CoGrader
CoGrader lets K-12 teachers grade written assignments with rubric-aligned scores and feedback drafts for every student. It handles essays, constructed responses, and short answers against your rubric or a state-aligned template. Teachers review and approve every grade before students see it. The free Starter plan covers 100 student submissions per month with no credit card.
Most general AI chatbots will score a pasted essay on a generic scale. CoGrader grades a full class against the rubric you choose, including STAAR, CAASPP, B.E.S.T., Regents, and AP College Board templates, and routes every result through teacher sign-off before export. That workflow is what separates it from dropping text into ChatGPT, especially when you need consistent scores across 30 submissions and one-click export back to Google Classroom.
Classroom teachers use CoGrader for everyday essay assignments and open-ended questions. School and district teams run writing benchmarks across thousands of responses and get scored analytics the same day instead of waiting on hand-scoring vendors. ELA educators grading AP DBQs, LEQs, or literary analysis also get rubrics trained on official College Board scoring guides.

Can CoGrader detect AI-written student essays?
Yes, on School and District plans. CoGrader flags likely AI-generated content and shows the evidence behind each flag for teacher review. No detector is fully accurate, so flags are advisory and the teacher makes the final call.

No. CoGrader drafts scores and feedback, but nothing reaches students until the teacher reviews, edits, and approves each grade. The educator keeps final say on every submission.
