In their own words
OpenRubric
OpenRubric is a managed judging service for hackathons, handling submission imports, scoring coordination, timeline review, and rankings. Organizers can import projects from a public Devpost URL, upload a CSV, or enter them manually. They set weighted criteria and tracks; judges score each criterion, may add comments, and keep independent records. OpenRubric calculates winners by track and overall, and event data can be exported to CSV at any time. When configured with a GitHub token, it scans repository dates, commits, and contributors as timeline signals for organizers to review. It is not a cheating detector or AI judge: people make scores and award decisions, and the product does not automatically deduct points. AI can draft short summaries for judges, and organizers can switch that off without affecting ranking calculations. The hosted service says it retains event data while an account or event is active and does not sell data or use it for advertising. A partner event is listed at free for one event in kind; managed events are billed at $50 to $100 per event, with larger events quoted before agreement.
UniRubric
UniRubric is a higher-education AI assessment platform that drafts rubric-anchored grades with quoted evidence for lecturer review. Lecturers can upload rubrics as DOCX, PDF, or plain text, then add student submissions individually or as a class. Each grade remains a draft until a lecturer reviews, edits, and approves it; it is not released to a student beforehand. Institutional integrations include Canvas, Moodle, and Blackboard through LTI 1.3, while the contracting page also lists Brightspace. A faculty lead dashboard shows rubric calibration across markers and can draft a meeting agenda and schedule a calibration meeting. Customer data, submissions, rubrics, and grading runs are region-pinned to Sydney, Australia, under standard operating conditions. The maker states that data is encrypted in transit and at rest, and customer work is not used to train or fine-tune models. Deleted assignments are removed from production within 24 hours and backups within 35 days; grading-run audit logs are retained for seven years. The Lecturer Free plan provides one lifetime marking job; Lecturer Premium costs $15 per month.
