What makes your product unique?

Clast.io's answer:

AI automation — AI builds curriculum, lesson plans, reports, insights, and flags at‑risk students.

Real‑time sync — Every update instantly reflects across all modules and roles.

Clast ID — A unique academic identity that follows a person across years and institutions.

Role‑based dashboards — Tailored views for teachers, admins, finance, HR, students, and parents.
