For students preparing for exams
StudyOS brings mock exams from lecture PDFs, flashcards with spaced repetition and a readiness score per exam into one product. Orby is the tutor that cites the source page behind an answer.
The study loop
Start from your own lecture material. Practice with mock exams, return to scheduled flashcards and use cited tutoring to revisit the source. A readiness score is a study signal, not a guaranteed exam result.
Status and platform
StudyOS is in early access, with iPhone first. The waitlist sends one email when it is ready. The public site does not currently offer an App Store download.
Your files
Files uploaded to StudyOS are used only to build your own study kit, not to train models. A citation makes an answer easier to check; students should still compare it with the original material.
