Got a diagram? In a few minutes it's a click-around class project β no accounts to create, no cloud to trust, nothing to pay for.
A catalog is just a file stored on your own device. There's no cloud database behind it, and students don't need to sign up for anything.
A whole class can label one diagram together, live, on the same file at once β using the free, optional collaboration server.
A file saved in September opens exactly the same in June β no renewal, no expiring account, no breaking update to worry about.
The same Editor and Viewer everyone else uses β just switched to "Education" mode, which relabels Buy/Cart into Learn more/Collection.
Turn the same diagram into a self-check quiz: students tap an answer, it turns green or red at once with a short explanation, and they can print their results. Practice, not a proctored exam.
Rooms, hidden objects and a finale behind a password: an escape game made of ordinary catalogs, built in the same Editor with no code. A class can make one as a project. Play The Haunted House β Β· All games
This demo catalog has "Education" mode switched on: notice the toolbar says "π Collection" instead of "π Cart", and each part says "Learn more" instead of "Buy" β same app, same file format, just relabeled for a classroom.
Tap an answer: it turns green or red at once, with a short explanation. Question 7 needs two answers. The score builds up as you go. It's a self-check for practice β the answers live inside the file, so it isn't a proctored exam.
Drop in a diagram β a cell, an engine, a map, a machine β place a few hotspots, and it's a class project. Works offline after you first open it on a computer, tablet or phone, and keeps working after the bell rings on the last day of school.
