The short answer

The three are not three price points, they are three ways of reaching what you know. An AI tool can only recombine what has already been written down. A ghostwriter reaches what is in your head, by asking. An in house writer reaches what is in a colleague's head, by sitting near them. Decide by asking where the load bearing fact in your next ten posts actually lives, then pick the route that can reach it.

Three options, three different ways of reaching what you know

A ghostwriter, an AI tool and an in house writer are usually compared on price, turnaround and quality, which makes them look like three grades of the same product. They are not. Each one has a different reach into the material that makes a post worth reading, and that reach is fixed by how the route works rather than by how good the individual is. A brilliant model still cannot know what you decided in a meeting last Tuesday.

Disclosure, stated up front

Two of the options named on this page, Ra-Aha and Supersonify, are sister services run by the same team as this site. They are included because they fit two of the situations described, and each carries the same downside line as every other entry. No third party company is named anywhere on this page, since we cannot verify another firm's pricing, scope or quality, and pretending otherwise would make the comparison useless to you.

Read the three as capabilities rather than vendors and the choice gets much easier. An AI tool has fast, cheap access to everything already published, including everything you have already said. A ghostwriter working by interview has access to what is in your head and has not been said yet. An in house writer has access to the building, which is a different thing again, because most of what makes a post specific is currently sitting in somebody else's head two desks away.

51%

51% say text posts are what they most engage with. All three routes can produce a text post, so format is not the variable that separates them. What separates them is whether the text carries something the reader could not have got anywhere else.

The Source of Truth Test, which decides the choice in one question

Take your next ten posts, or the last ten if you have them. For each one, find the load bearing fact, meaning the single thing that would make a reader stop and think. Then ask where that fact lives. There are only five answers, and each one is reachable by a different route. This is the whole decision, compressed into one exercise that takes about twenty minutes.

The Source of Truth Test

Five places a load bearing fact can live. Count how many of your ten posts fall into each, then read the route that reaches it. The distribution is usually a surprise.

Already publicThe fact sits in your old posts, your website, a report anybody can download. An AI tool reaches this instantly and cheaply, and so does a competent freelance writer. If most of your ten land here, you have a formatting problem rather than a writing problem, and the cheapest tool on the market will solve it.

In your head, never said out loudThe judgement call you made and never explained, the reason you turned down a deal, the thing you would say in a private dinner and have never typed. Only extraction reaches this, meaning a person asking you questions on a schedule and recording the answers. No tool can retrieve what has never been recorded.

In a colleague's headThe objection sales hears every week, the support pattern nobody escalated, the engineer's opinion about why the obvious approach fails. An in house writer reaches this by sitting near it. An external writer reaches it only if you build them a route to those people, which almost nobody does.

In the company's dataUsage patterns, pipeline shapes, support volumes, retention curves. This requires access and permission, and it is the source most often promised and least often used, because giving an outside writer a data seat is a decision somebody has to sign. Whoever gets that seat produces posts nobody else can copy.

It does not exist yetThe fact requires a new observation, an experiment, a customer conversation you have not had. No route on this page can write it, and this is the honest answer for a founder who feels their posts are thin. The gap is upstream of the writing, and hiring anybody to solve it converts a research problem into an invoice.

The pattern in most executives' ten posts is that six sit in the first category, three in the second and one in the fifth. That distribution tells you something specific: the majority of what you publish could be produced by a tool, the minority that actually earns attention could not be produced by any tool, and the honest arrangement covers both rather than pretending the second category is bigger than it is.

What each route is structurally good and bad at

This table is about capability, not quality. A poor ghostwriter is worse than a good AI workflow, and a strong in house writer beats both. What the table describes is the ceiling and the floor of each route when it is executed competently, which is what you are choosing between before you meet anybody.

