How to Use AI for Social Posts Without Sounding Like AI

Using AI to draft posts is not the problem. The problem is the post that comes back when the model knows nothing about you: a confident, upbeat paragraph about “growth” and “success” that would fit any business on earth. Readers have seen thousands of them, and they recognise the pattern before they finish the first line.

A generated post gives itself away in three ways: stock phrases, sentence shapes that repeat, and vagueness — nothing in it that only you could have said. The first two you can fix by editing. The third you fix before the model writes a word.

Phrases to cut on sight

Some phrases turn up so often in generated text that they now read as a signature. None of them is wrong as English; they just tell the reader nobody chose these words. Here are most of the ones Postclo's own writing check looks for, grouped by kind:

Some single words get the same reaction when they are used loosely — leverage, robust, streamline, empower, foster, crucial, pivotal, landscape, journey, transformative, innovative, holistic, synergy. Each has an honest literal use (a journey is a trip; a landscape is land), so the test is whether you mean it literally. Usually there is a plainer word: use for leverage, strong for robust, important for crucial — or nothing at all.

Sentence shapes that give it away

• “It's not just X — it's Y.” The model's favourite way to sound profound. Say Y.
• The one-word reveal: “The result?”, “The best part?”, “The catch?” followed by the answer. Just give the answer.
• The announcement: “Here's why:”, “Here's what you need to know:”. Skip to the why.
• The connectives: “Moreover”, “Furthermore”, “Additionally” at the start of sentences. People posting don't write like that.
• The summary at the end: “In short…”, “Ultimately…”, “At the end of the day…”. If the post was clear, it doesn't need repeating.
• Three adjectives in a row, an em dash in every other sentence, and every paragraph ending on a one-line moral.
• Formatting tells: emoji as bullet points, a bold label on every line, a pile of hashtags at the end.

The real fix is specifics

Cutting phrases makes a post less obviously generated. It doesn't make it good. What makes a post sound like a person is detail that only someone in your position would know — and a model can't know that unless you tell it.

Compare two prompts. “Write a LinkedIn post about our new booking feature” gets you a paragraph about convenience and seamless experiences. “Write a LinkedIn post for salon owners. Our booking page now lets clients pick a stylist, not just a time. We built it because three salons told us clients kept booking with the wrong person and then cancelling. Plain, a bit dry, no hype” gets you something with an actual point.

What to give the model, every time:

• Who it's for, in their own terms: “salon owners with two to five chairs”, not “businesses”.
• The one point of this post, in a sentence.
• The facts it may use — what you offer, what changed, what you've seen. Tell it not to add any others.
• The words your customers use for their own problem, from emails and calls.
• How you sound: a few of your own past posts, or a line like “short sentences, dry humour, never exclamation marks”.
• What to leave out: no statistics you didn't give it, no customer stories, no first-person memories it would have to invent.

An editing pass that takes five minutes

1. 1Read it out loudAnything you wouldn't say to a customer across a table, rewrite in the words you would use.
2. 2Search for the phrases aboveDelete them. Most sentences read better without them and need no replacement.
3. 3Check the first lineWould it still make sense for a different business? If yes, it is too generic — replace it with your actual point.
4. 4Add one detail only you knowA name, a price, a step in your process, a question a customer asked last week.
5. 5Check every claimEach number and each story either happened, with a source you could show, or comes out.
6. 6Vary the rhythmIf every sentence is the same length and every paragraph ends with a punchline, break a few up.

Keep your voice on file

The quickest way to stop re-explaining yourself is to write down, once, who you are for, what you offer, what you can prove and how you sound — and give that to whatever writes your drafts. It is the same document a new employee would need before writing on your behalf.

That is how Postclo works: each project has an overview you can edit, with your offer, audience, proof and voice, and every post is written from it. Drafts are checked for the phrases on this page, for figures nothing backs and for unfinished placeholders before you see them, and the flagged sentences are rewritten. It still makes mistakes, which is why you read and edit every post before you publish it yourself. If an idea is what you're missing, start with what to post when you have nothing to post.
