How do you make AI writing sound human on LinkedIn?

Specifics. Not vocabulary, not sentence length, not punctuation. Writing reads as human when it contains things that could only have come from one person's actual week: a number, a name, a date, a price, a decision that could have gone the other way.

This is worth being blunt about, because almost every guide on this gets it backwards. They tell you to vary your sentence lengths and avoid certain words, which is advice about texture. Texture is not the problem. You can give a hollow paragraph beautiful rhythm and it stays hollow, because nothing in it happened to anybody.

A model can imitate how people write. It cannot know what happened to you on Tuesday.

That gap is the whole opportunity. Everything below is a way of closing it, and none of it involves finding better words for the words you already have.

Only partly, and not in the way most people try. Asking a model to sound more human, be conversational, or write like a real person is an instruction about style, and style was never the missing piece. You get the same empty paragraph in a looser register.

What does work is changing what you put in rather than how you ask. Compare these two prompts. The first is a topic: write a LinkedIn post about hiring. The second is an event: we hired a senior engineer in March, they left in July, the recruiter fee was eleven thousand, and the mistake was that I ignored two references who hesitated.

The second prompt produces a post that only you could publish, and it did not require a single instruction about tone. That is the entire trick, and it is why prompt libraries for sounding human tend to disappoint. They are optimising the wrong half of the input.

• Give it one event with a date, not a subject area.
• Include the number, even if it is unflattering. Especially then.
• Say what you believed before and what changed it.
• Name the thing you got wrong. Nothing reads as human faster.

For the purpose most people buy them for, no. A humaniser paraphrases: it swaps words for synonyms and reshuffles clauses until the text scores differently. It cannot add a fact that was never there, so it takes an empty paragraph and gives you a differently worded empty paragraph.

There is a second problem that is easy to miss until it embarrasses you. Aggressive paraphrasing degrades meaning. It reaches for a less common synonym because the common one looked suspicious, and now your post says something slightly different from what you meant, in a register you would never use. On a personal brand that costs more than the thing it fixed.

Cleaning is a different job and a legitimate one. Stripping hidden characters and normalising punctuation is worth doing before you publish anything, and the AI text cleaner does exactly that without touching your words. Just be clear about what that buys you: a tidier surface, not a better post.

Five minutes, five passes, in this order. Each one adds information or removes filler. None of them are about word choice, which is the part everybody spends their time on and the part that changes least.

1. 1.Delete the first paragraph. Drafts almost always warm up for a sentence or three before the post begins. The real opening is usually line four.
2. 2.Put one number in. If the draft has none, it is describing a category rather than an event, and no edit will fix that. Go back and find the event.
3. 3.Name someone or something. A person, a company, a tool, a city. Proper nouns are the cheapest specificity there is.
4. 4.Find the sentence that sounds slightly too blunt and keep it. That line is usually the only one that sounds like a person, and it is the one an editing pass instinctively softens.
5. 5.Cut the closing lesson. The paragraph that starts with the takeaway is the most generic in almost every draft, and readers resent being told what to conclude.

If the draft cannot survive step two, the problem is upstream and you are editing the wrong thing. Go back to the prompt and give it an event. We went into why that hollowness happens in the first place in why AI LinkedIn posts sound cringe.

Here is the same post before and after. Nothing in the second version came from better word choice. Every difference is information that was not in the first one, which is why the fix is never a thesaurus.

Hiring is one of the hardest parts of building a company. The right people can transform your business, while the wrong hire can set you back months. Over the years I have learned that culture fit matters just as much as technical skill. Here are three lessons that changed how I approach it.

Before

Read that again and notice what you cannot learn from it. Not the company, not the role, not when, not what it cost, and not whether the writer has actually hired anyone. It is advice-shaped, and any founder in any industry could have posted it.

We hired a senior engineer in March. They left in July. The recruiter fee was eleven thousand dollars and none of it comes back. Two of their references hesitated when I asked why they left the last role. I heard the hesitation, and I hired anyway, because we were three months behind and I wanted the problem to be over.

After

Same topic, same author, roughly the same length. The second one is readable because it costs the writer something to publish, and because there is only one person on LinkedIn who could have written it. It also contains no advice at all, which is usually a sign you are on the right track.

Everything above gets you to sounding human. Sounding like you is a further step, and it is the one that does not survive being done by hand every time, because it means re-explaining your own voice to a blank prompt on every single post.

Most people discover this around week three. The edit pass works, the posts are fine, and it is taking forty minutes each because you are rebuilding the same context from scratch. That is the point at which people quit, and it is a tooling problem rather than a discipline problem.

Which is the reason innernote exists. It learns how you actually write and keeps it, so a draft arrives already in your register and you are editing rather than rewriting. You still supply the event and the number, because nothing can invent those, but you stop paying the setup cost every time. There is a walkthrough on the product page.

If you want to test the difference honestly, start free, write next week's posts from your own week rather than from a topic, and compare them to the last three you published.
