This is an example of an agent you can build with Sylvie: a LinkedIn writer that turns a rough idea, a blog post or a product update into a ready-to-publish post in your brand's voice. It runs on your brand brain (approved positioning, proof points, tone rules and everything you have already posted), so every draft lands on message and sounds like you, not like a generic AI. You assemble it inside Sylvie and point it at your own brand, nothing here is pre-baked or shipped out of the box.
Sylvie does not ship this agent pre-built. It is an example of an agent your team can build with Sylvie, powered by your brand brain, so it runs your workflow the way you actually run it.
The LinkedIn Post agent is an example of what a marketing team can build on top of Sylvie. You give it a starting point (a link, a few bullet points, a campaign angle, even a voice note) and it writes a finished LinkedIn post: a scroll-stopping hook, a skimmable body, a clear CTA and hashtags that match your conventions.
For agencies and in-house teams, LinkedIn is where authority gets built, and it dies from inconsistency. The blocker is rarely ideas, it is the hour each post quietly takes and the drift that creeps in when five people write in five voices. An agent built on your brand brain keeps the voice locked and the cadence steady, so showing up consistently stops depending on who has a free afternoon.
Before it writes a word, the agent reads your brand brain: the approved positioning and tone of voice, the product facts and proof points it is allowed to cite, the words you never use, and the archive of what you have already published. So it writes from what your team actually knows and approves, not from guesswork.
Inside Sylvie you brief it once, and it drafts the post end to end: a few hook options, a body shaped for the LinkedIn feed, the CTA and the first-comment link if that is your convention. Every claim is grounded in a source in the brain, it flags anything it is unsure about, and the draft lands in review ready for a human to approve, tweak or schedule.
A post that used to eat an hour of drafting and second-guessing comes back in minutes. Across a content calendar and a full client roster, that adds up to days returned to the team every month.
Whether it is the company page, a founder's profile or three executives you ghostwrite, each stays deliberately on brand because the voice lives in the brand brain, not in whoever happened to write that day.
Every draft starts from approved positioning and cites its facts, so posts arrive closer to publish-ready and burn fewer review cycles with clients or legal.
Move from a few posts a week to a steady, planned cadence without adding a writer or stretching the team you already have.
The agent holds every angle you have posted and every rule you have set, so nothing repeats itself and no knowledge walks out the door when a social lead moves on.
No invented stats and no off-limits claims. Each line traces back to something approved in your brand brain, so you publish with confidence.
A few of the moments where teams point this agent at their brand brain and let it run. Each one is a workflow you assemble in Sylvie, shaped by your own voice and rules.
Drop in a published article and the agent spins out a series of LinkedIn posts, each pulling a different angle and hook from the piece. What was a Friday afternoon of repurposing becomes a five-minute review, and one long-form asset feeds two weeks of feed.
The agent drafts in the executive's personal voice from their approved talking points and past posts, so their profile stays active. A leader who managed one post a month can credibly publish weekly, with no extra time from them and no new hire on your side.
A product update lands and the agent drafts the announcement post for each brand you manage, on message and in each brand's own voice. What used to be a scramble of individual drafts ships the same morning, with no claim slipping past what marketing approved.
When the person who owns social is on leave, the cadence usually stalls. With the workflow already built, anyone can brief the agent and get on-brand drafts back, so the feed keeps moving and you are not scrambling to backfill or paying for silence.
Point the agent at a client win or a new metric and it writes the proof post, grounded in the real numbers from the brain. A results story that would have sat in a folder goes live the day it is signed off, an hour saved on every post.
Feed it a post that worked and it generates fresh variations on the same theme without reusing the exact copy, checked against everything you have already published. You keep mining a winning angle for weeks instead of burning it in one shot, with no brainstorm required.
A generic tool starts from nothing and guesses at your brand. This agent is built on your brand brain, so it writes from your approved positioning, your proof points, your tone and everything you have already posted. The output sounds like you and stays inside what you actually allow, instead of confident-sounding filler you have to rewrite from scratch.
That is the whole point. The voice, the locked claims and the words you never use live in the brand brain the agent reads before every draft, so it is far more consistent than a rotating cast of writers. And you approve each post before anything goes out.
No, but it is not a pre-built product you switch on either. This page is an example of an agent you assemble in Sylvie, on top of your own brand brain. You start from a proven pattern like this one and shape the voice, the format and the rules to your brand, usually in an afternoon rather than a development project.
The brand brain is the structured memory of your brand: guidelines, tone, product facts, approvals and past work. The agent pulls the relevant pieces before it writes, cites them in the draft, and flags anything it cannot ground in a source. That is why its posts come out specific and accurate rather than generic.
Yes. You can build a version per brand and per voice, each reading its own isolated brain, so an agency can ghostwrite for many clients and executives without wires crossing. Format, length, hashtag rules and CTA style are all yours to set.
Each brand's brain is permission-aware and isolated, so nothing leaks between clients or accounts. The agent only reads what you give that brand, and every draft stays in your review before it is published. Your knowledge stays your asset, structured for your team to build on.
