Ghostwriting
AI LinkedIn ghostwriter vs a human ghostwriter: which is worth it?
An AI LinkedIn ghostwriter costs $39 to $99 a month; a human costs far more. Here's what each actually does well, and the AI tools that come closest to a good human ghostwriter.
Short answer
A good human ghostwriter interviews you, finds your stories and pushes back. The best AI ghostwriters copy that process: Supergrow interviews you by voice, Flypost drafts from your whole archive of blog posts, videos and documents, ContentIn learns from your past posts, and Oiti models a detailed persona. They cost $39 to $99 a month. Use a human when the stakes, and the budget, are high.
The best human LinkedIn ghostwriters don't write for you. They interview you, pull out the stories you'd never think to tell, and shape them into posts that sound like you on a good day. That's the bar an AI ghostwriter has to clear.
What a human ghostwriter does that AI struggles with
- Pushes back on a weak idea.
- Notices the story buried in an offhand comment.
- Knows your industry's politics and sensitivities.
- Takes responsibility for the post going out right.
What AI does better
- Volume and speed. A week of drafts in minutes.
- Memory. Everything you've ever written or said, searchable.
- Price. $39 to $99 a month for one person.
- Formats. Carousels, infographics and images, not just text.

A hybrid that works
Most people get the best results from AI drafts plus a human edit, even if that human is you. Let the tool produce a first draft from your real material, then spend five minutes adding one specific detail and cutting anything that sounds like AI. Posts that read as AI-written got about 24% fewer reactions in our study of 2,016 posts, so that edit is the most valuable five minutes of the process.
