In Notion, the maintenance is yours
A teacher template in Notion is a database someone else built, with a rate formula, a relation between student and lesson and a calendar view. It works until you need a one-off lesson at a different price, a make-up lesson with no charge or different billing days for each student. From then on, you are the one adjusting the formulas. In Aulency, those rules are already part of the system.
Automations need a billing workflow
Notion has recurring templates and database automations, with features that vary by plan. Student invoices, PIX QR codes and payment tracking require configured rules and connected services. Aulency includes the invoice and PIX in the lesson workflow; the student reports payment and the teacher confirms it.
A shared page does not replace the student portal
You can share a Notion page with the parent, but they see everything on it, and you manage the permissions one by one. In Aulency, each student has their own access and sees only their lessons, invoices and reports.
