How to make AI writing sound human: 12 edits that actually work
AI drafts are a fast way to get words on the page, but readers can usually tell when nobody edited them. It isn't one word that gives it away. It's a pattern: every sentence the same length, the same handful of phrases, and claims that never get specific.
The good news is that the fixes are mechanical. You don't need to rewrite from scratch. The twelve edits below, done roughly in this order, turn most drafts into something that reads like you wrote it.
1. Delete the first sentence
Model drafts almost always open by restating the topic or setting the scene: "In today's fast-paced world…", "Effective communication is more important than ever." Delete it and read the draft again. Nine times out of ten, the second sentence is a better opening.
2. Vary sentence length on purpose
The strongest signal of unedited AI text is rhythm. Generated sentences cluster around the same length, usually 18 to 25 words. People write in bursts: a long sentence that builds an idea, then a short one. Like this.
Go through the draft and break one long sentence into two, then join two medium ones. Aim for a mix of very short and long sentences in every paragraph.
3. Cut stock phrases
Certain words appear far more often in model output than in human writing: "delve", "tapestry", "seamless", "leverage", "unlock", "elevate", "robust", "it's important to note". None is wrong on its own, but a few in one paragraph is a tell. Replace each with the plain word you would say out loud, or cut it.

4. Remove stacked transitions
"Furthermore", "Moreover", "Additionally", "In addition" at the start of consecutive sentences is a strong pattern. Most of these can simply be deleted; the logic still flows. Keep a transition only where the relationship between ideas would otherwise be unclear.
5. Add one detail only you know
Generated text is generic because the model doesn't know your situation. The fastest way to make a draft yours is to add one specific: a number from your own work, a customer's actual words, the name of the tool you use, the date something happened. One concrete detail does more than ten adjectives.
6. Replace adjectives with facts
"Our powerful, intuitive platform" tells the reader nothing. "Our platform sets up in about ten minutes" does. Find every adjective that is doing persuasive work and ask what fact would prove it. Use the fact instead.
7. Commit to a position
Models hedge: "this may potentially help", "it can often be beneficial", "there are several factors to consider". Readers trust writers who say what they think. Remove one hedge per paragraph and state the claim directly. Keep hedges only where you genuinely aren't sure.
8. Break the rule of three
AI drafts love lists of three: "clear, concise, and compelling", "faster, cheaper, and better". When every list has exactly three items, it reads as a formula. Cut some to two, expand some to four, or turn one into a sentence.
9. Use contractions where the tone allows
Unedited model output often avoids contractions, which makes even casual writing sound stiff. In emails, posts and most business writing, "it's", "we're" and "don't" read more naturally than "it is", "we are" and "do not".
10. Kill the summary ending
Generated pieces end by summarizing what you just read: "In conclusion…", "Overall, by following these steps…". End instead with a next step, a recommendation, or a single strong line, and let the reader go.
11. Read it out loud
Anything you wouldn't say to a colleague, rewrite. Reading aloud catches stiff phrasing, awkward rhythm and words you'd never use faster than any tool.
12. Check it, then check the result
Run the draft through a checker that tells you which sentences read as generated and why, edit those, and check again. Plainspoke does this in one screen: it flags each sentence with a reason, rewrites the draft for the context you pick (a cold email, a LinkedIn post, a resume), and re-checks the result so you can see what changed.
A quick before and after
| Before (unedited AI) | After (edited) |
|---|---|
| In today's fast-paced digital landscape, it's important to note that effective email marketing can help businesses unlock unparalleled engagement and foster meaningful connections. | Email still beats most channels for small businesses, mostly because you own the list. The catch: people only open emails that sound like they came from someone. |
What not to do
Don't try to "trick" a reader with deliberate typos or random synonyms. Synonym-swapping tools often make writing worse and introduce errors. The goal is writing that is clear and specific, which is also writing that reads as human.
And be honest about where AI help is allowed. Many schools and some employers have rules about AI use; follow them. Plainspoke is built for professional writing, not for submitting work where AI assistance is prohibited.
Frequently asked questions
How do I make ChatGPT text sound less robotic?
Delete the opening sentence, vary sentence length, cut stock phrases like "delve" and "seamless", add one specific detail from your own experience, and end without a summary. Then read it out loud.
Is there a tool that makes AI writing sound human?
Several tools rewrite AI text. Plainspoke focuses on professional writing: it shows which sentences read as generated and why, rewrites for a chosen context, and re-checks the result.
Can I just ask ChatGPT to "sound more human"?
It helps a little, but models tend to trade one set of habits for another. Specific instructions (vary sentence length, no transitions, add this detail) and your own edits work better.
