The argument
Turn your notes into next semester's tuition.
Students around the world are earning real money by depositing study materials they already wrote. No filming, no audience to build — just the work you already did, on a public shelf with a price tag.

Lecture notes, exam guides, flashcards, condensed summaries and study briefs across hundreds of subjects — every entry written by a student and indexed by university and course.
Every entry in the catalog has a free preview of the first pages, and a star rating from buyers. If a document isn't worth it, the community says so before you spend.
Opening a borrower card is free. The catalog is free to browse. You only pay when you check out a specific document — and the author sets the price.
Sign up, open your desk, click Deposit. Drop a PDF, set a price, connect Stripe — and earn every time another student checks it out.
Authors keep up to 80% of every checkout. Rates start at 70% and rise as your circulation grows. Payouts settle daily to your bank through Stripe.
