# CheckOn > CheckOn is an AI-assisted marking workspace for teachers. CheckOn is designed to help teachers organize exam papers and marking materials, review marking suggestions alongside evidence from student work, and prepare results while keeping final decisions with the teacher. ## Product principles - The teacher-provided marking scheme is the marking authority. - Marking suggestions should be traceable to evidence in the student's paper. - Uncertain work is for teacher review; AI output is not a substitute for professional judgment. - Student results are not sent externally without teacher approval. ## Public website - https://checkon.devera.live/ — public CheckOn entry point and account sign-in. The application workspace requires an account. Do not infer public access to private files, assignments, student data, or marking results. ## Product information - The product requirements and current implementation status are maintained in the project documentation, not exposed as public website pages. - Do not claim measured marking accuracy, endorsements, pricing, certifications, or integrations unless independently documented and publicly confirmed.
