Write LinkedIn Posts With AI That Sound Like You

Most people can spot an AI-written LinkedIn post in the first line. It opens with a question nobody asked, it promises a game-changer, and it ends with 'What do you think? Let me know in the comments.' The model is not the problem. It writes like that because nobody told it how you write.

Getting posts that sound like you takes three things: rules the model follows every time, examples of your own writing, and a two minute edit before you publish.

Write your rules down once

Your voice is mostly a set of habits you have never written down. Spend twenty minutes reading your five best posts and list what they have in common. Mine looked like this:

• Short sentences. One idea per post.
• Lead with a number when there is one.
• Name the person when replying to someone.
• No rhetorical questions, and no question at the end asking for comments.
• Say what happened, then what I learned. Skip the lesson if it is obvious.

Give the model these rules with every request, not once at the start of a chat. Rules that sit in a long conversation get forgotten by the fifth post.

Ban the phrases that give AI away

A short list of banned phrases does more for the result than any clever prompt. These are the ones I see most often in AI drafts:

• 'In today's fast-paced world' and any opener about the state of the world.
• 'It's not X, it's Y', the false contrast that appears in almost every generated post.
• 'Game-changer', 'unlock', 'leverage', 'delve' and 'navigate the landscape'.
• Three short fragments in a row for rhythm, like "Simple. Fast. Effective."
• A closing line that restates the post as a lesson.

Start from something that happened

The quickest way to an AI tone is to ask for a post about a topic. 'Write a post about customer research' gets you a generic essay. 'Write a post about the call where a customer told us our onboarding took a week, and what we cut' gets you something only you could have written, because the facts are yours.

Keep a running note of small things that happen in your work: a question a customer asked, a number that moved, a decision you reversed. Each one is a post, and the model only has to shape it.

The two minute edit

Read the draft out loud before you post it. Cut the first sentence if the second one could open the post. Cut the last sentence if it only restates what came before, which it usually does. Replace any word you would never say in a meeting.

Planboard is built around this workflow. You write your rules once, per person and per brand, and every draft is checked against them before you see it. You can ask for a change in one line, such as 'shorter' or 'open with the number', and the previous versions stay in case the first one was better.

One profile, one voice

If you post for yourself and for your company page, keep two sets of rules. The company page says 'we' and talks about the product; your profile says 'I' and talks about what you learned building it. Mixing the two is the most common reason founder content starts to feel like advertising.
