The AI grading teachers use in Examplary now works from your own platform too. Import your students' answers with POST /exams/{id}/sessions and set autoGrade: true, and each answer comes back with a score per rubric criterion, the reasoning behind it and feedback for the student.
Already imported answers without grading them? POST /exams/{id}/sessions/{sessionId}/auto-grade grades one session, and POST /exams/{id}/sessions/auto-grade grades the whole exam. Both pick up every answer that doesn't have a grade yet, including ones whose grading failed, and tell you how many they queued. While grading runs, answers show a gradingStatus of auto-grading-pending.
The new grading docs walk through the whole flow, from rubrics to results.
