Frequently asked questions
Is Krater safe to use with student data?
For lesson planning and rubric design — yes, fully. For feedback on student work, we recommend anonymising student names (Krater never trains on your data, but anonymising is good practice). For district-wide rollouts with student-identified data, our Enterprise plan provides DPA, EU hosting and dedicated security review.
Will my school district approve Krater?
Many districts already use Krater for teacher prep. For procurement, we provide a DPA, SOC 2-aligned controls, EU hosting options, and a security review document. Contact our Enterprise team — most district approvals take 2-6 weeks.
How is Krater different from MagicSchool or Eduaide?
MagicSchool and Eduaide are great purpose-built tools wired around a small set of models. Krater is the general AI workspace underneath: every frontier model (GPT-5, Claude Opus 4, Gemini 3 Pro) plus image, voice and video. You get unlimited use cases — not just the templates one vendor happened to ship.
Can I use Krater with students directly?
Krater accounts are 18+. For student use, we recommend running activities through your account or through a school-managed deployment. Our Enterprise team can advise on classroom rollouts.
How much does Krater cost for a teacher?
Pro at $20/month gives 1,500 credits — comfortable for a heavy planner with image and slide generation. Ultra and Max suit instructional coaches and department leads. School and district plans are quoted via Enterprise.
