Key takeaways
ContentIn is a LinkedIn AI ghostwriter that learns your voice from your profile and past posts, then drafts next week's posts every Sunday from your own material.
Pricing: Growth at $39 a month ($31 billed yearly) and Pro at $59 ($48 yearly), plus a custom Ghostwriter or Agency tier. There is no free plan: a 7-day trial that asks for a card, and a 30-day refund on your first payment.
Growth now includes unlimited AI drafts (it used to cap at 12 a month), two planned posts a week, 50 ideas, 4 carousels and 20 AI images a month.
Pro adds company pages, a third planned post a week, unlimited ideas and carousels, a Telegram bot, leads analytics and an MCP server for AI assistants.
Its claims that drafts become "indistinguishable" from your writing are its own. Its Capterra rating was 4.7 out of 5 from 82 reviews when we checked in August 2026.
If you also post on Twitter, or want a check on every draft, compare it with VoiceMoat, the Personal Brand OS for LinkedIn and Twitter: $1 for 3 days, plans from $35 a month. Disclosure: VoiceMoat is our product.
How we researched this. Everything below comes from ContentIn’s own pricing page and FAQ, read on 12 October 2026, plus its Capterra listing from our August research. We have not used the product ourselves, so there is no hands-on testing in this review. Disclosure: VoiceMoat is our product.
What is ContentIn?
ContentIn is a LinkedIn AI ghostwriter at contentin.io. You hand it your profile URL, it reads your profile and past posts, and it builds a voice model from your sentence length, vocabulary and the way you open a post. Every Sunday it drafts next week’s posts from your own material, asks you one question per post, and schedules them. Each edit and each published post feeds back in, which is how it says it “gets sharper every week”.
ContentIn’s homepage, captured 21 October 2026 from contentin.io. You start by pasting your LinkedIn profile URL.
It is aimed squarely at founders, coaches and consultants who want LinkedIn to generate leads but do not want to hire a ghostwriter, and it prices itself against one: about $2,000 a month for a human versus $39 for the software.
What changed in 2026
Unlimited drafts on Growth. The entry plan used to cap AI drafts at 12 a month; it now includes unlimited drafts.
A weekly drafted plan: two planned posts a week on Growth, three on Pro, drafted every Sunday.
A LinkedIn MCP server on Pro, so you can work from an AI assistant’s chat.
A pricing page of its own, with an FAQ that states the trial and refund terms plainly.
Who ContentIn is for
ContentIn fits a LinkedIn-only founder or consultant who wants a steady weekly rhythm with little effort, and who would otherwise consider a human ghostwriter. It is a weaker fit if you post on Twitter too, if you want to try it without a card, or if you want a visible read of how closely each draft matches your voice. To see how it compares with Kleo, Oiti and the rest of the LinkedIn stack, read the best AI tools for LinkedIn personal branding in 2026.
How ContentIn captures your voice
ContentIn trains on your profile and past posts, lets you fine-tune on your best posts, and lets you upload documents so it knows your stories, offers and audience. It says most users change less than 10% of a draft and that by week eight the drafts are indistinguishable from your own writing. Those are its own claims, not independent tests, and like most tools here it shows no per-draft voice check.

Reviews praised the interface and templates and criticised surface-level analytics and output that still needs editing.
Strengths and limitations
Where ContentIn is strong
A weekly rhythm with little effort: drafts arrive every Sunday.
Unlimited drafts on the $39 plan.
Company pages, a Telegram bot and an MCP server on Pro.
A real, count-backed rating on Capterra.
Where ContentIn is thin
LinkedIn only.
No free plan; the trial needs a card.
No per-draft voice check; the “indistinguishable” claim is its own.
Company pages and leads analytics only on Pro.
ContentIn vs VoiceMoat, and alternatives
VoiceMoat is the Personal Brand OS for LinkedIn and Twitter. audenAI, the AI inside it, learns how you write from your own posts, then helps you write, schedule, engage, analyse and grow, with Style and Stance checks on your drafts so posts read like you. Try it for $1 for 3 days. Plans from $35 a month. Disclosure: VoiceMoat is our product, so treat this section as biased but honest.
ContentIn and VoiceMoat both learn from your own posts. The differences: ContentIn is LinkedIn only and built around a weekly drafted plan. VoiceMoat covers Twitter and LinkedIn with a separate trained voice for each, shows Style live on every draft and a Stance check of what it says, plans toward a goal with Grow, and starts at $35 a month with a $1 trial. If you live on LinkedIn and want drafts to arrive every Sunday, ContentIn is a strong pick. If you post on both platforms and want to check every draft against your own writing, VoiceMoat fits better.
VoiceMoat pricing, October 2026. Annual billing gives two months free. The trial costs $1 for 3 days (Creator) or $5 (Pro and Enterprise), with a card on file, and continues on the plan unless you cancel.
Plan | Price a month | Who it is for |
|---|---|---|
Free | $0 | Looking around; voice training is on paid plans |
Creator | $35 | One to three profiles posting every day |
Pro | $69 | Threads, posting media, Write like a creator, connecting an AI assistant |
Enterprise | $150 | The Deep writing model, team seats and the most profiles |
How it posts: on Twitter, VoiceMoat posts and replies directly. On LinkedIn, posting and scheduling are native, the Chrome extension writes comments straight into LinkedIn’s comment box for you to post yourself, and analytics come through the extension too, because LinkedIn’s API rules are stricter. For the wider field, see the best LinkedIn tools in 2026 and the explainers on Supergrow, Kleo and Taplio.
Is ContentIn worth it?
For a LinkedIn-only founder who wants a week of drafts in their voice every Sunday, ContentIn at $39 a month ($31 yearly) is good value, and the 30-day refund lowers the risk. Weigh the caveats: it is LinkedIn only, the trial needs a card, company pages need Pro, and there is no per-draft voice check. If you post on Twitter too, compare it with VoiceMoat first.

Every social MCP connector reaches both platforms. That is not the hard part
We were going to write that connecting one assistant to both Twitter and LinkedIn was rare. It is not. More than twenty connectors do it and several are free, so channel coverage is table stakes and every roundup ranking them by it is measuring the wrong thing. Here is what actually differs between them, and the one thing we read enumerated tool lists for six of them to confirm nobody does at all.

Why your Claude writing skill doesn't sound like you
There are dozens of free Claude skills for writing, and almost all of them do the same thing: strip out phrases that read as machine-written. That is subtraction, and it leaves you sounding like nobody in particular rather than like yourself. The handful that actually learn a voice from your own writing have a fraction of the users. Here is the difference, why a skill cannot post anything no matter what it says, and where the file actually goes on every surface.
