You're In Business

CalenDue is a promising student-focused productivity tool that won 1st place at Co.Hack 2025. It demonstrates strong real-world utility by addressing a genuine pain point with automated syllabus parsing and two-way calendar sync. However, the submission is heavily penalized for hyperbolic, unsubstantiated claims ('most people have used my product', '500000 marketcap') and lacks verifiable active user metrics. While the technical concept is solid, the absence of realistic traction data restricts its current evaluation to the minimal traction tier.

Description

CalenDue is built for students to keep course deadlines under control. Instead of managing another app, upload your syllabi or connect Canvas, and our AI parses assignments, quizzes, labs, and exams into clean, reviewable events. With true two-way sync to Google and Apple Calendar, CalenDue updates existing events rather than creating duplicates, and it keeps dates accurate when instructors make changes. Our conflict engine flags overlapping deadlines and exams, and the fast review workflow lets you approve, edit, or bulk-fix items in minutes. The result is a single, reliable source of truth in the calendar you already use, with no drift, no clutter, and less juggling. Built by University of Saskatchewan students and won 1st place at Co.Hack 2025. CalenDue cuts setup time from hours to minutes and helps students and instructors avoid last-minute surprises.
