The LinkedIn AI ghostwriter that writes posts like you — and gets sharper every week.

Generic tools start from a blank slate, so everyone gets the same recognisable 'AI voice'. ContentIn trains a personal model on your own LinkedIn posts — your hooks, rhythm and topics — so drafts sound like you, and it gets sharper every week as you edit and publish. It also runs the whole loop (ideas, drafting, scheduling, analytics) in one place instead of leaving you to copy-paste between a chat window, a scheduler and a spreadsheet.

That's the entire point of the product. ContentIn builds your personal writing model from at least 20 of your existing LinkedIn posts, learning your hooks, your sentence rhythm and the topics you keep returning to. Every draft you keep, edit or publish feeds back into that model, so it gets closer every week. Most people are surprised how quickly it stops sounding like AI and starts sounding like them on a good day.

About twenty minutes. You bring the substance — a few topics, opinions or stories — and the ghostwriter drafts posts in your voice that you can quickly edit and drop onto the calendar. Most founders schedule a full week in a single sitting.

No. ContentIn publishes through LinkedIn's official API as a verified LinkedIn app and connects via official OAuth, so it never asks for your LinkedIn password. Pasting your public profile URL just lets us learn your writing style from your existing posts. You stay in control of what gets published.

No. LinkedIn's algorithm doesn't distinguish between human- and AI-assisted content — it rewards well-crafted posts with strong hooks that people engage with. Their Professional Community Policies ask that content be authentic and genuinely yours, which is exactly the point of a ghostwriter trained on your own voice: you bring the real substance, it handles the drafting.

Yes. Beyond writing, ContentIn generates ideas from your own topics, a saved note, or any URL you paste, and keeps them in an idea manager. It also nudges you toward the themes and formats your audience actually responds to, based on your analytics.

Yes. ContentIn's content calendar allows unlimited post scheduling on every paid plan, and publishes each post at the time you choose through LinkedIn's official API. You can line up a whole week (or more) in one sitting, mix professional and personal posts, and queue a first comment to drop a link or lead magnet right after a post goes live — and it works as a free LinkedIn scheduler for your first 7 days.

ContentIn's Growth plan is $39/month, or $31/month billed annually, and includes your week planned every Sunday plus unlimited AI ghostwriter drafts trained on your own LinkedIn posts — less than most freelancers charge for a single post. Pro is $59/month, or $48/month billed annually, and adds a third planned post a week, unlimited ideas and carousels, company pages and leads analytics. ContentIn has no free plan: every plan starts with a 7-day free trial that asks for a card, and your first payment carries a 30-day refund.

Yes. ContentIn's free AI LinkedIn post generator writes a first draft in about 10 seconds, with no login and no credit card, and generates three personalised posts from your own LinkedIn profile so you can judge the voice-matching before you sign up for anything. When you want the full loop — ideas, the ghostwriter trained on your posts, scheduling and analytics — every plan starts with a 7-day free trial.

Both. You can plan and schedule content for your personal profile and, on the Pro plan, manage company pages as well — handy for founders who post as themselves and for their brand.

Founders first, then solopreneurs, coaches and consultants — people who know LinkedIn matters for their pipeline but don't have the time or the rhythm to post consistently. If you've got things worth saying but keep losing to the blank page and the busy week, this is built for you.

You're always in control. Every draft is a starting point — edit as much or as little as you like, add a real example or number, then schedule it. As the AI learns your voice, you'll find yourself editing less each week.

No. You don't need to be a professional writer to build a personal brand on LinkedIn — you just need the substance. The ghostwriter turns your raw thoughts into structured, engaging posts, so the writing stops being the thing that holds you back.
