AI writing feedback

AI Writing Feedback Built for Student Growth

AI writing feedback designed for student growth — rubric scores, specific revision suggestions, grade-banded tone. Built to coach, never to write for them.

Coaching, not auto-writing

WriterSpark never generates the student's draft. The AI's role is to ask questions, model thinking, and give pointed feedback — so the writing stays the student's own.

  • No auto-generated drafts
  • Socratic question prompts
  • Coach explains every score

Rubric-aligned, grade-adapted

Feedback uses age-appropriate language and rubric vocabulary that matches the student's grade band — without dumbing it down.

  • Elementary tone
  • Middle school precision
  • High school analytical vocabulary

Specific, not generic

Every comment points to a specific phrase in the student's writing. No 'good job' filler — every score comes with what to revise and why.

  • Phrase-level highlighting
  • Revision targets per draft
  • Actionable next-step suggestions

Common questions

Which AI model powers WriterSpark?

WriterSpark uses Anthropic's Claude Sonnet 4.5 via the Emergent integration platform. The model is tuned with educator-written system prompts that enforce the 'coach, don't write' rule.

Is student writing used to train AI?

No. Student writing is processed for inference only and not used to train any underlying AI model.
