To get a LinkedIn post from Claude that sounds like you, give it three things: five or more of your own posts to copy the voice from, one real detail the post is about, and LinkedIn's format rules. Without them you get the generic AI post people scroll past; with them, and Postel connected, Claude can also schedule the post to your LinkedIn profile once you approve it.

Draft a LinkedIn post about what we shipped this week: CSV export and faster search. Three customers asked for them on calls.
Postelgenerate-postSaved as a draft
We shipped two small things this week, and both came from customer calls.
CSV export now works from any view. Search answers before you finish typing.
Three customers told us on calls where they lost time each week, so we fixed that first. If something feels slow to you, reply and tell me.

Done. It goes out Wednesday at 8:30 AM. You can still edit it in Postel until then.

An example chat, drawn by us with Postel's real tool names. Claude's own screens look a little different.
Your voice. Paste five to ten posts you wrote and liked. Claude copies sentence length, rhythm and word choice far better from examples than from a description like "conversational but professional".
One real detail. The number, the customer quote, the decision, the mistake. Claude can't know your week. If you don't give it a detail, it fills the gap with general advice or, worse, a made-up anecdote.
The format. LinkedIn shows about the first 210 characters before "see more", less on a phone, so the opening has to work alone. A post can be 3,000 characters long. LinkedIn has no bold or italics, and many people put links in the first comment rather than the post.
A prompt that works
Copy this, fill the brackets and paste your posts underneath:
Write a LinkedIn post in my voice. Match the posts below: their sentence length, how they open, and the words I use.What happened: [one specific thing, with the number or quote]Who it's for: [the reader, e.g. founders of small B2B SaaS]What I want them to take away: [one sentence]Rules:- The first line must make sense on its own; LinkedIn cuts the post after about 210 characters.- Short paragraphs, a blank line between them.- No hashtags, no emojis, no question at the end.- Don't add facts, numbers or stories I didn't give you.- 900 to 1,500 characters.My posts:[paste 5 to 10 of your posts]
Then edit with short follow-ups: "Cut the second paragraph", "Make the opening the result, not the setup", "Say it the way I'd say it to a friend".
Prompts for common LinkedIn posts
A lesson: "Write a post about what I learned from [event]. Open with what went wrong, then what I'd do differently. Keep my numbers exactly as I gave them."
A launch: "We shipped [feature]. Write a post for [reader] that starts with the problem it solves. Mention the feature name once. The link goes in the first comment."
An opinion: "I disagree with [common advice] because [your reason and example]. Write a post that says so plainly and gives the example. No hedging."
From notes: "Turn these meeting notes into one LinkedIn post about the most surprising point: [paste notes]."
Hiring: "Write a hiring post for [role]. Say what the person will actually do in the first 90 days and who they'd work with. No 'rockstar'."
Set it up once with a Claude Project
Instead of pasting your posts every time, create a Project for LinkedIn. Add your best posts and a short note on your audience to the project's knowledge, then put the rules from the prompt above in its instructions. Every chat in that project starts in your voice. Projects are on every Claude plan, including the free one.
What to cut from Claude's drafts
Even with good examples, a few habits slip through. Ask Claude to remove them, or cut them yourself:
an opening that sets the scene instead of saying the point
"Here's the thing", "Let that sink in", "This changed everything"
three-part lists where you'd naturally say one thing
a closing question added only to get comments
a lesson tacked on that the story already made
A quick test: read it out loud. If you wouldn't say a sentence that way to a colleague, rewrite it.
From Claude to LinkedIn without copy and paste
Copy and paste works. If you post every week, connect Postel instead: Claude saves the draft in Postel, and when you say "schedule it for Wednesday at 8:30am" Postel posts it to your personal LinkedIn profile at that time.
Two ways to write once it's connected:
Claude writes, Postel saves. Claude drafts in the chat from your project, and Postel saves the text as a draft (create-post, no AI credits).
Postel writes in your voice. Claude asks Postel to draft it (generate-post, 1 AI credit). Postel uses the voice profile it built from your own LinkedIn posts, so you don't need to paste samples.
Claude asks before it schedules or publishes, unless you've set those tools to always allow. Scheduling and publishing need a paid plan or the trial. Setup takes a few minutes: how to connect Claude to LinkedIn.
Write LinkedIn posts in your voice from Claude, and schedule them
Postel learns how you write, drafts posts in your voice and publishes them to X, LinkedIn, Bluesky and Mastodon on schedule. Use it on its own or from Claude, ChatGPT or Cursor.

Yes, when it has your posts to copy from and a real detail to write about. Without those, its posts read like everyone else's AI posts.
What's the best Claude prompt for a LinkedIn post?
One that includes your own posts as examples, a specific thing that happened, who the post is for and LinkedIn's format rules. The prompt above has all four.
Can Claude post to LinkedIn for me?
Not on its own. With a connector like Postel, Claude can schedule or publish the post to your personal LinkedIn profile after you approve it.
Claude or ChatGPT for LinkedIn posts?
Both can sound like you if you give them your own posts. The examples matter more than the model. If you use ChatGPT, see how to write LinkedIn posts with ChatGPT.
How long should a LinkedIn post be?
LinkedIn allows 3,000 characters. Most good posts land between about 900 and 2,000. What matters most is the first 210 characters, because that's all most people see before "see more".
Can Claude write a LinkedIn carousel?
It can write the slide text. To turn it into a PDF carousel and schedule it, use the LinkedIn carousel maker in Postel.
What does Postel cost?
$1 for 7 days, then from $29 a month. Cancel anytime. The Claude connector is included in every plan.
