RedPen.ai
Grade a stack. Feedback in minutes.
Professors spend more time grading than teaching. RedPen.ai is the assistant grader you wish you had: upload a class's answer sheets — scanned PDFs, handwritten, typed — and it returns rubric-aligned scores plus written feedback for each student, traceable to the exact line they wrote.
/ What we built
The shape of it.
- 01
Bulk ingest. Drop a folder of scans; OCR and student matching happen in the background.
- 02
Rubric-aligned scoring. You supply the rubric, RedPen scores against it — never against itself.
- 03
Personalised feedback. Every student gets a written paragraph that points to their actual answer, not boilerplate.
- 04
Professor in the loop. Override any score, regenerate any feedback, export to a gradebook.
- 05
