Automated grading system to give you back hours

Attach unit tests and I/O tests to any assignment. Every submission is checked as soon as a student submits their assignments:

  • AI-generated unit tests and I/O tests on any assignment
  • Instant pass / fail feedback for students

View and comment on student code

Open any student's file, highlight the line you are worried about, and leave a comment on a line-by-line basis. Students reply in the same thread so they don't have to context switch:

  • Comment on the exact line
  • Back and forth conversations within a thread

Catch students cheating

Disable copy and paste to reduce cheating, monitor the class in real time, and replay any submission using the history slider:

  • Copy and paste can be disabled
  • Replay any submission step by step

Customize and edit everything

Have the opportunity to edit every assignment from starter code, test cases, and lesson plans:

  • Swap in your own instructions, examples, and hints
  • Adjust or replace anything that was generated for you
