Claude assignment checker

The job

What the Claude assignment checker is for

You have a draft due and you have read it so many times you cannot see it any more. Paste it here and you get back a written reading of it: what the sentences are doing, where the argument thins out, which paragraphs are carrying weight and which are padding.

It runs on our server, which is why the text leaves your browser. The budget is 5 runs per rolling 24 hours and up to 12,000 characters each, with an optional instruction of up to 300 characters. That budget is the reason to plan the passes rather than paste the whole thing five times.

The loop

How to check an assignment in three steps

Do this at the draft stage, when there is still time to act on what comes back.

Step 1

Paste the section you are least sure about rather than the whole assignment. There is no minimum length, so one paragraph is a valid run.

Step 2

Write the instruction before you press Analyze. "Is the second paragraph doing any work?" gets a sharper answer than no instruction at all.

Step 3

Edit against the findings, then run a different section next time. The Copy button takes the output out if you want it beside your draft.

Planning the passes

Five runs, spent well

The allowance resets on a rolling 24-hour window, so on a two-day turnaround you have ten runs. A sensible split for a long piece looks like this.

The introduction

The part markers read most carefully and the part most likely to be generic. Worth a run on its own.

The weakest section

You already know which one it is. Name your doubt in the instruction box and the findings land closer to it.

The conclusion

Usually written last and fastest, and usually the place where a draft starts restating instead of concluding.

A full pass, late

Once the sections are fixed, run as much of the assembled draft as fits in 12,000 characters to see whether it reads as one piece.

Still your job

The checks this assignment checker does not run

It reads the text you paste and has no access to anything else about the assignment. These four stay with you, and no page competing for this term does them either.

Answering the question

The brief is not in the box, so nothing here can tell you whether you addressed it. Read the brief against your draft yourself.

The rubric

No marking criteria, no predicted grade. The findings are about the writing, not about what a marker will award it.

Citations and sources

There is no reference index here. A citation is text like any other, so accuracy and formatting are unchecked.

Plagiarism

No database, no matching, no similarity report. This is not a plagiarism checker and cannot stand in for one.

Worth knowing

Why detectors flag real student writing

If you have run your work through an AI detector and been alarmed, read what those tools say about themselves. QuillBot names its own likeliest false positives as "heavily paraphrased writing and highly formulaic content, such as legal jargon or academic writing". Detector-checker.ai declines to publish Claude-specific tells because "polished answers, cautious tone, consistent sentence structure" also describe careful human writing.

That is most of what an assignment is supposed to be. It is the reason this checker produces findings rather than a percentage: a number invites you to edit until the number moves, which is a change to the score and not to the work.

If it happens

What to do if your assignment is flagged

Keep the evidence of how the work was made. Drafts, timestamps, notes, the browser history of sources you actually read, the version history in your word processor. That is the material that answers the question, and it exists before you need it or not at all.

Then follow your institution's policy rather than a tool's output. Grammarly makes the same point on its detector page, that complying with your institution's and educator's AI usage policies is the governing thing. And take QuillBot's advice over the instinct to rewrite: "If you used AI in your work, disclose it rather than revising to change a score."

Where it stops

What the assignment checker will not do

No score, no percentage, no highlighted sentences, no grade prediction. No file upload, so a Word document or PDF has to be pasted as text. No bulk queue, no API, no account and no stored history, which also means nothing to come back to later.

It will not tell you what Turnitin or GPTZero will report, and it makes no authorship claim of its own. We have no relationship with any third-party checker, and the checkers themselves say that editing shifts their results in either direction.
