CoGrader
Rubric-based AI grading for essays and written assignments, synced with your LMS.
About
CoGrader grades essays, constructed responses, and short answers against your rubric — or 30+ preloaded standards templates covering STAAR, CAASPP, Regents, and AP — and drafts feedback for every student. It pulls assignments directly from Google Classroom, Canvas, or Schoology and pushes approved feedback back, including inline comments in Google Docs and OCR-graded handwritten work.
The teacher always reviews and approves grades before students see them, which is the right design. The free Starter plan covers 100 submissions a month; Standard is $15/month billed annually, and it is built for writing-heavy subjects rather than STEM or scanned exams.
