ClassGrade Pilot: AI rubric grading for teachers inside Google Classroom

Hey Product Hunt! 👋 I built ClassGrade Pilot after watching teachers lose entire weekends to stacks of essays and short-answer responses in Google Classroom. The idea is simple: open a side panel right inside Classroom, pick your rubric, and get a draft score plus rubric-aligned feedback for each student in seconds. Nothing is ever sent back automatically — you review, tweak, and approve every grade before it goes back to Classroom. What it does: • Works directly in Google Classroom (no copy-pasting between tabs) • Grades against YOUR rubric, not a generic one • Writes specific, criterion-by-criterion feedback students can act on • Teacher-in-the-loop: approve or edit every grade There's a free plan (30 student credits/month, 2 saved rubrics) so you can try it on a real assignment today. I'd love your feedback — especially from teachers: what would make this a must-have in your grading workflow?
