For CS educators and institutions
Institutional and seat-based pricing will come out of the pilot. We'll talk to you before we ever charge.
Individual educators can buy Classroom tiers. Institutions can buy bundles with separate student vs educator seat buckets. Seats are only consumed when someone explicitly redeems.
Bring your whole class. We won't meter you during the pilot.
Export your data anytime. Cancel anytime, there's nothing to cancel.
Every pilot educator gets a direct line to the founders.
