What is a paper grader?
How to grade a paper in 3 steps
- Paste the paper. Up to 40,000 characters, enough for most papers through college length.
- Add instructions and a rubric. Optional. Instructions such as “1000 words, 4 sources, APA” are checked automatically. Rubric lines such as “Evidence (25 points)” set the scale.
- Read the report. You get points per criterion, a requirements checklist, strengths and revision notes, ready to print or copy.
What the grade report includes
Your rubric or a default one
Scores follow your rubric points. Without a rubric it uses five default criteria worth 20 points each.
Requirement checks
Word count, paragraph count, number of sources and APA or MLA in-text citations are checked against your instructions.
Comments that quote the paper
Suggestions point to the paragraph and quote the sentence to fix.
Honest about limits
Criteria that need judgment, such as creativity or depth of analysis, are listed as not scored instead of guessed.
Automatic first pass vs teacher grading
| Automatic first pass | Teacher judgment | |
|---|---|---|
| Word count and sources | Checked exactly | Confirms quality of sources |
| Spelling and grammar | Common errors found | Style and nuance |
| Structure | Paragraphs, thesis and conclusion signals | Whether the argument works |
| Ideas and originality | Not measured | Required |

FAQ
What is a paper grader?
A tool that scores a written assignment against a rubric and explains each score. This one grades one pasted paper at a time and works in your browser.
How accurate is the paper grader?
Exact for word count, paragraphs and citations, and reliable for common spelling and grammar errors. Thesis, evidence and style scores are indicators based on signals in the text, so review them before using them as grades.
Does it use AI?
No. It uses rules and measurable checks, so the same paper always gets the same result and the text never leaves your device.
Can I use my own rubric?
Yes. Paste one criterion per line with its points, for example “Organization (20 points)”. Criteria it cannot measure are marked as needing your judgment.
What criteria does it use without a rubric?
Thesis and focus, evidence and sources, organization, style and clarity, and mechanics, each worth 20 points.
Does it check for AI-generated writing or plagiarism?
No. It gives writing and structure feedback only.
Can it grade handwritten papers?
No. Paste typed text.
What happens to the paper I paste?
Nothing is uploaded or saved. The checks run in your browser. Remove student names anyway if you share your screen.
How do I grade a whole class?
This tool grades one paper at a time. For class sets, use a grading tool that scores every submission against your rubric and syncs with your LMS.
