You can get ChatGPT output most of the way to sounding human with better prompts and a short manual edit pass, before you ever reach for a dedicated humanizer tool. It won't close every gap a rewriting tool would, but for a lot of writing it's enough on its own, and it costs nothing but a few extra minutes.
What to actually put in the prompt
Asking for "more natural" writing rarely changes much, since that instruction is too vague for the model to act on differently. Specific constraints work better: ask it to vary sentence length noticeably within the same paragraph, to avoid restating the same point in a summary sentence at the end, and to write the way you'd explain the idea out loud to a colleague rather than the way you'd write a formal report. The more concrete the instruction, the more the output actually shifts.
The words ChatGPT overuses, and why removing them helps
ChatGPT defaults toward a small set of adverbs and hedging phrases: "significantly," "notably," "ultimately," "in essence," "it's important to note." None of them are wrong, but their overuse is one of the more recognizable patterns in AI-generated text, because the model reaches for the same statistically safe phrasing repeatedly. Going through a draft and cutting every adverb that isn't doing real work, then reading the sentence again without it, usually tightens the writing and removes the pattern in the same pass.
Search for "-ly" words specifically and cut any that don't change the sentence's meaning if removed.
Delete transition phrases that restate what the previous sentence already said ("In today's world," "When it comes to X," "It's worth noting that").
Read the paragraph aloud. Adverb-heavy, hedge-heavy sentences are usually audible before they're identifiable on the page.
What prompting and editing can't fix on their own
Even a well-prompted draft still leans toward low-perplexity, predictable phrasing at the sentence level, because that's how the underlying model generates text regardless of instructions. For a deeper look at where prompting alone hits a ceiling and a dedicated rewriting pass does more, see why AI humanizers don't work (sometimes), which covers the same rhythm-and-specificity mechanism from the other direction.
The gap usually shows up on longer or higher-stakes writing, an essay, a published article, anything that's actually going to be scored. Short pieces and casual drafts often don't need anything beyond a good prompt and a manual pass.

Frequently asked questions
Can a good prompt alone make ChatGPT text undetectable?
Not reliably for longer or high-stakes writing. Prompting changes surface-level word choice and structure, but the underlying model still generates statistically predictable phrasing at the sentence level, which is what detectors actually measure.
Which words should I search for and remove first?
Adverbs ending in "-ly" that don't change the sentence's meaning if cut, plus stock transition phrases like "in today's world" or "it's important to note." Both are among the most recognizable patterns in AI-generated writing.
Is editing a draft myself better than using a humanizer tool?
Neither replaces the other completely. Manual editing catches word-level patterns you can hear yourself; a dedicated tool is faster at restructuring rhythm across a longer piece. Many people get the best result combining both.
