About Us

PrairieLearn is an open-source assessment platform, originally developed at the University of Illinois and now used at top universities across the US, including Berkeley, Princeton, Michigan, and UIUC. We empower mastery-based learning and large-scale assessment with an emphasis on reliability and innovation. We are like a "power-user" version of Gradescope/Canvas/Moodle. We’re also developing AI tooling in the product, including LLM agents to help instructors create content, and vision-language models to help grade student work. This is practical, user-facing AI work with real-world impact — not a research sandbox.
