HomeworkGrader.com - Grade a full class of handwritten papers in seconds

Hey Product Hunt 👋 I built HomeworkGrader because grading handwritten homework is the part of teaching that follows you home — nights, weekends, the same stack of fraction worksheets every week. Here's how it works: 1. Upload your answer key (or snap a photo of a completed copy — it builds the key for you). 2. Add student papers — drag in PDFs, or show a QR code, scan it with your phone, and snap photos of the stack. They stream in live. 3. Watch it grade. It reads each student's handwriting, marks every problem right or wrong with a reason, annotates the page, and fills your gradebook — in seconds, at ~99.9% accuracy. You get per-question accuracy, who's struggling and on what, a CSV gradebook export, and downloadable marked-up papers. One teacher told me it caught a paper she'd mis-marked because "it doesn't get tired." Another said she watched a movie on a Tuesday for the first time since 2009. It's free for teachers, and I'd love your honest feedback. What would make this a no-brainer for your classroom?
