Rumi has video guides that cover how to use many of its features. Some of these features are not covered in the Tufts-created help documents, others are supplemental to the Tufts guides on this site.  

Advanced features include:

Real-Time Class Insights - this dashboard can give you a snapshot of student progress. 

Peer Review - Ask students to give each other feedback. 

Continuation assignments - Create future assignments based on past submissions, allowing students to reuse text from those assignments without confusing the originality score and allowing students to incorporate feedback and improve the quality of their final submission. 

Group Assignments - Collaboration assignments. This is still in Beta at the time of writing. 

AI-assisted Rubric and Feedback - Tufts has not yet evaluated these features. AI can create a rubric and then use that rubric to give students feedback during the writing process.
