NudgeLearn
Grade a class set from a photo, in minutes
Snap or upload a class set: worksheets or essays, handwritten or typed. Every problem marked, every mistake explained in one line, every essay scored criterion by criterion on your rubric. You keep the pen. 20 items a month free.
Hi PH. I'm a solo builder and NudgeLearn started because grading is the part of teaching that eats the evening. Not the hard part, the long part: a hundred pages where you write the same correction forty times.
You point a camera at a finished page, or upload a class set, and it comes back marked. Every problem gets a mark, the correct answer, and one line saying what the student actually did wrong, not just that they were wrong. Essays get scored criterion by criterion against a rubric: 86 real published rubrics ship built in (Common Core, state writing rubrics, AP FRQ, 6+1 Traits), or you import your own.
The part I care most about: the teacher stays the grader. Every score is editable, every criterion is editable, and the marks are suggestions on a page you sign off. It is not a replacement for reading your students' work.
On accuracy I would rather show the number than claim one. Texas publishes real student essays with the scores its trained examiners gave them. We graded all 78 of them, grades 3 through 8, on the same engine any account uses: 9 in 10 came back within one point of the examiner, and agreement with the examiners was 0.78 QWK against the 0.70 that is generally accepted for automated marking. Method and limits are on https://nudgelearn.app/grader/ac..., including what it does not cover.
Free is 20 graded items a month, no card. Pro is $30/mo for 400 items with a roster, analytics and export; Max is $50/mo for 1,000, which is a full secondary load. Google Classroom and Canvas import and grade passback are in early access, turned on per account.
There are also 81 free math lessons and a printable worksheet library on the site, which is where the whole thing started.
What I would most like from this crowd: try it on a page of real handwriting and tell me where the marking is wrong. That is the feedback I cannot get from anywhere else. Ask me anything.
