Materials belong to you
No one-vendor trap
Data and teaching materials are yours. You can also run the platform on your own school server.

One assignment to rule them all: print, online and practice. A unique variant for every student.
Open and light. Runs on any server — even the school’s.

AI can help — but it mustn’t sit behind the wheel. It saves routine work; accuracy and the rules stay with you.
