Lumis turns your syllabus into your semester. Upload a syllabus and Lumis reads it: every assignment, every exam, every due date, laid out on a calendar automatically. No more copying dates into a planner during the first week of term. Most syllabi don't date everything. Six quizzes worth 60% of your grade, and not one date beside them. Lumis places those too, working from the term dates and your weekly schedule, and marks them clearly as estimates so you always know what came from the syllabus and what didn't. Confirm one in a single tap when your professor announces it. Then it helps you do the work. Lumis generates study guides, flashcards and practice questions from your real course material, not generic content. Ask it questions about your courses and the answers come from your own syllabus and notes. • Upload a PDF, Word or Pages file, or just photograph the syllabus • Assignments and exams extracted and scheduled automatically • Study guides, flashcards and practice questions from your material • An AI assistant that knows your courses • Focus timer, grade tracking and semester history • Home screen widget for what's due next Built by two college students who got tired of rebuilding the same planner every August. Lumis Premium is an auto-renewable subscription: $8.99 per month or $79.99 per year, with a 7-day free trial. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel it in your Apple Account settings.
