OwlCAD for Schools — free, private, browser CAD for K-12

Safe by design, not bolted on

• Students are pseudonymous — a display name only. No email, no password, no birthday collected.
• Built under-13-safe by default for COPPA, with FERPA and state student-privacy laws in mind.
• Analytics is off for student sessions, and student work is never public.

Teacher-only AI

• Only teachers can use AI generation — a student’s prompt or image never reaches an AI provider.
• That keeps all child data away from third-party models, the sharpest edge of COPPA.
• Teachers generate a model and drop it into an assignment or the class gallery.

Free for classrooms

• Classrooms, rosters, assignments, submissions, and a class gallery — free, for everyone.
• Students join with a class code and a display name. No app to install; it runs in the browser.
• A step above the basics: parametric history, fillets, exact dimensions, STEP, print-aware export.

Built for districts

• A school/district account pools an AI budget across its teachers and centralizes data rights.
• Sign a Student Data Privacy Agreement (NDPA-aligned); we record it and hold the line on retention.
• Admins can review and export their school’s data, and request bulk deletion at any time.

Sign a DPA

Your district reviews and signs our Student Data Privacy Agreement. We record it against your school account.

Add your teachers

Teachers get OwlCAD accounts and create classes. Students join with a code — no personal data required.

Teach and build

Assign work, collect submissions, and let students model and print. Optional pooled AI credits power teacher generation.
