Your labs, still running
Every explorable you have opened or generated sits in your hub, ready to pick up mid-experiment.
Your syllabus, already chosen
Class, board and exam track come back with you, so the library opens on your chapters and not on someone else's.
Your uploads and notes
Anything you turned into a lab from your own material stays in place — nothing is regenerated behind your back.
We only ever ask for your email and a password. No card is needed to look around, and we never sell what you study.
