Turn chaotic university class announcements into a calm semester schedule.
A local-first, zero-server academic radar for university students.
🌐 Official Website • 📱 Launch Web Companion (PWA) • 📦 Download Center • 🚀 Latest Release
QuizRadar is a private, on-device academic radar built for university students. Every semester, students navigate disorganized communication streams: professor emails, LMS posts, Teams chat messages, and PDF lecture slides. Announcements arrive with ambiguous date phrases like "Class Quiz 1 next Tuesday, not this week", causing missed deadlines and exam scheduling panic.
QuizRadar solves this entirely on your device:
- Fuzzy Anchor Engine: Scans course updates and resolves ambiguous natural language dates into exact timetable lecture and tutorial slots.
- Academic Conflict Radar: Flags overlapping deadlines, exam pileups, and heavy assessment weeks ahead of time.
- Study Recommendations & Readiness Score: Computes real-time preparation readiness per course, recommending focused study topics and practice quizzes.
- Zero Server Architecture: All parsing, OAuth token management, and timetable storage remain strictly on your physical machine. No central server, no telemetry surveillance, and zero cloud lock-in.

- Zero Server Architecture: QuizRadar operates no servers, relays, or central databases. All data remains on your physical device.
- Zero Fabricated Data: If a room, instructor, or time is unannounced, QuizRadar renders
"—"rather than hallucinating placeholder lecture halls. - No Embedded Secrets: Authentication uses standard PKCE OAuth 2.0 without embedded client secrets.
- Bring-Your-Own-Key (BYOK) AI: Optional Google Gemini AI features use your personal API key via direct HTTP headers. When offline or unconfigured, QuizRadar automatically uses fully local, deterministic heuristics.