Capability	AI drafting tool	Freelance writer on your briefs	Interview led ghostwriter	In house writer
Reaches a fact only in your head	No, it can only recombine what exists in text	Only if you write the brief that contains it	Yes, this is the entire mechanism	Yes, over time and by proximity
Reaches a fact in a colleague's head	No	Rarely, and only if you arrange the introduction	Sometimes, if the retainer includes team interviews	Yes, this is the strongest advantage of the route
Reaches internal data	Only what you paste in	Only what you send	Only with a named access arrangement	Yes, subject to internal permission
Produces a competent first draft in ten minutes	Yes	No, it takes a brief and a turnaround	No, and it should not try	Sometimes, once the voice is learned
Tells you the argument is weak before it is published	No, it will improve the prose of a weak argument	Rarely, since the brief is the contract	Yes, if the arrangement is senior enough	Yes, and with more context than anybody external
Absorbs legal and factual risk	No, the risk is entirely yours	Partly, by contract	Partly, by contract and process	Yes, it sits inside your own approval chain
Survives one person leaving	Yes	Yes, at the cost of a new brief cycle	Depends on whether the voice file and transcripts are yours	No, this is the weakest point of the route
Cost of adding a second executive	Almost nothing	Roughly double	Less than double, since the process is built	Almost nothing, until capacity runs out

Structural capability, assuming each route is executed competently. Yes and no here describe what the route can reach, not how well any individual performs.

Two rows are worth reading twice. An AI tool will happily improve the prose of an argument that should not be published, which is the most expensive failure mode on the table, because polished wrongness travels further than clumsy wrongness. And an in house writer, the most costly option, is the only one that fails completely when one person resigns.

What to take away

An AI drafting tool has no access to anything that has not already been written down, which means it can restate your position beautifully and can never produce a fact that is new.
A ghostwriter's structural advantage is extraction, which is asking you a question you would not have asked yourself and capturing an answer that exists nowhere else.
An in house writer's structural advantage is proximity, since they hear the sales calls and the product arguments and can gather material without spending your hours.
On the assumptions worked through here, a full in house writing role is justified at around seven posts a week across the company, which usually means three or four executives rather than one.
The comparison that decides it is not price per post but which of the five sources of truth your next ten posts depend on, and only one of those sources is reachable by all three routes.

The six options side by side, ordered by who they actually fit

The list below covers the three routes in the title plus three adjacent ones, because the honest answer for a good number of readers is a fourth thing. The order runs from the option that fits the most readers of this page to the option that fits the fewest, which puts the cheapest first and the largest commitment last.

An AI drafting tool fed with your own raw material

A model turns your transcripts, voice notes and rough arguments into structured drafts, and acts as an editor for order and length. Used well it is a second draft machine, not a first thought machine.

Best forAnybody who already has opinions on record and wants speed, especially one person publishing once or twice a week with no budget line for writing.

Costs youThe smallest money on this page by a wide margin, and roughly 25 minutes of your attention per post spent prompting, correcting and checking claims. That attention is not optional and is where the route quietly fails.

Watch outIt cannot produce a first hand fact, and it will phrase a weak argument confidently. Assume two load bearing claims per post and you are personally responsible for verifying more than two hundred of them a year.

An interview led ghostwriting retainer

A recurring interview pulls material out of your head, transcripts store it, and posts are built from things you said rather than things you already published. You are buying the questions and the discipline that surrounds them.

Best forExecutives whose best material only appears in conversation, who talk more clearly than they write, and who will reliably attend a call every fortnight.

Costs youThe highest ongoing fee among the individual routes, plus roughly 45 minutes a fortnight of interview time and a few minutes of review per post. Published price ranges for this work disagree with one another and none state scope, so treat any figure you find as one seller's packaging.

Watch outIt depends entirely on your attendance, and when you start skipping interviews the drafts quietly revert to rewriting your archive. That decay takes about six weeks to become visible and is usually blamed on the writer.

A freelance writer working from your briefs

You supply the angle and the facts, somebody else turns them into finished posts. The thinking stays with you and you are buying execution hours against a brief you wrote.

Best forPeople who know exactly what they want to say and have no time to type it, and who can produce a useful brief in five minutes rather than thirty.

Costs youUsually the cheapest paid human option per post, plus about twenty minutes of your time per post in briefing and review. The hidden cost is that a thin brief still costs full price.

Watch outThe output is capped by your brief, and the writer has neither the mandate nor the context to tell you the angle is weak, so a bad month of thinking produces a bad month of well written posts.

