board plus AI-powered peer review making it the clear choice for educators.
Utilizing peer review for different types of assignments, Kritik is able to offer educators a platform that supports more types of assignments compared to Eli Review.
