ChatGPT assignment checker & writing check

ChatGPT assignment checker

What the ChatGPT assignment checker does

This app checks coursework against the writing habits typical of ChatGPT, OpenAI's assistant, and gives you the specific flags rather than one blended score. It's aimed squarely at what you actually want to know before a deadline: does this assignment read like ChatGPT wrote it, and why.

It runs as a server tool. Whatever you paste goes to our AI server, gets scored against ChatGPT's patterns, and the flagged result comes back to the page. You get 5 free checks in any rolling 24 hours, no account and no plan behind it.

Workflow

How to run the ChatGPT assignment checker in three steps

Use it on a finished draft, right before you upload the file, not on a half-written outline.

1. Paste your assignment

Drop in the full document, headings included. More text gives the check a clearer read.

2. Run the check

The text goes to our AI server once, gets scored, and the flagged patterns land back on the page.

3. Read the flags, not a score

Each pattern ships with a plain reason. Use that to decide what, if anything, needs rewriting.

The real tells

How ChatGPT's writing shows up inside coursework

A handful of habits carry over from ChatGPT's default style into a submitted document, and they read differently there than in a chat window.

A summary that repeats the intro

'In conclusion' followed by a restatement of the opening, rather than a closing point that adds anything new.

The rule-of-three reflex

Three examples for nearly every claim, evenly weighted, even when one of them is clearly weaker than the others.

Throat-clearing openers

'It's important to note that' announcing a point the assignment needed made directly.

Templated paragraphs

Claim, explanation, example, in the same order down the page, which reads as formulaic rather than argued.

Bolded mini-headers mid-paragraph

A short bolded phrase acting like a heading inside running prose, a carryover from chat-style formatting.

Lists where prose was expected

A short-answer question answered as a numbered list, when the question wanted a running explanation.

Self-review checklist

What to check before you submit, beyond the pattern flags

The checker reads phrasing. The rest of a good self-review is on you, and it matters just as much.

Answered the actual question

Match every paragraph back to the brief, not to a related question from the course material.

Right format for the task

Report, case study or essay, with whatever headings your course specifies.

Referencing lines up

Every in-text citation should have a matching entry in the reference list, in the required style.

Word count and balance

One bloated section at another's expense is usually the first thing a marker flags manually.

Every rubric line addressed

If it's graded, it should be visible somewhere in the document.

Straight answer

Will this check keep my assignment out of trouble?

No, and this app is not going to pretend it can. It reports patterns typical of ChatGPT's writing, nothing more. It has no affiliation with Turnitin, GPTZero or Copyleaks, and it cannot tell you what any of them would return on the same document.

Institutions write their own rules on AI assistance, and they differ between courses. Check yours before you submit anything. Use this app to see your own writing from the outside, not as a guarantee about what happens after you hand it in.

Why flags happen

Why false positives happen

Several kinds of legitimate student writing trip the same flags for reasons that have nothing to do with ChatGPT.

Second-language students

Formal transitions and cautious, explanatory phrasing are exactly what academic English courses teach, and get flagged for it.

Rigid house styles

A rubric that expects a fixed claim-example-explanation structure produces text that reads like a model's, for its own reasons.

Genuinely well-organised writing

A clean, formulaic structure required by a course is not evidence of anything on its own.

Heavily edited drafts

A piece redrafted many times by a careful writer can end up more uniform in rhythm, which reads similarly to a pattern flag.

If it happens to you

What to do if your own assignment gets flagged

Evidence of process beats arguing with the tool.

Keep every draft

Outlines and earlier versions are the clearest proof a piece was built, not generated whole.

Leave version history on

Docs, Word and most platforms track this automatically. Don't switch it off while a question is open.

Be ready to explain your choices

Talking through why a paragraph is structured the way it is is hard to fake.

Ask what was actually flagged

A named pattern can be discussed. A bare score can't.

Who it's for

Who uses the ChatGPT assignment checker, and when

Usually the writer, checking their own work, at a few predictable moments.

Right before submission

A last look to catch anything that reads differently than you intended.

After brainstorming with ChatGPT

Confirming that ideas discussed with the assistant did not carry its voice into your final draft.

Writing centres

Supporting a student's own review of their own submission, one input among several.

Second-language students

Learning which of their own habits might read as pattern-heavy before a marker sees them.
