How it works

From messy drafts to clear, rubric-based feedback

Purple Crayon fits into the grading workflow you already use: upload writing, choose a rubric, review the AI-assisted feedback, and share it with students.

Just three simple steps

Whether you’re evaluating ten essays or two hundred, Purple Crayon keeps each step predictable and easy to repeat across classes and semesters.

01

Upload writing

Bring in student work from your LMS, shared documents, or scanned pages. Purple Crayon extracts the text and prepares it for evaluation.

  • • Handle essays, reflections, short answers, and reports
  • • Keep original formatting available for reference
02

Choose or build a rubric

Select an existing evaluation schema or create your own, using the same criteria you already use when grading by hand.

  • • Criterion-level weights and descriptors
  • • Reuse rubrics across courses, sections, and years
03

Review and share feedback

Purple Crayon generates rubric-aligned scores and comments. You stay in the loop, editing language and scores before sharing with students.

  • • Instructor-editable comments and scores
  • • Export to your LMS or download as a report

For instructors & TAs

Use Purple Crayon as a grading copilot, not a replacement. You’re always in control of how rubrics are applied and how feedback is worded.

  • • Keep your own grading voice, with AI helping draft comments
  • • Standardize expectations across multiple graders and sections
  • • See patterns across a whole class, not just one paper at a time

For students

Students see clear, rubric-aligned feedback they can act on — instead of a wall of margin comments.

  • • Understand exactly which criteria need attention
  • • Get suggestions they can apply to the next draft
  • • See improvement across assignments and courses