Ra-Aha, positioning and profile advisory for individuals sister service

Advisory work on one person's positioning, headline, About section and profile, so that what you are known for is decided before anybody writes at volume. Diagnosis and repair rather than weekly output.

Best forThe executive who cannot yet name their reader in a job title, or whose posts get read while the profile behind them gives nobody a reason to act.

Costs youA bounded engagement rather than a monthly fee, and real attention from you while it runs. Small next to a year of production, and entirely wasted if production was the actual constraint.

Watch outIt produces no posts at all. If your positioning is already sharp and your problem is that Thursday keeps arriving without a draft, this fixes nothing you were worried about.

An in house writer on payroll

Somebody employed by you writes the executive's posts alongside other content work, close enough to sales calls and product decisions to gather material without booking your time.

Best forCompanies with several executives publishing, plus a company page, a newsletter and customer stories that need the same person.

Costs youA full salary, of which one executive's posting consumes a fraction, plus about an hour a week of your management time and the hiring time in year one.

Watch outEverything stops when that person is on leave or resigns, and the voice knowledge they built lives in their head rather than in a file, so the replacement starts at zero.

Supersonify, LinkedIn run as a company growth channel sister service

LinkedIn handled at company and team level: the company page, paid campaigns, employee advocacy and reporting that connects activity to pipeline. Individual posting becomes one input rather than the whole programme.

Best forA marketing lead with a budget and a board asking what the channel returned, where one person's posts are no longer the limiting factor.

Costs youA programme fee plus media spend, and a named internal owner who can actually make decisions. The heaviest commitment on this page in both money and coordination.

Watch outIt is the wrong purchase for a single executive who wants better writing. You would be buying campaign and reporting infrastructure to solve a problem that lives in one person's calendar.

If you read that list and conclude that a tool plus your own transcripts is enough for now, that is a correct conclusion for a large share of readers, and the arithmetic behind it holds up in what a ghostwriter actually costs. The routes further down the list buy reach into material the earlier ones cannot touch, and nothing else.

The volume threshold that makes an in house writer rational

An in house writer is either the best value on this page or the worst, and the line between the two is volume. The arithmetic below states its assumptions out loud so you can replace them with your own, and it produces a threshold rather than a recommendation.

Assume a post that carries a real argument takes three and a half hours of a writer's time, covering research, an interview, a draft and an edit.
Assume a full role delivers about 1,600 productive hours a year, which is forty working weeks at forty hours with the rest lost to meetings, leave and admin.
At two posts a week, or 104 a year, the executive's LinkedIn consumes 364 hours, which is roughly 23% of that role.
To occupy 80% of the role, or 1,280 hours, you would need about 366 posts a year, which is seven a week across the company.
Seven posts a week is rarely one person. It is three or four executives publishing twice a week, or two executives plus a company page and a newsletter.

So the threshold is not company size or revenue. It is roughly seven pieces a week of work that only an internal person can do. Below that, you are buying a full role to use a quarter of it, which is defensible only if the other three quarters have real work waiting. Above it, an in house writer is cheaper than any external arrangement and reaches material no external writer can get near, because they are in the room where it happens.

The failure this arithmetic predicts

Companies routinely hire one content person to run an executive's LinkedIn, then fill the remaining three quarters of the role with unrelated marketing work. Within two quarters the unrelated work has expanded, the posting has become the thing that slips, and the conclusion drawn is that LinkedIn did not work. The role design failed, not the channel.

What each route does to your risk, which nobody prices

Risk moves between the three routes rather than disappearing. Knowing which risk you have taken on is more useful than trying to avoid all of them, since every arrangement carries at least one.

