A ChatGPT paragraph rarely needs a whole-paragraph rewrite. Two or three sentences carry the AI weight, and the rest already reads human. TextSight scores every sentence individually, highlights the flagged ones, and rewrites only those — so the claim stays exact, citations stay intact, and your own phrasing in the surrounding sentences survives the pass.
Most AI rewriters treat a paragraph as a single unit and rewrite the whole thing. TextSight scores each sentence on its own, then rewrites only the sentences flagged above threshold. The shape of your paragraph survives.
When you paste a paragraph, the detector runs through it sentence by sentence and assigns an AI probability to each one. A typical 150-word ChatGPT paragraph shows two or three red sentences (high AI probability), one or two amber, and the rest green. The colour map lets you see at a glance which sentences are actually the problem.
You click Rewrite on the red sentences only. The green ones stay untouched. This preserves more of your own phrasing than a whole-paragraph rewrite ever could, and it avoids the flattening that happens when an AI rewriter is asked to rewrite text that already reads human. Most paragraphs need only two or three sentences fixed to clear threshold.
After the selective rewrite, the paragraph is scored again. If the Authenticity Score is still below threshold, the colour map shows you which sentences need another pass. Usually one round is enough. The pattern is fix two sentences, re-scan, and the rest of the paragraph drags above threshold because the AI burstiness signal has been broken.
A whole-paragraph rewrite changes everything in the block, including the sentences that already read human. That flattens the voice variance you spent time building. Sentence-level selective rewrites do the minimum work needed to clear threshold, which is faster, preserves more of your authentic phrasing, and produces output that reads less templated than aggressive paragraph-wide rewrites.
Different paragraph positions in a document carry different AI signatures. The AI rewriter treats each type with a slightly different focus.
The opening paragraph sets the voice for the whole piece, which is why the first sentence carries extra weight in sentence-level scoring. ChatGPT intros default to a hedged general claim followed by an outline of what the piece will cover. The AI rewriter targets that opener and the polite-assistant register (Certainly, Of course, Great question) that sometimes leaks into intro paragraphs from the prompt.
Body paragraphs are the most common AI rewriter target because they carry the bulk of the content. The dominant tells here are sentence-length flatness (every sentence between 16 and 22 words), vocabulary clustering (delve, leverage, robust appearing two or three times in 150 words), and the topic-sentence-then-three-supports template. Standard treatment focused on burstiness and vocabulary diversification clears most body paragraphs.
Conclusion paragraphs have a single dominant tell: the synthesis-with-forward-looking-metaphor pattern. "As we navigate this evolving landscape", "the path forward demands", "in an ever-changing world" — these closers appear in roughly one in three ChatGPT conclusions. The AI rewriter flags them aggressively and replaces them with a specific claim or an open question, both of which read distinctly human.
Transition paragraphs are short (often under sixty words) and almost entirely connective prose, which is exactly where ChatGPT defaults are heaviest. Furthermore, Moreover, In addition, Additionally — the transition phrase stack is concentrated here. The AI rewriter targets those phrases first and often replaces them with implicit connections or with specific connectors tied to the next section's content.
Structural tells like five-paragraph skeleton need a full essay to surface. Inside a single paragraph the classifier weighs four different signals.
Inside a single paragraph, ChatGPT clusters almost every sentence between 16 and 22 words. Human paragraphs typically contain at least one sentence under 10 words and one above 28. When five consecutive sentences sit inside the same five-word band, burstiness reads as zero and AI probability spikes. The AI rewriter breaks that cluster by shortening some sentences for emphasis and extending others by combining clauses.
Furthermore, Moreover, In addition, Additionally, In conclusion. Inside a 150-word paragraph that adds up to two or three transitional adverbs at sentence boundaries. Human writers skip transitions or use implicit logic. The AI rewriter replaces these phrases with specific connectors tied to the content or deletes them entirely where the paragraph already does the connecting work.
ChatGPT defaults to a paragraph structure of one topic sentence followed by exactly three supporting clauses or examples, then a transition out. Human paragraphs vary internal structure heavily, sometimes leading with the example and landing the claim at the end, sometimes alternating claim and qualifier. The AI rewriter breaks the template by shifting where the central claim lands inside the paragraph.
ChatGPT reaches for the same set of formal verbs and adjectives within a single paragraph: leverage, underscores, robust, navigate, multifaceted, foster. Three formal verbs in 150 words is a strong paragraph-level tell. Real writers vary register inside a paragraph. The AI rewriter swaps repeated formal verbs for plainer alternatives that fit the topic.

All three modes are available on every paragraph, but they target different scopes. Picking the right scope matters more than picking the right intensity.
Light is the recommended default for paragraph-level work. It rewrites flagged sentences in place, preserving the claim and the surrounding context the rest of your draft depends on. Right for body paragraphs that carry specific arguments, research summaries with citations, and any paragraph where the meaning has to stay exact across the rewrite. Score gains are smaller per sentence but the voice survives.
Balanced extends the rewrite scope to neighbouring sentences when the paragraph reads especially robotic. Use it when a Light pass leaves the paragraph still below threshold despite fixing every flagged sentence. The signal is usually that the green sentences are dragging the paragraph down because they sit in the same vocabulary cluster as the red ones. Balanced rewrites them too with moderate intensity.
Maximum runs the most aggressive rewrite across the entire paragraph. It produces the biggest single-pass score gain but takes the most liberty with rhythm and vocabulary, which can shift emphasis. Reserve it for sentences that did not clear threshold after a Balanced pass, applied only to those sentences. Running Maximum on a whole paragraph that already reads halfway human tends to flatten the parts you wanted to keep.
A useful default: Light on the red sentences first, re-scan. If still below threshold, Balanced on the same paragraph, re-scan. Only reach for Maximum if individual sentences are still stuck in the red after two passes.
Paragraph-level rewriting is the right tool for any longer-form writing where you generate sections with ChatGPT and want them to read like the rest of your document.
The most common pattern: you wrote the introduction yourself, you used ChatGPT to draft a paragraph explaining a concept you do not know well, and now that paragraph reads flat compared to the rest. Run the paragraph through TextSight, fix the two or three flagged sentences, paste it back. Repeat for each ChatGPT-drafted block in the essay. The voice of the rest of your essay carries the piece.
Blog-post writing in 2026 is often section-by-section with ChatGPT drafting opening hooks, transition paragraphs between sections, or summary boxes at the end. Each of those is a paragraph-level AI rewriter target. The Light mode default usually clears them in one pass.
Research-summary paragraphs are particularly vulnerable to the lack-of-specifics tell because ChatGPT defaults to general claims when summarising sources. Running the paragraph through the AI rewriter often surfaces the missing concrete anchor (a year, a number, a name) that needs adding. The colour map identifies which sentence is too general; you add the specific yourself; the re-scan usually clears the block.
Outreach emails, cold-pitch emails, and long internal updates that you drafted with ChatGPT carry the polite-assistant register heavily. Paragraph-by-paragraph rewriting cleans them up faster than rewriting from scratch, particularly because the underlying content (the offer, the ask, the context) is often correct, and only the prose register needs adjusting.
