This is a planning estimate, not a guarantee. Keep teacher review as the final step before sharing feedback with students.
Use the estimate carefully
Time saved depends on essay length, rubric complexity, and how much teacher editing each student needs. The safest workflow is to draft quickly, review carefully, and share only the comments you approve.
