AI Grader Pro vs Rubrical

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.

Rubrical is a web-based AI teaching platform for geography departments. Teachers can upload PDF, Word, or image assessments and mark schemes, or create rubrics themselves. It marks answers criterion by criterion against the selected rubric, presents reasoning and evidence, and drafts feedback; a teacher approves every mark and feedback item before delivery to students or writing to an LMS. Rubrical also drafts specification-aligned objectives, timed lessons, and tiered resources grounded in checkable sources. Approved results produce assessment-objective breakdowns, question-difficulty rankings, at-risk flags, misconception heatmaps, and plain-English queries. Work can come from Google Classroom, Microsoft Teams, scans, or student hand-in links. It supports AQA, Edexcel, OCR, WJEC/Eduqas, and user rubrics. Feedback can be simplified, enlarged, shown in OpenDyslexic, or translated. Core school data is stored in London. Rubrical says student and learning-platform data are not used to improve AI models.
