How to Make AI Writing Sound Human, Like You Wrote It

Why does AI-drafted copy sound like nobody wrote it?

AI-drafted copy sounds like nobody wrote it because the model has no life to draw from. It picks the most likely words, so you get the safe middle of everything it has read. That middle is smooth and polite. It is also empty, and readers feel it within a paragraph or two.

Wikipedia editors keep a public field guide to these habits, called Signs of AI writing. It lists stock words, lists of three, puffed up claims about how important something is and vague phrases like "experts say" with no expert named. It is worth an hour of your time even if you never buy anything.

Here is what those habits cost you:

• Clients notice. A client who reads "In today's digital landscape" stops trusting the rest of the page.
• Your voice disappears. Every draft sounds like the same polite stranger, so readers have no reason to follow you.
• Editing takes longer than writing. You fix one phrase and the next draft brings it back.
• Readers stop at the first line. A flat opening loses people before they reach your point.

I am not immune either. When I audited my own site files on 2026-09-25, three of them carried 23, 28 and 26 em dashes. I had read those files more than once and never seen it.

There is also a search angle. Google says in its guidance on AI-generated content that it rewards helpful content however it was made. So the goal is not to hide that you used AI. The goal is text a reader is glad they read.

How to humanize an AI draft by hand, step by step

Humanizing an AI draft by hand means editing it in four passes, each looking for one kind of problem. Doing one pass at a time is faster than fixing everything in one read, because each pass needs a different kind of attention. You can do all of this today with a text editor.

1. Run the draft through a checker first. Paste it into our free AI writing checker. It flags stock phrases, em dashes, lists of three and flat rhythm, and shows where each one sits. It does not judge whether a robot wrote the text. It shows you what to fix.
2. Cut stock phrases and filler. Delete words like "delve", "seamless", "moreover" and "it is worth noting". Then reread the sentence. If it still works without the phrase, the phrase was filler. If it falls apart, the sentence had no point and needs rewriting.
3. Break up the lists of three. AI loves "fast, simple and powerful". Pick the one word that is most true and drop the others. Two items read like a choice. Three in every paragraph read like a template.
4. Fix the rhythm. Read the draft out loud. If every sentence is about the same length, it will sound like a metronome. Cut one sentence down to four words. Let another one run on a bit. Real people write unevenly.
5. Swap vague claims for facts. "Many users love it" says nothing. "Three of my last five clients asked for this" says a lot. If you do not have a real number, cut the claim instead of making one up.
6. Add one line only you could write. This could be a date, a mistake you made or an opinion that costs you something. It is the slowest step and the one that turns a draft into your writing.
7. Check your facts last. Rewrites can change a number or a name by accident. Compare the final draft with the original and confirm every figure is still right.

If you want examples of each tell, I wrote up seven AI writing tells editors catch. For a real job done this way, see how I rewrote 19 product descriptions in 2 days using the same passes.

One last note. Google's page on creating helpful, people-first content says large amounts of AI text published without review count as little to no effort. Editing is the review. Do not skip it.

Plain swaps for the words AI drafts overuse

The quickest win in pass two is a swap list. When you see one of these words, use the plain word or rewrite the sentence. This short list is taken from the word blacklist in the Humanizer Pro skill file, so it is the same list the tool works from.

Watch the small verbs too. The Wikipedia guide calls this "avoidance of basic copulatives". AI writes "serves as" or "stands as" where a person writes "is". Change them back. Plain "is" and "has" sound like a person.

The faster way: let Humanizer Pro run the editing passes

The faster way is to let Claude Code run the same passes with skills that already know the phrase list and the order of the edit. A skill is a saved set of instructions Claude Code loads when a task matches it, like a checklist it pulls out at the right time. Humanizer Pro is three of those checklists for writing.

The point of a written list is that a tool can follow it and you can check it. The humanizer's worked examples come from product reviews, but its rules apply to any prose.

How to use it, step by step

1. Buy and download. Gumroad sends the files right after payment.
2. Install the skills. Copy the three folders inside skills into ~/.claude/skills. There is no setup step. Ignore the git clone line in skills/humanizer/README.md: it installs the open-source upstream skill, not this version.
3. Run the humanizer. In Claude Code, type /humanizer and paste your draft. A plain request such as "Please humanize this text" also works.
4. Add your voice if you want a closer match. Type /humanizer, then VOICE SAMPLE: with 200 or more words of your own writing, then CONTENT TO REWRITE: with the draft. The skill looks at your sentence length, openers, vocabulary and quirks.
5. Review the highlighted changes. Read each change and the note on why it was made. Keep the good ones and undo any that changed your meaning.
6. Finish with the copy editor. Run /copy-editing for a last pass on clarity and flow, or /copywriting with a line on the audience and goal if the piece needs to sell.

What the output looks like

You get three things: a list of detected issues with a severity rating, the rewritten version with changes highlighted, and notes on what was changed and why. Stock phrases are gone, lists are trimmed, sentence lengths vary and the text leans toward your own way of writing. Facts, names and numbers are meant to stay as they were.

Here is a real pass, with one caveat: it was the humanizer skill I use on my own books, not a timed Humanizer Pro run. On a book draft in September 2026, the review found that seven chapters opened with the same "Now the..." pattern, so all seven openers were rewritten. The phrase "Read this again" appeared four times and was cut to one. On another long draft in October 2026, a reviewer told to hunt for AI writing first scored it 6 out of 10. The humanizer pass that followed made 104 corrections. I still read every change myself.

How much time it saves

I have not timed a hand edit or a Humanizer Pro run on the same draft, so I will not give you a ratio. The time I logged on my own book passes includes research and drafting, so it would mislead you as an editing number. What the pack takes off your plate is the hunt for stock phrases. You still spend time on the line only you could write.

The bigger win is consistency. Your tenth post gets the same careful edit as your first, even on a tired Friday. You still read every change, because no tool knows your readers the way you do.
