GradeLab is aimed at the people drowning in paper: university faculties, schools, coaching institutes, boards and government assessment programmes. Examiners upload a batch of scanned answer sheets and the platform's smart data mapping converts them into structured digital data, identifying student information, question numbers and answer regions automatically. Multilingual OCR covers 30+ languages, including Arabic and Chinese, and the system handles diverse formats from essays and mathematical working to chemical diagrams and multiple choice.
Once answers are extracted, grading runs rubric by rubric with teacher override available on any score with one click, plus AI moderation to compare and validate results. Because grading completes quickly, analytics appear immediately: class performance, question difficulty and student progress, plus institutional reports and exports suitable for accreditation evidence. Supporting modules cover question paper generation with LaTeX and diagrams, generating questions from source PDFs or past papers, online proctoring support and on-screen marking workflows for exam boards.
Deployment flexibility matters for institutions with data rules: GradeLab can run on-premise so exam data never leaves the campus. For software vendors, GradeLab exposes grading as an API so EdTech platforms, ERP systems and assessment products can embed rubric-based AI grading and handwritten recognition directly into their own interfaces.
Upload a batch of scanned scripts on Friday and return graded, feedback-annotated results to hundreds of students without weekend marking marathons.
Run structured, rubric-aligned evaluation across standardised exams with digital marking workflows and consistent scoring evidence.
Use the GradeLab API to add AI essay, exam and handwriting grading to an existing learning, ERP or assessment platform.
Generate institutional reports, attainment maps and audit-ready exports for accreditation bodies without manual data crunching.
