Polish an Essay's Prose Without Touching Its Argument
This page is for prose you wrote yourself that has gone stiff — the third draft that reads like a form, not a chat assistant's first attempt. Academic Mode is selected. Everything it changes stays highlighted.

Stiff prose is not the same problem as machine prose
Both problems share one symptom: low variance in sentence length, clause after clause built to the same pattern. The causes differ. Machine-typical prose comes from a model predicting the likeliest next token; stiff human prose usually comes from over-editing a paragraph until every hedge and qualifier has been sanded off along with the voice, or from a habit picked up in formal schooling. The tell-tale symptoms are specific: nominalisation, where the implementation of replaces implementing and turns a verb into a noun that needs its own verb; passive voice used to avoid naming who did something, rather than because the agent is genuinely unknown; and a paragraph where every sentence opens with a subordinate clause, so the reader waits for the main verb four times in a row. None of these is wrong on its own. Stacked across a page, they read as a document that is trying not to sound like anyone.
What a register pass changes and what it leaves
Academic Mode carries three settings tuned for this. It does not contract — “it is” stays “it is” — because a formal essay that suddenly says it's reads like two people wrote it. Its sentence-splitting threshold sits at forty-two words rather than the standard thirty-four, so a long sentence doing real subordinating work is left alone and only the ones that have genuinely run past readability are broken. And it inserts a hedging opener at the second sentence of the passage rather than an informal one, because a qualified claim is what a scholarly register expects and a flat one reads as a press release. Separately from any Mode setting — on every Mode, every Plan — a sentence carrying a parenthetical or narrative citation, a numeric reference, a footnote marker, a figure or table reference, or a block quote is not sent to the model at all, and comes back exactly as you typed it. What that does not cover is an unusual citation style: detection is a set of patterns, not an understanding of referencing, so a style it does not recognize can still be rewritten — which is exactly why the Highlights over every sentence carrying a citation are still worth reading before you copy anything back.
Why the Highlights matter more here than anywhere else
On every other Tool Page, the highlighted diff is a courtesy. Here it is closer to necessary, because you are the one person who cannot read this text with fresh eyes. You already know what you meant to say, so a rewrite that changes the meaning without changing the shape of the sentence is exactly the kind of edit you will skim past — your own memory of the argument fills in the gap a stranger would trip over. The specific risk is a hedge flattened into an assertion: a sentence that said the evidence suggests a link becomes the evidence shows a link, which is a stronger and different claim than the one you were prepared to defend. Reading every highlighted span, not just the ones that look interesting, is the only way to catch that kind of change before it goes out under your name.
What this is not
It is not proofreading. It will not catch a misspelling, fix a comma splice, or correct a citation style, because those are mechanical errors and this tool works on phrasing and rhythm instead. It is not a grader: it has no opinion on whether your thesis is defensible, whether your evidence supports your claim, or whether your third paragraph contradicts your first, and it will not tell you any of that. And it will not rescue a weak argument by making it sound stronger — a well-phrased bad argument is still a bad argument, and a marker who is paying attention will notice the gap between confident prose and thin evidence faster than they would notice awkward prose around a solid one. Fix the argument first. This page is for what is left once the argument is right.
About Essay Polisher
Will it rewrite my own voice out of the essay?
Not if you read the Highlights. It changes phrasing and sentence boundaries, the same as the other rewrite pages, and every altered span stays marked in the output so you can put your own wording back wherever it matters more to you than the smoother version does. The place stylistic voice tends to survive worst is the opening of a paragraph, so check those first.
Does it fix spelling and punctuation?
No. It works on phrasing, sentence length and register, not on mechanical correctness, so a misspelled word or a missing comma passes through unchanged in both directions. Run a spelling and grammar checker separately, before or after — the two tools solve different problems and neither substitutes for the other.
Can I run only one paragraph?
Yes, and for a targeted fix that is often the right size. Sentence-length variance is measured across whatever you paste in, though, so a single paragraph gives the engine less to vary against than a full section does — a whole essay run at once will generally read more evenly than the same essay run one paragraph at a time.
How is this different from the AI Essay Rewriter?
The AI Essay Rewriter is built for a full draft that came out of a chat assistant: a first pass to break machine-typical rhythm across an entire coursework submission. This page is for a draft you wrote yourself that survived several rounds of your own editing and came out stiff — the same Academic Mode, aimed at a narrower and later-stage problem.
