AI writing feedback designed for student growth — rubric scores, specific revision suggestions, grade-banded tone. Built to coach, never to write for them.
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.
Feedback uses age-appropriate language and rubric vocabulary that matches the student's grade band — without dumbing it down.
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.
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.
No. Student writing is processed for inference only and not used to train any underlying AI model.
