In their own words
AI Grader Pro
AI Grader Pro provides AI-assisted grading workflows for mathematics and other STEM subjects. Educators can create, refine, and apply rubrics, then review step-wise scores that account for partial credit and student solutions. The software processes question sheets and student answers in batches, and can export reports, summaries, and class-level outputs. Its local-first design is described as minimizing data leaving the user’s environment, but it can also send data to third-party AI services chosen by the user; those providers’ own terms and privacy policies govern processing. The product warns that AI-generated grading, feedback, and analytics may contain errors, leaving educators responsible for checking outputs and decisions. It runs on macOS and Windows. Recommended requirements are macOS 13 or later, or Windows 10/11 x64, with at least 8 GB RAM and 1 GB disk space. Full LaTeX output requires a LaTeX distribution. The Personal plan costs $120 a year and includes email support. The Team plan costs $299 a year, lists multi-user deployment and priority support, and is marked available in Q3 2026.
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.
