Features
Purple Crayon helps instructors, TAs, and program leads give rich, rubric-based feedback without spending every evening buried under essays.
From first-year writing courses to upper-year seminars, Purple Crayon keeps your feedback consistent, transparent, and fast — across assignments, sections, and semesters.
Upload drafts and get immediate suggestions on clarity, structure, and mechanics, tuned for academic writing instead of generic spell-check.
Align AI feedback with the criteria you already use in class. Score each dimension and reuse rubrics across courses and semesters.
Share evaluation schemas, align on rubrics, and keep feedback style consistent across large courses with multiple graders.
Organize evaluations by class, assignment, or cohort so you can quickly find past feedback and see how students are progressing.
Store evaluations in one place and export scores and comments into your LMS or gradebook with minimal copy-paste.
You choose how AI is used in your course. Keep control over rubrics, scoring, and how feedback is presented to students.
Spin up your first evaluation schema, upload a sample essay, and see how Purple Crayon handles your real rubric and writing tasks.
