A rubric checker for college papers
Paste your paper and the assignment rubric. For every criterion you get an estimated score range, the sentences from your text behind it, and what is missing. Then three fixes, ranked by the points they are likely to recover. Fix, check again, see what changed.

01 — What you get
Below is an excerpt from a real check of a short argumentative essay (340 words plus references) against the library rubric. Every number comes with a sentence from the text. Quotes we could not find in the text are marked with a question mark.
Predicted score · not your instructor's grade
70–95 / 100 · 70–95 %
“This paper argues that Congress should pass a federal law setting minimum nurse-to-patient ratios, because ratios reduce patient mortality, lower nurse burnout, and in the long run save hospitals money.”✓
A clear, arguable position with three reasons that the body paragraphs then follow.
“Aiken et al. (2002) found that each additional patient assigned to a nurse was associated with a 7% increase in the likelihood of dying within 30 days of admission.”✓
Specific, cited, explained.
“which the Nursing Solutions report estimated at more than $50,000 per nurse.”✓
The cost claim rests on one uncited figure.
Next level: Give the cost argument its own evidence: a cited figure for turnover or adverse-event cost and a sentence on how it supports the thesis.
“Some hospital administrators argue that ratios are too rigid and that staffing should flex with patient acuity.”✓
The objection is stated fairly but generically and answered with logic, not evidence.
Next level: Name a real stakeholder or source for the objection and rebut it with cited evidence.
“A second reason is burnout.”✓
Topic sentences map onto the thesis; the cost reason has no paragraph of its own.
Next level: Split the cost argument out of the burnout paragraph with its own topic sentence.
“Hospitals in the United States are quietly running on empty.”✓
Clear, varied sentences; no errors that affect meaning.
“(Aiken, Sloane, Cimiotti, and Clarke, 2010)”✓
Four authors should be "Aiken et al., 2010"; inside parentheses APA 7 uses "&".
“(World Health Organization, 2019)”✓
A direct quotation with no page or paragraph number, and no matching reference entry.
Next level: Fix the two in-text citations, add the WHO reference, and cite or remove the unused Peterson & Gold entry.
1. Evidence and support+5
Turn the cost claim into a full evidence paragraph: cite a source for the turnover figure and explain how it shows ratios save money over time.
Where “which the Nursing Solutions report estimated at more than $50,000 per nurse.” ✓
Shape A cited study on RN turnover shows that replacing one bedside nurse costs far more than a modest staffing increase.
2. Counterargument and rebuttal+3
Replace the generic opposition with a named viewpoint and rebut the cost objection with cited evidence.
Where “Some hospital administrators argue that ratios are too rigid and that staffing should flex with patient acuity.” ✓
Shape Hospital associations argue that fixed ratios reduce flexibility (Source, Year); answer them with the mortality data from your second paragraph.
3. APA 7 citations and references+2
Add a paragraph number to the quotation, add a WHO reference entry, and cite or remove the unused Peterson & Gold entry.
Where “(World Health Organization, 2019)” ✓
Shape (World Health Organization, 2019, para. 2)
4 in-text citations · 5 reference entries

02 — How it works
01
Paste it or upload a .docx or .pdf. Fifty to twelve thousand words.
02
Paste it from Canvas or Blackboard, photograph it, or pick one of the library rubrics by assignment type.
03
Scores stream in criterion by criterion. Fix the three things that cost the most, check again, and see the delta per criterion.
03 — Honesty
We test the grader on essays that people have already scored with a rubric: 40 college essays scored by their instructors and 28 school essays scored by trained raters. Our estimate missed the real score by 11 % of the maximum on average, about 1.6 points on a 15-point rubric. That is why every score is shown as a wide range.
What it cannot do: know your instructor, read the assignment sheet you did not paste, or tell a 3.0 from a 3.5. Read the number as a rough band. Read the evidence (which criterion, which sentence, what is missing) to decide what to fix before the deadline.
04 — Rubric library
Each page explains what phrases like “synthesizes sources” mean and where students usually lose points. All rubrics
05 — Questions
No. It is a prediction of how a careful grader applying your rubric would score the draft, shown as a range. Your instructor decides the grade, and they may weigh things the rubric does not say.
Not precise. On 68 essays that people had already scored with a rubric (40 college essays scored by their instructors, 28 school essays scored by trained raters), our estimate missed the real score by 11 % of the maximum on average, about 1.6 points on a 15-point rubric. That is why every score is a wide range. Use it as a rough band; use the quoted evidence to decide what to fix.
No. Each fix says where and what to change. If it includes an example, the example is cut to one sentence before you see it.
It is kept 30 days so the report link can reopen it and you can check your next draft against it. Then the text, the rubric and every quote from your text are deleted. You can delete a check yourself at any time from under the report. Nothing is used to train models, and uploaded files are never stored.
Use a library rubric of the same assignment type instead of your course rubric. Your course rubric then stays on your device; your paper is still sent to the model provider to be checked.
