Start with the educator's workflow.
Rubrix Co-grader works inside Microsoft Word because grading is easier when the tool meets the paper, rubric, and comments where instructors already use them.
About Rubrix AI
Technology should make teaching more human, not less.
Rubrix AI builds practical education tools that reduce repetitive work, strengthen feedback, and keep professional judgment with educators.
Make AI use visible.
PowerWriter treats AI as something students can use responsibly and explain, while preserving evidence that helps instructors understand how the work developed.
Keep the final call human.
Suggestions can accelerate review, but instructors decide what is accurate, what belongs in the paper, and what grade the work has earned.
Help us build the next version.
Educator feedback will shape Rubrix Co-grader before its wider release.
