## What is CruX.|渠?

CruX.|渠 is a native course-knowledge and study-planning companion for eligible Tsinghua University and Peking University students and alumni.

With CruX you can:

• Ask questions grounded in class notes, course facts, and schedule sources, then inspect the supporting references;
• Search course information and student-contributed course experience;
• Browse THU and PKU schedules, add courses to a personal planner, and record decisions such as added, considering, or excluded;
• See explainable course picks based on explicit choices, saves, visits, and public course evidence inside CruX, then build a conflict-free audit draft;
• Add dated schedule events directly to Apple Calendar with write-only permission. CruX does not read existing events and still supports image and iCalendar-file sharing;
• Search onboarding, course selection, campus systems, and campus-life guides;
• Restore Ask history and your planner across devices, with saved content available during temporary network failures.

CruX is independent and is not affiliated with, endorsed by, or an official product of Tsinghua University, Peking University, or their schools and departments. Always confirm course selection and campus arrangements in the schools' official systems.
