Some paragraphs do not need a word fixed. They need the order of the ideas changed, the topic sentence pulled to the front, and the rhythm broken up so the block stops reading like a list of equal-length lines. That is paragraph-level work, and a single-line edit cannot reach it. Paste a block, pick how hard to push, and TextSight rebuilds the flow while keeping every fact, figure, and citation in place. You see an Authenticity Score against our own detector so you can tell whether the block still reads AI-patterned.
Most rewrite tools quietly assume the unit is a sentence. But a paragraph can fail even when every sentence inside it is grammatically clean. The first skill is telling those two problems apart, because the fix is different.
A working paragraph makes one point and supports it. There is a sentence that states the claim, a few that back it up, and usually a line that closes or hands off to the next block. When AI writes a paragraph, the sentences are often individually fine but the structure is mushy: the claim is buried in the middle, two sentences repeat the same idea in different words, and the closing line restates the opener without adding anything. None of that shows up if you only look at one line. You have to read the block as a unit.
Rework the whole paragraph when the topic sentence does not match the support underneath it, when you find yourself rereading to figure out what the point was, when two or three sentences carry the same weight and the same length, or when the order of ideas forces the reader to hold a thought and pick it up two lines later. Those are arrangement problems. Swapping a word in one sentence does nothing for them.
Leave the block alone and fix one line when the paragraph already flows, the claim is clear, and only one sentence is clumsy, repetitive, or stuffed with stock AI vocabulary. Pulling apart a sound paragraph to rebuild it from scratch is wasted effort and risks losing a transition that was already working. If the scan highlights one red sentence in an otherwise clean block, the sentence rewriter is the right tool, not this one.
Run the block through the detector before you touch it. If the AI-pattern highlights are scattered across most of the sentences, the whole block is the problem and you rewrite the block. If a single sentence lights up inside an otherwise calm paragraph, that is a line-level fix. The highlight map turns a gut feeling into a clear call, and it stops you from rebuilding paragraphs that did not need it.
"Flow" sounds vague until you break it into the moving parts a paragraph rewrite can act on. These are the four levers that decide whether a block reads as one connected thought or four loose sentences.
The first sentence should tell the reader what the paragraph is about and what you are claiming. AI-written blocks often open with a soft scene-setting line and bury the real claim three sentences down. The rewrite pulls the claim forward so the reader knows where the paragraph is going from the first line. Everything after it then reads as support rather than as a hunt for the point.
The sentences after the topic sentence are there to back it up, and each one should add something the previous one did not. A common AI failure is two sentences that say the same thing with different words, which pads the block without strengthening it. A paragraph rewrite collapses that redundancy into one stronger sentence and reorders the remaining support so the most convincing point is not stranded at the end where readers skim past it.
Good transitions come from the logic of the ideas, not from a transition word bolted onto the front. AI models lean on a small stack of connectors (Furthermore, Moreover, In addition, In conclusion) because they are cheap glue. The rewrite removes that crutch and rebuilds the link from the content itself, so one sentence leads into the next because the ideas are actually related, not because a signpost word told the reader they were.
One of the strongest AI tells at the paragraph level is uniform sentence length. Three or four sentences all of roughly the same shape produce a flat, even cadence that human writers almost never sustain. The rewrite varies length deliberately: a short punchy sentence next to a longer one that does more work, then a medium line to reset. Read aloud, the rebuilt block has a pulse the original block lacked.
The clearest way to see paragraph-level rewriting is to watch the same content reorganised. The facts do not change. The order, the rhythm, and the connective tissue do.
Take a typical paragraph an assistant might produce: it opens with a generic framing line, states the actual point somewhere in the middle, props it up with two near-identical support sentences glued together by "Furthermore" and "Moreover," and closes by restating the opener. Every sentence runs to about the same length. Nothing is grammatically wrong. It still reads as a machine wrote it, because the shape is uniform and the claim is buried.
The rewrite lifts the buried claim into the first sentence so the reader lands on the point immediately. It merges the two redundant support lines into one that is sharper than either, then adds the second-strongest piece of support as a short follow-up. The crutch connectors are gone; the sentences now link because the ideas connect. The closing line does new work instead of echoing the opener. Sentence lengths vary, so the block has a cadence. Same facts, same figures, same citations: only the arrangement moved.
The numbers the paragraph cited are untouched. The named source is still named. If the block listed three items, all three survive, in a sensible order. Meaning preservation is the constraint the rewrite works inside, so the point of the paragraph is identical even though almost every sentence is reshaped. This is the difference between a rewrite and a rewrite that quietly drops half your content to look cleaner.
