Compare · A human ghostwriter

The LinkedIn ghostwriter alternative you never brief.

A LinkedIn ghostwriter interviews you, writes posts published as you, and bills a monthly retainer: $500 to $10,000 a month across three public guides read on 22 September 2026, with most founders paying $2,000 to $5,000. Sonar is the alternative for a founder whose week already holds the material. It reads your calendar, meetings, Slack and notes read-only, drafts LinkedIn and X posts in a voice measured from your own published posts, and publishes only what you approve, for $99 a month.

What a LinkedIn ghostwriter does

A LinkedIn ghostwriter writes the posts that go out under your name. The good ones run a process. An onboarding session captures your positioning and your stories. Then a recurring interview call, or a voice note you record, gives the writer raw material each week. Then drafts, then your review on each one, with one or two revision rounds built into most packages. The first month is usually onboarding and voice development, and the guides recommend budgeting for at least three months so the calibration has time to land.

After that comes a rhythm: 8 to 12 posts a month at the entry tiers, 12 to 16 in the middle, 16 to 20 or more at the top. Some retainers add engagement work on your behalf, profile optimisation, a content calendar and monthly reporting.

Hold one fact through the rest of this page. The writer's source is you, on a call. Whatever the retainer, what reaches the draft is what you remembered to say in that hour, and the writer's read of it.

What a LinkedIn ghostwriter costs in 2026

Three public pricing guides, each read on 22 September 2026. Each was published by a business that sells in this market, so the tiers are how sellers describe themselves; the ranges agree with one another, which is why they are worth printing. The landing page's comparison band cites the first of them.

Published 2 February, 21 May and 31 May 2026 respectively; figures as each page printed them on 22 September 2026. Windmill Growth adds that most founders and executives pay between $2,000 and $5,000 a month. Mylance puts a mid-tier retainer at $24,000 to $60,000 a year.

Four things move the number: how many posts a month, how much interviewing and research the writer does, whether engagement and profile work are in scope, and the seniority of the person writing. A per-post price looks cheaper until you multiply it by three posts a week for a year.

The retainer in a founder's terms

A mid-tier retainer at $3,000 a month for 12 posts is $250 a post and $36,000 a year. On the same guides' own process, it also costs an onboarding session, a recurring interview or voice note, and review time on every draft, so the writing hour moves rather than disappears.

What the retainer buys, and what it cannot

What it buys

  • A writer's craft: hooks, structure, the cut that makes a rambling story land. This is real, and it is what you are paying for.
  • A second mind on positioning. A good ghostwriter tells you which of your stories matter and which are only interesting to you.
  • Someone else holding the calendar. The posts go out because a person is paid to make them go out.
  • Revision rounds, usually one or two per post, and a voice document built over the first month.

What it cannot buy

They were not in your meetings. A briefing call is their source. The Tuesday call where a client's COO said the one line that would have made the post, the Thursday Slack thread where the team split down the middle, the number you finally saw on Friday: those reach the writer only if you carried them to the interview, a week later, in the order you happened to remember them. Most of a founder's best material never makes that trip.

The voice is theirs, written as you. A skilled writer gets close, and the calibration month exists because close takes work. Readers who know you will still sometimes hear the seam, and you will read every draft with that ear.

Your time does not go to zero. The guides above describe an onboarding session, then a recurring interview or voice note so the writer has raw material, plus review time on every draft. The writing hour becomes a talking hour and a reading hour.

When a human ghostwriter is the right call

Honestly, often. Four cases where the retainer is the right money and Sonar is the wrong tool.

  • A book. A manuscript is a different craft from a post, and it takes months of sitting with someone. Sonar does not write books. Hire the writer who has finished one.
  • A keynote or a bylined essay. A 2,000-word argument for a named publication, or a talk with a room to hold, wants a writer who can spend hours with you on one piece. The agency guides price a ghostwritten long-form essay at $1,500 to $4,000 on its own. Sonar drafts posts, researched when you ask, and a post is where it stops.
  • An executive with no time to approve. Sonar publishes only what you schedule, so if you cannot give the drafts a read each week, nothing goes out. A ghostwriter with posting authority keeps the feed alive without you. Say that plainly to yourself before choosing it: it is a decision about whose words go under your name unread.
  • A voice that does not exist in writing yet. Sonar measures your voice from posts you have already published, and the profile is strongest when there are posts to measure. If you have never written in public, a writer can help you find the register first.

Some founders keep both: a writer for the long pieces and Sonar for the week. Nothing on this page argues against that.

What Sonar does instead

Sonar's source is the week itself. You connect the rooms where the work happens once, read-only: Google Calendar, Google Meet, Slack, Granola, Fireflies, Wispr Flow, Notion and Zoom. About once a week Sonar reads the last seven days, pulls out the moments worth saying, a decision, a win, a lesson, a number, and discards the raw text. Each source's row in Settings shows a receipt of what was read.

  • The voice is measured, then held. From your published posts Sonar measures average sentence length, the share of sentences under eight words, paragraph length and how often you ask a question, and holds every draft to those numbers. LinkedIn and X each get a register from the same identity. The AI vocabulary and the LinkedIn cliches are banned outright.
  • It learns from your edits. Every change you make before posting is compared with the draft. Repeated patterns become standing voice rules, and you can mute any rule in Settings.
  • Five drafts a week, written before you arrive. Every week Home deals a deck of five: two from your moments, one from a story you told Sonar, one from a development in your niche, one from a pillar you chose. Keep a card and it lands on your board as a draft.
  • You approve every one. Open the draft, change what you want with one-tap refinements to tone, length, hook or structure, then schedule it or copy it. Only a post you scheduled is published, to LinkedIn and X.
  • Private people never reach a draft. A colleague, a client or a meeting participant is written as a role, "a client's COO", "someone on my team". The rule is in the instructions every draft is produced under.

One plan: $99 a month or $990 a year, every feature on, 7 days free. How it works walks one invented week end to end; the integrations page lists every source and what each one reads.

The verdict

Two lists. Whichever describes you is the answer.

Pick

A human ghostwriter

  • You need a book, a keynote or a bylined essay, and posts are the smaller part of the brief.
  • You will not read drafts, this month or next, and you want the feed alive anyway.
  • You want a person to argue with about positioning, on a call, every week.
  • You have never written in public and want help finding the register before any software measures it.

Pick

Sonar

  • Your week is full of meetings and the material you keep meaning to post about is in them.
  • You will give the drafts a read each week and approve the ones that are true.
  • You want the voice measured from your own published posts rather than calibrated over a month of calls.
  • You want LinkedIn and X from the same week, in a register each.
  • $99 a month is the budget, and $2,000 to $5,000 is a hire you would rather make somewhere else.
