Flashcards and quizzes from your course, not a stranger's.
Upload lecture slides, handouts and your own notes. Lumis builds decks and practice tests from what your professor actually covered, in their terms.
Now on the App Store
Your whole semester, illuminated.
Upload your syllabus and Lumis lays out every deadline, weighted by what it is worth. Then it turns your notes and slides into flashcards and practice quizzes for that exact course.
Free for up to three courses. Premium comes with a 7 day free trial.
Every deadline is a star. The ones that count shine brightest.
This is what Lumis sees after reading four syllabi. Each class becomes a constellation across your semester, and a 30% final burns brighter than a 2% quiz. Tap any star.
Bigger star, bigger share of your grade
Read from the syllabusDates, grade weights and exam windows, even the schedule hiding in a table on page six.
Weighted, not just datedYour plan puts effort where it moves your grade, so the big ones never sneak up.
Yours to fixIf Lumis reads something wrong, correct it in one tap. Always check key dates against the syllabus.
Syllabus week, handled in one sitting.
Your syllabus already holds the whole semester. Lumis is built to read it that way.
1
Drop in your syllabi
Snap a photo or upload a PDF or Word file for each class. You can also share one straight in from Mail, Files or Safari.
2
Your semester appears
Every assignment, quiz and exam lands on one calendar with its grade weight, and reminders show up before things are due.
3
Study what's coming
Add your notes, slides and readings. Lumis turns them into flashcards and practice quizzes for that exact course.
A planner that also studies with you.
Planners know your deadlines but can't teach. Flashcard apps can quiz you but have no idea when your midterm is. Lumis does both.
One calendar, every class
All your deadlines in one place, sorted by what is actually due next.
Home screen widget
Your next deadlines are on your home screen before you even open the app.
GPA tracking and prediction
Enter grades as they come back and see where the semester is heading while there is still time to change it, including what you need on the final.
An AI tutor that knows your class
Ask it to explain a concept, walk through a problem or summarize a lecture you uploaded. Answers come from your course material first.
Focus timer
Study sessions logged against the class you are actually working on.
Reminders that start early
Nudges timed to the work, so a big paper gets started before the night before.
Works offline
Calendar, assignments, notes and timer keep working with no signal. AI features need a connection.

Built by two students at the University of Miami.
Every August we had the same conversation. Why does getting through a semester take five apps? A calendar for deadlines, a flashcard app for studying, a spreadsheet for grades, a notes app, a timer, and a syllabus sitting in a PDF none of them ever read.
So we built the one we wanted. Upload your syllabi once and Lumis becomes your calendar, your tracker, your flashcards and your tutor, all for the same course.
We upload our own syllabi every semester and test every feature on our own classes first. If it doesn't survive a Miami finals week, it doesn't ship. Lumis is made by Coral Code, the studio we started to build software we wished existed.

Questions, answered.
Will it read my professor's messy syllabus?
That's the whole point. Lumis handles PDFs, Word files and photos, including schedules buried in tables, dates without years and "Week 9" formats. If it misses something, fix it in one tap. AI can make mistakes, so always check important dates against the original.
My professor only posted the syllabus as a page in Canvas. Now what?
Open it in Safari, tap Share, choose Options, select PDF, then share it into Lumis.
What can I upload besides the syllabus?
Lecture notes, slide decks, readings, handouts, past problem sets and your own notes, as PDFs, documents or photos. Everything you add makes that course's flashcards and quizzes sharper.
What happens to the files I upload?
They're used to build your semester plan and study materials. We don't sell your data, and you can delete any file, any course or your whole account from inside the app. The details are in our privacy policy.
Is it allowed at my school?
Lumis is a study tool, not a ghostwriter. It organizes your semester and quizzes you on your own material. Rules on AI vary by course, so follow your school's policy for graded work.
Is there a version for my laptop?
Lumis is on iPhone today, with the home screen widget and share sheet import. A version for your laptop is in the works.
How do I cancel Premium?
Apple handles billing, so cancel in Settings, then your name, then Subscriptions. Deleting your Lumis account does not cancel the subscription on its own.
Midterms are coming. See them first.
