What does LinkedIn's Enhance Post button actually do?

It's LinkedIn's built-in AI writing assistant (previously branded 'Write with AI'). It rewrites your draft to be more polished — but it applies the same style to everyone, which is why studies keep finding that a large share of long LinkedIn posts now read as AI-written.

Why do enhanced posts sound like AI?

One-click rewrites optimize for polish, not voice. They add the classic tells: em dashes, words like 'delve' and 'transformative', forced three-item lists, and 'it's not just X, it's Y' constructions. Refining with a specific goal and then removing those tells avoids the pattern.

Is this free? Does it need LinkedIn Premium?

The Refine Content and Humanize AI Text tools are free with no signup — no LinkedIn Premium required. They're daily-capped to stay free.

Can it make my post bold or formatted for LinkedIn?

Formatting is a separate step: after refining, use the LinkedIn Text Formatter to add Unicode bold, italics, and bullet points, since LinkedIn has no rich-text editor.

LinkedIn 'Enhance Post' Alternative — Rewrite Without the AI Slop

A free alternative to LinkedIn's Enhance Post button: refine your draft with real control over tone and length, then strip the AI tells so it still sounds like you.

Direct answer

LinkedIn's Enhance Post button (formerly 'Write with AI') rewrites your draft in one generic pass, which is why enhanced posts tend to sound alike. A better workflow is to refine the draft with a specific goal — shorten it, change the tone, or fix the grammar — then remove AI writing tells like em dashes, 'delve', and forced triplets, and finally add one detail only you would know. You get an improved post that still reads like a person wrote it.

When to use this

You tried LinkedIn's Enhance Post button and the result sounded like every other AI post in the feed.
Your draft is good but too long, too stiff, or too casual for the audience you want.
You want AI help with a post without your readers noticing AI helped.

Steps

Paste your LinkedIn draft into the Refine Content tool.
Pick one refinement with a clear goal: Shorten for a rambling draft, Change tone → professional or confident for a stiff or flat one, Fix grammar for a near-final one.
Review the result and click 'Refine again' if you want to stack a second pass.
Run the result through Humanize AI Text to remove em dashes, AI vocabulary, and other tells.
Add one specific number, name, or personal detail the AI could not know, then post.

Before

Thrilled to announce that I've been delving into the transformative world of AI tools! It's not just about technology — it's about unlocking unprecedented opportunities, streamlining workflows, and driving meaningful outcomes. The landscape is evolving rapidly!

After

I spent the last month testing AI tools on real client work. Two of them saved me about four hours a week. One of them made everything worse. Here's what actually held up:

Common mistakes

Don't run a whole-post 'make it better' rewrite with no goal — that's exactly what makes Enhance Post output generic.
Don't publish the refined text without adding something specific to you; readers spot template posts instantly.
Don't style your hook with Unicode bold unless it's short — it isn't searchable and screen-readers struggle with it.
