Grounded feedback, not generic praise

Feedback that cites the essay, not boilerplate

The grader references specific sentences and phrases from the paper when flagging strengths and issues. No generic "needs more evidence" with nothing to back it up — every claim is tied to the actual text.

  • Per-criterion scores with written feedback

  • Strengths and improvement lists grounded in the text

  • Revision-oriented, actionable suggestions

  • Honest grading, not grade inflation

Argumentative essay · Grade 10 · 84/100

Strength

The opening paragraph's hook — "Every third student sits down to lunch alone" — creates immediate stakes and anchors the argument in concrete experience.

Suggestion

The third body paragraph references "studies show" without citing any. Adding one specific source (author + year) would strengthen the credibility significantly.

About this tool

The AI paper grader teachers actually trust

The free AI paper grader teachers use for Sunday-night stacks and revision-day drafts. Paste any student paper — essay, research paper, response, reflection — and get rubric-based scoring with grounded, revision-oriented feedback. No sign-up, no credit card, no daily limit.

Feedback that actually helps students revise

Most AI essay graders return generic praise or generic criticism without pointing to anything in the actual paper. This tool cites specific sentences and phrases when flagging strengths and issues — so a student reading the feedback can see exactly what to revise and where.

  • Strengths and suggestions grounded in the essay text

  • Per-criterion scores that add up to the overall grade

  • Revision-oriented suggestions, not judgment

  • Fair, honest grading — not inflated to avoid complaint

Built for real classroom use

Paste the rubric you'd use with a real grader and the tool scores against it. Leave it blank for default criteria. Works for K-12 English, history, science essay responses, and college-level research papers. Output format matches whatever scale the rubric specifies — percentage, points, or letter grade.

Pair with the full GradeWithAI product for scale

The free grader is for one-at-a-time grading and quick teacher sanity checks. When you're grading 120 papers at once, GradeWithAI's paid product syncs with Google Classroom and Canvas, scales to entire classrooms, and pushes grades back — same underlying AI, built for scale.

Honest about what AI grading is and isn't

Every report is a first-pass draft. Teachers should review before returning feedback to students, especially on high-stakes work. The goal isn't to replace teacher judgment — it's to save the hour spent on the first read-through and point you directly at the sections that need your attention.

More impressive though is that it corrects student answers not simply using a pre-written answer, but by following the thought process they've pursued.

I've really enjoyed using the GradeWithAI program. It saves me a ton of time, especially when I have class sizes of 35 or 36 students times five.

GradeWithAI doesn't just grade. It gives the student reasoning as to why every point is awarded or not awarded. That is a very valuable thing for the students.
