The browser only receives what you are about to see. The server does the rest, so an old laptop opens the timetable as lightly as a new one.
Enrolment, groups, timetable, attendance and payments in one place. Twenty-one modules, one licence, one login for the whole school.
No card required. We migrate your spreadsheet data for you.
Not a feature list, but what happens in a school from morning to evening: money, lessons, exercises, the whiteboard and online classes. All in one licence.
The payment plan issues instalments by itself, a payment link goes out on the due date and each payment settles the oldest charge. You only see the result: who paid and who is behind.
Attendance, topic, grades, homework and notes on one group screen. Every entry has a change history, and parents and students see the same in their own panel.
Fifteen exercise types, from gap-fills to a spoken answer. Students get their result at once, and it goes into the journal by itself.
She to school.
The capital of Poland is...
“children” is the plural of “child”.
A shared board like Miro, but built for language lessons: sticky notes, vocabulary tables, exercises marked by the server and AI that lays out a board from your lesson description. No separate accounts, no extra fees.
The room grows out of a class in the Schedule, on our own video server in Poland: the teacher opens it, students join from their journal, and the group board sits next to the tiles.
You don't buy features piece by piece. Payments, journal, e-learning, whiteboard, CRM, staff and settlements in one package, and you pay for the size of your school.
35 modules in one subscription - from groups and lessons to finance, e-learning and CRM.
You do not start from scratch. Coming from LangLion, ActiveNow, Librus, Vulcan or a spreadsheet? We move your students, groups and team: automatically, by file, or we do it for you.
Groups, students, contracts, orders: every list is the same table. Light and fast, you edit it in the cell, stretch columns and add your own. It is not a spreadsheet: a record has rules, and the school has one source of truth.
An enquiry from the form or straight from your own site, the funnel, bookings from a link and surveys. It all lands in one system, with no spreadsheet on the way.
Your link and QR code for Facebook or a business listing. The enquiry lands in the funnel with the consent and a copy of its wording.
Got your own site? An API key sends its enquiries straight into the CRM.
You set the stages and channels. A win creates the student or company in one dialog.
A page with a QR code: the client picks a day, a time and a teacher, and the school approves the slot. Free times work themselves out from the teachers' schedules.
A question builder with a live preview, a link that needs no account, and results counted by the database, not in a spreadsheet.
Schools don't buy computers for a register. The office runs a laptop from years ago, a parent checks the timetable on a cheap phone, a teacher ticks attendance between lessons. Cerium is built for those screens, not ours.
The browser only receives what you are about to see. The server does the rest, so an old laptop opens the timetable as lightly as a new one.
Click and the screen is there. No spinner, no "please wait": the engine underneath answers before the screen can blink.
Every school is walled off from the others in the database itself, not just on screen. A reach for someone else's data bounces off the wall before anything leaves the server.
The comment is the one part of a report that cannot be counted, so it was what held back a whole group's reports. Now AI drafts it from what is already in the journal, and the student's name never leaves the school.
Journal data passes through pseudonymisation, the model drafts a comment without the name, and the teacher gets it back with the student's name to approve.
Reception asks how to record a cash payment, a teacher asks where the lesson topic goes. The assistant in the bottom-right corner of the panel answers with numbered steps, button names exactly as on screen, and a link to the right screen.
Answers are built from guides written together with the panel. The AI model only summarises them, it doesn't guess.
Students, amounts and names from the database never reach the model. Conversations aren't stored anywhere.
When your role or a module doesn't allow something, you hear it right away, not after five steps.
A sure match gets a ready guide instantly. You can ask in Polish or English.
And that is still not everything Cerium offers.
Based on competitors' public offers and price lists (as of July 2026). Librus and Vulcan are registers for state schools - a different category from the course plan, shown for context. Spotted something outdated? Write to us and we will fix it.
Cursium is a language learning platform from the makers of Cerium: courses built from small interactive exercises, plus real teachers for 1:1 lessons. Students practise between classes at their own pace and earn points for every lesson.

Straight answers to the questions we hear most often - about pricing, modules and migration.
The Pro plan is 40 € net/month (up to 100 students and 10 teachers), the School plan is 85 € net/month (up to 300 students, 30 teachers and 3 locations), and Enterprise is priced individually; VAT depends on your country and VAT number. Every plan includes all 35 modules - no paid feature add-ons. A private primary school has a separate plan: 1 € net per student per month with a minimum of 100 students, teachers included. Schools from Poland pay in złoty: 170 zł, 370 zł and 4 zł net respectively.
