For language schools
Cerium combines an online gradebook, finances, CRM and built-in video lessons in one system. Built for the realities of running a language school — from a single tutor to a network of hundreds of students.

Every language school fights the same battles. Here's how Cerium answers each.

Card payments via Stripe, PDF invoices, automatic installments. Money straight to the school's bank account.

Library of auto-graded exercises: fill-ins, matching, sentence ordering. Per-blank feedback, ready to share.
