The moment

Your calendar was built for someone else’s lessons.

A parent asks to switch from Thursday to Wednesday for the rest of the term. That’s a dozen sessions to edit one by one, or a series to rebuild. A week later the tutor says the change was never made, and nothing shows who did what.

An owner running nine group courses plus one-to-one lessons rebuilds every schedule by hand, on paper.

What Pillar OS does / 02

Here’s how Pillar OS handles it

Built for one-to-one lessons as much as for groups and programmes, on one calendar. Change one session or the whole series in one popup; each session keeps its history of who changed what; clashes show before you save.

What Pillar OS doesn’t do yet

No two-way Google Calendar sync yet: families and tutors subscribe to a one-way feed. And no undo: the history shows every change, it doesn’t reverse it.

Good to know

Can I change the rest of a series at once?

Yes. Change one session or every session after it, in the same popup, and Pillar shows clashes before you save.

How much does Pillar OS cost?

One fee set by your active students, in Canadian dollars: $35 a month for up to 50, then by band up to $599 at 1,000. No fee per tutor, per lesson or per family login, and no share of your revenue. Texting, AI use, extra storage, a website, extra locations and the GoHighLevel connection are billed separately, only if you use them.

We use other software or spreadsheets today. How do we move?

On a setup call, we bring your students, families and tutors over from your export or your spreadsheets and book your first sessions with you. Past lessons and invoices stay in your old system’s export, so keep it.

Does it work in French?

Yes. The whole product runs in French or English, for your team and for each family in its own language. GST and QST are calculated on the invoice.

Get your centre running with us, in one call.

About 45 minutes: we load your students and book your first sessions together, in English or French.
