How it works
Students individually search for logical flaws in the content you assign. No hints, no help—productive struggle.
After submitting, they see how anonymous peers analyzed the same content. The gap reveals blind spots.
You reveal the answer key. The class sees what everyone caught—and what everyone missed.
For professors
Upload a case study, article, or lecture. Our AI seeds logical flaws throughout—or identifies existing ones. You review and approve. Students hunt. You see exactly where they struggle.
