Fix what's broken about group projects
Without intervention, group work produces learned dysfunction. CoStudy adds the structure that makes real collaboration possible.
Individual accountability
CoStudy makes individual effort measurable, creating the balanced reciprocity that makes collaboration work.
Early intervention signals
Short formative check-ins throughout the semester surface problems early, so you can intervene before the final presentation.
Reduce bias in evaluation
Behavioral questions, anonymization, and aggregation minimize bias and ensure equitable assessment.
From dysfunction to competence
Students rate themselves, then see how peers rated them. The gap between self-assessment and peer feedback reveals blind spots and drives real growth.
Balanced reciprocity
Formative check-ins keep everyone honest throughout the project. Summative assessments at milestones capture cumulative contributions for grading.
Set up in 30 minutes
Create your course, add your students, and launch your first assessment in under an hour.
Growth starts with seeing yourself clearly.
Most peer evaluation tools treat evaluation as a measurement device: collect ratings, generate a score, move on. CoStudy is built on a different hypothesis. The evaluation process forces the self-examination that drives real growth.
Research shows students who give feedback outperform those who only receive it. When you articulate what you see in someone else's work, you're forced to examine the same behaviors in yourself. Every evaluation cycle closes the loop between self-perception, peer perception, and growth.

What professors say
“Group projects are an essential tool for teaching content and developing student skills today, but many things can derail their success. CoStudy solves all these problems by helping students learn how to become more valuable team members through personal growth, feedback, and reflection.”

“Transitioning to an exclusively online format has been extremely challenging for our undergraduates. CoStudy has provided us a fantastic platform to think about how we guide our students through online learning as well as how we can use technology to mediate our teaching efforts.”
