Our Values
The principles that guide how we build tools for academic integrity
Transparency
Clear evidence and explanations, no black-box decisions. Every detection is backed by revision history and concrete examples.
Fairness
Revision-aware detection that supports student growth. We focus on understanding writing processes, not just flagging outcomes.
Privacy
FERPA-friendly data practices and student data protection. Your students' work is secure and never used for training models.
Education-First
Built by educators, for educators and students. We understand classroom realities and design tools that actually help teaching.
Built for fairness and transparency
We design detection grounded in revision history, with clear explanations and privacy-respecting data practices.
