Data stays in your school
Each school on an isolated tenant. We never train AI on school data.
Every school gets its own data boundary. We do not train any model on student work, and we do not share data across schools.
Human-in-loop, not human-replaced
Teachers always review before students see it.
AI drafts the marking; the teacher confirms or edits. The platform exists to give teachers time back, not to remove them from the loop.
