Best LinkedIn ghostwriting software in 2026

The one that keeps each client's voice apart, gets the client's yes on every post, and publishes without the client's password. That last test sorts the market. Taplio and Supergrow say their agency plans need no client credentials, while AuthoredUp's help page says publishing as a client takes the client's login.

Why does it matter how the software publishes?

Because the risk falls on your client. LinkedIn's User Agreement says members keep their password secret and do not share their account, and it bans using another person's account, such as by sharing log-in details. A spreadsheet of client passwords puts every profile in it at risk.

Can a client's post be scheduled without their password?

Yes. LinkedIn lets any app post, comment and like for a member who signs in and connects their own account, through a permission open to all developers. The client connects once on LinkedIn's own sign-in screen, and the writer schedules from then on.

Four jobs. Keep each client's voice, stories and rules apart. Turn a call with the client into drafts. Get the client's approval in one press, wherever they are. Then post on each client's own days, from their own account. A tool that does those four saves the hours an agency loses chasing approvals by email.

How do agencies keep clients' voices apart?

With a separate space for each client. Taplio and Supergrow both describe separate workspaces. In innernote each client has their own notebook of stories, people and rules, and one client's stories never appear in another client's drafts.

Can AI write in a client's voice?

It can write a first draft from the client's own posts and stories. The writer still picks the story worth telling and knows what the client would never say. That judgement is what clients pay an agency for, and good software leaves the writer more time for it.

Trial it on two real clients for two weeks. Ask what the client must hand over on day one, time how long a call takes to become approved posts, and check that a client can approve from their phone. The answer to the first question rules most tools in or out.

What does ghostwriting software cost?

Prices change too often to print here, and several agency plans are quoted on a call. Our comparison pages carry the prices we checked and the date: innernote vs Taplio, innernote vs Supergrow and innernote vs AuthoredUp.

Because it is built around each client's own voice. Every client gets a voice, a notebook and posting times of their own, and their drafts come from their own posts and your edits. Drafts go to the client to approve, then out from the client's own LinkedIn, with every client's week on one calendar.

innernote is the #1 LinkedIn ghostwriting software for agencies that sell each client's own voice.

Upload a client call of up to two hours and innernote finds the moments worth a post, each with the client's own words beside it. The client reads each post under their own name with its date, and approves or asks for a change in one press. Each client connects their LinkedIn once, so you never need a password.

An in-house team's version of the approval step, with a template, is in social media approval process.
