How to use it
- Write what happened, or the news, with the details that make it yours: how many customer calls, what changed, what you’d do differently. The model only uses what you give it.
- Add the one thing readers should take away. It keeps the post from wandering.
- Pick a format (a story with a lesson, a list of lessons, an announcement, an opinion or a how-to) and a length.
- Rewrite the first line in your own words and cut any sentence you wouldn’t say to a colleague.
LinkedIn’s rules for posts
| What | Rule | Source |
|---|---|---|
| Post length | 3,000 characters | LinkedIn Help: Post and share updates |
| Longer pieces | Over 3,000 characters, LinkedIn points you to articles instead | LinkedIn Help: Post and share updates |
| Automation | LinkedIn may limit the visibility of posts it detects as inauthentic or made with an automation tool | LinkedIn Help: Post and share updates |
Checked against each platform’s own help and developer pages in October 2026.
Every draft here is checked against the 3,000-character limit and cut at a paragraph or sentence if it runs over. Nothing is posted for you.
What makes a LinkedIn post readable
- A first line that stands alone. The feed shows the opening lines and hides the rest behind “see more”. Put the specific thing first: “We dropped our free plan after 40 customer calls”, not “Some reflections on pricing”.
- Short paragraphs with space between them, but not every sentence on its own line, which reads like a list of slogans.
- Plain text. LinkedIn doesn’t render Markdown, so asterisks show up as asterisks. The generator strips them.
- One question at the end, if you want replies, that people can answer from their own experience.
Honest limits
The model writes from your input and is told not to invent numbers, customers or results; we also flag sentences that may state something you didn’t tell us. It doesn’t know your network or what has worked for you before. For your profile rather than a post, the LinkedIn headline generator writes the line under your name.
