About CULPA on Vergil

This creatively named chrome extension brings professor ratings from CULPA (Columbia University Professor Review Database) directly into Vergil, Columbia's course registration platform, so students don't have to always be switching tabs. When you browse courses on Vergil, CULPA on Vergil automatically detects instructor names and it displays a rating badge next to each one, showing: - Average rating (out of 5) - Nugget status: Gold (4.0+), Silver (3.5+), or Bronze (3.0+) - Number of reviews on CULPA - A direct link to the professor's full CULPA profile Badges appear both in course section rows and in the instructor autocomplete dropdown when searching. Hover over any badge for a quick summary. Click it to open the full CULPA profile in a new tab. Privacy: CULPA on Vergil collects no personal data. It does not track you, log your searches, or send any information about you anywhere. The only network requests it makes are to culpa.info to fetch professor ratings. Ratings are cached locally on your device for 24 hours to minimize requests. Nothing is stored in the cloud. Permissions: - Storage: caches professor ratings locally to reduce API calls - Host access to vergil.columbia.edu and culpa.info: required to read instructor names and fetch ratings Built by two Columbia students, Trew Smith and Holden Bronson, cuz they're goated. Not affiliated with Columbia University or CULPA.
