Less Policing. More Teaching.

Proof of Thought, Not Just Proof of Work

What is it?

This open-source toolkit helps teachers assess whether students understand the ideas in their writing—regardless of whether AI was involved. Instead of detecting AI use, it promotes reflection, comprehension, and deeper learning in every assignment.

Validate Concepts

Upload a student essay and get AI-generated questions that test their understanding of what was written. It works whether the essay was AI-assisted, student-written, or both.