All 35 modules - payments, e-learning, the interactive whiteboard, CRM, HR, the timetable - are in every plan. There are no paid add-ons and no premium tier. You pay for the scale of the school, not for features.
Yes. Settlements (a tab of the Team module) count teachers' hours automatically from the lessons they ran, applies the rates and extras from their contract and closes the month with one amount to pay out. No more adding up tutors' hours by hand at the end of the month. The bank transfer itself stays with you.
Yes. Cerium e-mails a payment link before the due date, charges the instalment from a saved card and reminds about overdue amounts - the guardian hears about it before the instalment becomes overdue.
Yes. The Schedule shows lessons by day, week and month, by teacher or by room, and you drag a lesson to another day, person or room. Rooms live in the school's catalogue, assigned to a location. The system does not detect two lessons in one room yet: you see them on the room's lane, but without a warning.
Yes. The School plan covers up to 3 locations (addresses) in one school: a shared team and students, with the timetable narrowed to a location. With Enterprise you get several separate schools on one account: each with its own team, students and timetable, switching in one click and one invoice for all of them.
Yes. From LangLion the school moves itself from the Integrations tab: team, groups, students, guardians, companies, rooms and upcoming lessons, with duplicate detection. From other systems such as ActiveNow, and from spreadsheets, we load students, guardians and groups from CSV files. We help with the migration or do it for the school.
For private schools and education centres: language schools, tutoring, music and arts, dance, sports and driving schools. There is also a separate plan for private primary schools with the Classes module (pilot). For state schools, where Librus and Vulcan are the standard, the legal opinion and the pilot are under way: see the Primary school page.
Yes - 14 days of the full version, no credit card. Book a free demo and we will show the system on your groups, lessons and payments.
Yes. A 1:1 lesson is a group with one student, and the Bookings module (beta) lets a teacher set a weekly window in which the student books a slot in their own panel; the booking becomes a lesson in the Schedule and the Journal. A per-lesson payment plan bills by the number of lessons, and teacher payroll counts the lessons held. Lesson packages with an expiry date („10 lessons valid for 3 months”) are not available today.
The school’s notice rule decides: a lesson cancelled in time disappears from the timetable, and one cancelled late stays as „Cancelled late”, so it counts towards the per-lesson plan instalment and the teacher’s payroll. A lesson can also be moved in the Schedule, or a make-up lesson added. When a teacher is away, a substitute is set for a single day.
Yes. A make-up is a separate kind of group lesson („Add lesson”: make-up or extra lesson), visible in the Schedule and the Journal. Creating a new lesson series for the group does not delete make-ups.
The panel is designed from phone width up and runs in the phone’s browser. The teacher sees the day’s lessons on the Dashboard, opens the group in the Journal and marks attendance (present, absent, late with minutes, note), enters the topic, the syllabus unit, homework with a material or a link, and a remark. Students and guardians with an account see it in their panel and get a notification plus one digest e-mail. An App Store and Google Play app with push notifications is in preparation; today Cerium runs in the browser.
Yes. Every group has a level from A1 to C2, the syllabus has a level, the Schedule shows it, and the course certificate carries it. The level belongs to the group, not the student: there is no history of a student’s level changes today.
Yes. The test is a set of questions from Exercises with level thresholds, shared under a public link with no account needed. The candidate fills in a form and the test, their level is frozen, and the CRM gets an enquiry with a note such as „Placement test: 72 %, B1”.
Yes, in the Syllabus module: textbook, level and units in order, one syllabus per group. At each lesson the teacher marks the unit covered, and „Where we are” is taken from the latest lessons held and shown in the group header, also to a substitute.
Available: online payments and card instalment charges through Stripe (the school’s own account, Stripe Connect), VAT invoices in KSeF through Fakturownia, wFirma, iFirma or inFakt, e-mail (instalment, homework and report messages), video lessons built into Cerium, CSV import and export, and an API key for an enquiry form on your website. Not available today: Zoom, Google Meet, Microsoft Teams, Google Calendar, Apple Calendar, SMS and WhatsApp.
No. Reminders and updates go by e-mail and as notifications in the panel; Cerium has no SMS gateway.
Not today. The timetable lives in the Schedule and on the Dashboard; there is no calendar subscription (iCal) and no sync with Google Calendar or Apple Calendar.
