I have written the same email to new clients eleven times this year: no, we should not start with the tool. We should start with the decision the tool is supposed to make faster.
Most "software problems" I am hired for are a decision nobody has owned yet. The software just makes the absence visible. Find the owner first. The tooling conversation takes twenty minutes after that.
Why it sounds more like you than a ghostwriter does
A ghostwriter knows you from a weekly call. Everything else they write is guesswork dressed up in your industry's vocabulary, which is why ghostwritten posts read like they could belong to anyone in your field.
PostAgent starts from what you have actually written: your own LinkedIn posts, your profile, a book or a guide if you have one, talks, notes. It learns your sentence length, your openers, the words you reach for and the ones you never use. Then it writes from your real material, so the examples in a post are yours, the opinions are ones you hold, and the stories happened.
Two more things a ghostwriter can't do, and neither can a prompt. This is not one prompt writing your post; it is a series of them, a desk rather than a draft. After every draft, a separate reviewer checks each claim against your material and the public record, corrects anything wrong and holds back anything it cannot vouch for, before you or anyone else sees it. No prompt prevents a model from inventing a detail; a system that assumes it will, and reads for it, is the only thing that catches it. And you grade posts with a thumbs up or down; it learns from every one, so it gets more like you over time instead of drifting.
And then there's the price
A good LinkedIn ghostwriter runs $1,500 to $3,000 a month, wants an hour of your time every week for interviews, and still needs you to approve every draft. Most of what you pay for is the interviewing. PostAgent skips it: it reads what you've already written and works from that.
| Human ghostwriter | PostAgent | |
|---|---|---|
| Price | $1,500 to $3,000 / month | $79 / month |
| Learns your voice from | Weekly interviews | Your own posts, profile, books, talks, notes |
| Your time | An hour a week, indefinitely | About fifteen minutes, once |
| First posts | One to two weeks | Minutes, before you answer a single question |
| Approvals | Every draft | None required. Grade a few posts once; it learns. Pause anytime. |
| Publishing | You, or them with your password | Direct, through LinkedIn's official connection. Never your password. |
| Made-up claims | Happens. You catch it or you don't. | Every post is checked by a separate reviewer; anything wrong is corrected, anything unverifiable is held back, before you see it. |
Not a prompt in a trench coat. A desk that works for you.
A prompt tool asks you to type an idea and hands back text. Here the work is on the other side: it starts from what you have already written, every post is checked before anyone sees it, and you decide how closely you want to watch.
Give it your work
Screenshots of your LinkedIn profile and a handful of your own posts, straight from a phone. It reads them once, keeps only your words, and writes the first three posts in your voice within minutes, before a single question. Books, guides, talks and notes can go in after. Grade the three with a thumb up or down; that is the whole calibration.
Every post goes through the desk
A writer drafts from your material. Then separate reviewers read every claim against that material and the public record, a verifier rules on anything disputed, and an editor makes the smallest correction and sends it back to be read again. A post the desk cannot vouch for is held, not published. That is the difference between this and a prompt, and it is why a post takes a few minutes instead of two seconds. The roles are listed below.
See the week's posts ahead of time
Before anything publishes, the coming posts land in your inbox, already written and already checked. Read them over coffee once a week, or whatever cadence suits you: a thumb up moves a post to the front, a thumb down pulls it and teaches the agent, and silence means they run as planned. Nothing waits on you, and nothing goes out that you did not have the chance to see.
It publishes on your schedule
Connect LinkedIn through LinkedIn's own sign-in (never a password), pick the days and times, and it runs. Pause any time. If a connection ever expires you get one email, the posts wait, and they go out when it is reconnected. Set it up once, in about fifteen minutes.
Between posts, it asks you one question
Every week or so you get an email with a single question about your work: what a client got wrong, what changed, what you argued about last week. Answer in a sentence from your phone, or skip it. It keeps writing either way, but the answers are where the posts only you could have written come from. A prompt waits to be fed. An agent comes back and asks.
What happens before a post publishes
Most AI content tools are one prompt in a trench coat: one model, one instruction, a post in two seconds. Generating is easy. Catching is the product. Here a post moves through a desk the way a newsroom's does, writer to editor to fact-checker to standards, each with one job, and every one of them works on the most capable model we can get, never a cheaper tier.
- The writer works from a brief built out of your own material: your posts, book, talks, uploads and answers. Never from a one-line description.
- The reviewer reads the draft the way a senior peer in your field would and checks every claim in it, against your material first and against the public record where the material cannot settle it.
- The second reviewer reads the same draft, briefed to disagree with the first.
- The outside reviewer is a different AI vendor entirely, reading the same draft, so a blind spot one model line shares with itself does not pass.
- The verifier rules on every disputed passage against the primary source. Only what it confirms counts.
- The editor makes the smallest correction that fixes it, and the post goes back to be read again. A post that still cannot be vouched for does not go out.
- The art director turns the finished post into an image concept before any image is made.
- The final pass strips the tells that give AI writing away.
The honest part: no prompt stops a model from inventing a plausible detail. In 2025 two major newspapers printed a summer reading list in which most of the books did not exist; a model had written it and nobody checked, because plausible text is the whole job of a bare model. Anyone who tells you their prompt prevents that is selling you the prompt. So this system assumes it will happen and is built to catch it before anything publishes. It catches errors; it does not promise zero. It is built for people whose readers can check the claim, where made-up is not embarrassing, it is fatal.
That is why a post takes a few minutes to arrive instead of two seconds. The time is the evidence the desk exists. We have not found another tool in this category that does a fraction of this work. When it's your name on the post, we think the minutes are worth it. Being wrong in front of your own audience is the one thing you cannot take back.
It won't read like AI. Your readers would notice.
LinkedIn is filling up with generated posts and your readers have learned the tells: the em dashes, the stock phrases, the cadence that sounds like everyone and no one. If your reputation is the business, a post that reads as AI-written is worse than no post. Nobody tells you. They just quietly discount you.
PostAgent is built against that. It works from a real corpus of your writing, carries your rhythm and your vocabulary rather than the model's defaults, and strips the tells on the way out. Read a draft next to something you wrote; it should be hard to tell where you stop and it begins.
One plan
- Writes and publishes LinkedIn posts on your schedule
- Voice modeled on your own posts, profile and material
- Images included
- A first comment with your link under every post, if you want one
- Output built to read like you, never like AI
- A separate claims check on every post, after it's written; anything wrong is corrected before you see it, anything it can't vouch for is held back
- Weekly preview by email; pull anything, or let it run
- Pause or cancel anytime
- 7-day free trial, no credit card required
- What if it's wrong? Every claim is checked after writing; anything the check cannot vouch for is held, never posted.
- Will it sound like me? It writes only from your own material, and you grade the first three posts.
- Can I stop it? Pause any time. The week's posts arrive by email before they publish.
Questions people ask
It's yours to the extent you give it material. Your own LinkedIn posts are the best sample there is; a few screenshots are enough to start. Books, talks and notes make it sharper. And you grade posts along the way, which it learns from.
You can pull any post before it goes out (it emails you the week ahead if you want that), pause the agent at any time, and grade the posts it wrote so the next ones move. And it never invents experiences or facts: a separate reviewer checks every claim after the draft is written, corrects what is wrong and holds back what it cannot vouch for, so what reaches you is already right.
No. You connect through LinkedIn's official sign-in and can disconnect from either side at any moment.
Consultants, advisors, attorneys, accountants, agency owners, engineers: people whose reputation is the business, who should be posting and aren't, and whose hourly rate makes writing posts by hand irrational.
