ProfLens — Know Your Professor Before You Register Stop registering blind. ProfLens overlays RateMyProfessors ratings directly onto your university's course registration page — right next to every professor's name, right when you need it. No copy-pasting names. No switching tabs. Just instant, inline ratings while you shop for classes. ⭐ What You See Every instructor gets a badge showing their RMP rating, difficulty score, would-retake percentage, top student tags, and a direct link to their full profile — all in a clean tooltip that appears on hover. 🏫 Works Everywhere Banner, PeopleSoft, Coursicle, and most other university registration systems. If your school's on RateMyProfessors, ProfLens works on it. ⚡ Smart & Fast Ratings are cached locally so repeat visits are instant — even after restarting your browser. No redundant lookups, no waiting around. 🎯 Rating Threshold Warnings Set a minimum rating in settings. Any professor below your cutoff gets a red outline on their row so low-rated sections are impossible to miss. 🌙 Dark Mode Ready Badges automatically adapt to whatever color scheme your registration page uses. Light or dark, they always look right. 🔒 Private by Design ProfLens only contacts RateMyProfessors — nothing else. No tracking, no analytics, no data collection.