At the sentence level, the worst outcome of a careless rewrite is one awkward line. At the paragraph level, the worst outcome is a block that reads smoothly but no longer argues what you meant, because the reordering changed the emphasis. That is why the rewrite holds the claim fixed and only moves the support around it, and why the final read-through matters most for whole-block work.

The paragraph workflow has one extra step the sentence workflow does not: you read the whole block before and after, because the unit of judgement is the block, not the line.
Copy the full paragraph, from its topic sentence to its closing line. The rewriter needs the whole block to judge order, balance, and cadence; feed it one sentence and it can only do line-level work. Two or three closely related blocks can go in together if you want the transitions between them handled as a set, up to 5,000 characters on free.
Click Scan to see the baseline Authenticity Score and the sentence-level highlights across the block. This is the step that answers the block-versus-line question. Highlights spread across most sentences mean rewrite the block. A single lit sentence in a calm block means you are in line-level territory and the sentence rewriter is the better fit.
Light reshapes lightly and is right for technical or cited paragraphs where you cannot risk emphasis drift. Balanced is the default for most blocks and does the real flow work: reordering support, varying rhythm, rebuilding transitions. Maximum restructures hard and is for casual blocks where voice variation is welcome; read it carefully afterward because reordering is most aggressive there.
This is the step people skip and should not. Read the new paragraph top to bottom, out loud if you can. Check that the topic sentence still makes the claim you meant, that the support still backs it, and that the reordering did not shift the emphasis away from your real point. The facts will be intact; emphasis is the thing to verify by eye.
Run the detector again on the rewritten block. If the score moved enough and the read felt natural, you are done. If a stubborn sentence still reads AI, you can rewrite that single line on its own rather than re-running the whole block, which avoids undoing flow work that already landed. Free covers multiple passes within the monthly word quota.
Copy the finished block and paste it where it belongs, then read the sentence before it and the sentence after it to make sure the new block still hands off cleanly to its neighbours. A reworked paragraph can read perfectly on its own and still need a one-word tweak at the seam where it meets the next block. That seam check is the last thing block-level work asks of you.
Paragraph-level rewriting fits a specific moment in different kinds of writing: the point where one block is dragging down an otherwise finished piece.
An essay where the thesis and conclusion are solid but one body paragraph wanders is the classic case. The argument is there; the arrangement buries it. Reworking that single block, with the claim pulled forward and the evidence reordered, lifts the paragraph without touching the rest of the essay. Disclose AI assistance where your institution requires it, and keep the analysis your own.
In a blog post or landing page, one paragraph often reads flatter than its neighbours, usually because it was the part you wrote fastest or generated to fill a gap. Rewriting that block for rhythm and a sharper topic sentence brings it level with the rest of the piece, so the whole page reads as one voice instead of one good draft with a soft spot in the middle.
Technical and academic paragraphs go wrong by packing too many ideas into equal-length sentences with no breathing room. A Light-mode rewrite varies the cadence and separates the claim from the qualifications around it, which makes a dense block readable without softening any of the precision. The figures, the hedges, and the citations stay exactly as written.
When you start from an AI-written draft, the predictable weak point is the paragraph: blocks that are individually grammatical but uniformly shaped and softly argued. Reworking them block by block, scanning each before and after, is the practical way to turn a generated draft into something that reads like you wrote it, used responsibly and reviewed by you.
Being clear about the limits is part of using a rewrite tool responsibly. Here is what this tool does not claim to be.
No rewriter can promise that a block will clear Turnitin, GPTZero, Originality.ai, or any other tool, and TextSight does not make that promise. Those detectors disagree with each other and change their models, so a guarantee against them would be dishonest. The Authenticity Score you see here is measured against TextSight's own detector only, as a signal of how AI-patterned the block still reads.
Reworking a paragraph does not make borrowed content yours. If the underlying ideas or wording came from a source, cite the source; rearranging sentences does not remove the obligation to attribute. The tool is for improving the flow and voice of writing you have the right to use, not for disguising the origin of someone else's work.
The goal is a block that reads in your own voice with better structure, used in writing you are entitled to submit or publish. Framing it as a way to cheat a detector or sneak AI text past a marker is the wrong use and not what the product is built for. Honest use is clarity and own-voice polish, with disclosure where it is expected.
The flow rules, transition handling, and vocabulary swaps are tuned for English; output in other languages is not guaranteed and should be treated as a rough draft. And the rewrite preserves meaning by design: it changes order, rhythm, and wording, but it keeps your facts, figures, list items, and citations intact rather than dropping content to look cleaner.