Route	The risk you take on	The mechanism that reduces it
AI drafting tool	Publishing a confident claim that is not true, and sounding like everybody else who uses the same tool	A verification step you actually perform, and feeding it new raw material weekly rather than your own archive
Freelance writer on briefs	Drift toward generic writing during weeks when your briefs are thin	A standing rule that a thin brief becomes a five minute call rather than a guessed draft
Interview led ghostwriter	Total dependence on your own attendance, plus concentration of your voice knowledge in one external head	Contractual ownership of the transcripts and the voice file, checked before signing rather than at the exit
In house writer	Single point of failure, and a role designed around a task that cannot fill it	Written voice documentation held by the company, and a role scoped to seven pieces a week of internal work
Positioning advisory	Paying for clarity you then fail to act on, which leaves you with a document and no posts	A defined production plan attached to the end of the engagement, agreed before it starts
Company channel programme	Buying coordination and reporting for a problem that was one person's calendar	An honest diagnosis of whether the constraint is the individual or the channel, before any spend is committed

The risk each route hands you, and the mechanism that reduces it. None of these are eliminated by paying more.

The risk most often ignored is the third one. Executives sign arrangements where the voice file, the interview recordings and the idea queue belong to the provider, then discover at the exit that eighteen months of accumulated understanding walked out with the invoice. That is a contract question rather than a quality question, and it is settled in the same conversation as paying per post or per month.

A four week test you can run before choosing any of them

You do not need a year to answer this. Four weeks and eight posts will tell you which route your material actually requires, at almost no cost, and the exercise leaves you with usable posts either way.

Week one, record instead of writing

Take a twenty minute call with a colleague about a decision you made recently, and record it with their agreement. Do not write anything. You are testing whether your material appears in conversation, which is the single strongest signal for or against an interview led route.

Week two, run the transcript through a tool

Feed the transcript to an AI drafting tool and produce two posts. Judge them on one question only: does either contain a fact that was not already public? If yes, your material is reachable by tools plus your own recordings, and you can stop shopping.

Week three, write two posts from a cold start

No transcript, no tool, just you and a blank page for both posts. Time it honestly, including the staring. This is your real baseline, and it is almost always higher than the number people quote when they say writing takes them twenty minutes.

Week four, ask a colleague for the material you cannot see

Ask somebody in sales or support for the objection they answered most often this month. Write one post from it. If that post is the best of the eight, your constraint is proximity, and proximity is what an in house writer buys.

Score the eight and read the pattern

Sort the posts by which of the five sources of truth they came from. Whichever source produced your best two posts is the source your arrangement has to reach, and every route on this page is now judged on one criterion instead of five.

Most people who run that test discover something uncomfortable and useful, which is that their best post came from a twenty minute conversation they would never have booked. That finding points at a process rather than a purchase, and a process is cheaper. When you do go shopping, take the questions that reveal a real process with you and the shortlist sorts itself in a single call.

Questions people ask next

Can an AI tool learn my voice well enough to replace a writer?

It can imitate your sentence patterns closely, and that is not the constraint. The constraint is access: a model can only recombine text that already exists, so it can restate your known positions and cannot produce a judgement you have never recorded. Feed it new transcripts weekly and the gap narrows considerably.

Is it cheaper to have my assistant write my posts?

Rarely, and the reason is structural rather than about ability. An assistant has proximity to your calendar but not to your reasoning, so they can reliably produce announcements and struggle with arguments. It works when the assistant sits in the meetings and can ask you three questions afterwards without booking time.

What happens if I use both a ghostwriter and an AI tool?

That is the most common working arrangement and it is sensible when the division is clear. Use the interview and the writer for posts carrying an argument, and the tool for reactive posts and repurposing. The failure mode is splitting one post across both, which produces a draft nobody owns.

How do I tell whether my in house writer is underused?

Count the pieces a week that only somebody internal could produce. If that number is well under seven, the role is not filled by this work and the remainder is being filled by something else, which will gradually take priority. Check what actually shipped last month against what the role was hired for.

Does an external writer ever beat an in house one on quality?

Yes, in two situations. When the external writer has more range from working across many executives and can see that your best story is the one you find boring. And when internal politics make it hard for an employee to tell a founder that an argument is weak, which is a real and underrated advantage of distance.

Which route should I choose if I only post during funding or launches?

None of the ongoing ones. Two or three intense pieces a year is project work, priced per piece, and a monthly retainer against a quarterly need turns into a subscription you resent. Buy the writing when the event exists and keep the transcripts, so the next piece starts from material rather than from nothing.
