This is an example of an agent you can build in Sylvie: give it an idea, a launch or a question and it writes a Reddit post shaped for the exact subreddit you are targeting, rules, flair, title conventions and register included. It runs on your brand brain (approved voice, the numbers and product facts it may cite, disclosure rules, and the threads that already landed well), so the post reads like a person with something worth sharing rather than marketing that wandered in. You assemble it inside Sylvie and point it at your own brand: nothing here is pre-built or 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.
Reddit Post is a working example of an agent your team can build on Sylvie. Hand it a topic and it writes the whole thing the way Reddit rewards: a plain title a human would actually type, a body with real substance and specifics, the affiliation disclosed up front, and no marketing cadence anywhere in it.
Reddit is the highest-risk, highest-return social channel a brand has. It sits at the top of Google for buying-intent searches and feeds the AI answer engines, but every subreddit has its own rules, its own tolerance for self-promotion and a community that identifies a marketer in one line. Because this agent writes from the brand brain and from what each community expects, teams can show up where their category is genuinely discussed without burning the account on the first post.
Before it writes, the agent reads that brand's brain: the voice a founder or engineer would actually use in a comment thread, the product facts and numbers it may cite, the comparisons that are approved, how affiliation should be disclosed, the phrases that read as corporate and are banned, and the posts and comments that have already landed well. It also reads the target subreddit's rules and conventions, so a post for a practitioner community is not the same post you would put in a founder community.
Then it drafts inside Sylvie, shaped for Reddit specifically: a title with no hype in it, a first line that gives before it asks, real detail in the body, the right flair, and a disclosure line where the community expects one. It flags anything that would trip a subreddit's self-promotion rule before you publish. Approve, edit or regenerate, and each post traces back to the brain it came from, so nothing goes up that the client has not actually approved.
No hype, no emoji headers, no press release cadence. The agent writes in the register of the community you are posting into, which is the only reason a brand post survives its first hour.
Self-promotion limits, title formats, flair and disclosure requirements differ in every subreddit. The agent shapes the draft to the one you are targeting, so a mod does not remove it ten minutes after it goes up.
Affiliation is stated the way that community expects, following the rules stored in the brain. The brand builds trust instead of getting called out as a stealth marketer in the top comment.
Reddit rewards posts that give something away: a real process, a real number, a real mistake. The agent pulls that material from what the brand has approved, so the post earns its place in the feed.
Reddit threads rank for high-intent searches and get cited constantly by AI assistants. A post the community upvotes keeps working for years after a paid campaign would have ended.
Each brand runs on its own brain and its own subreddit strategy, so an agency can handle Reddit for several clients without one client's voice, numbers or disclosure rules leaking into another's post.
A few of the moments where a Reddit Post agent, built on your brand brain, gets a brand into communities that usually reject them. Each one is a post someone would otherwise be too nervous, or too busy, to write.
A product launch needs to reach a community allergic to launch posts. The agent writes it as a build story with the real details and a clear disclosure, tuned to that subreddit's rules, so the launch gets discussed and upvoted instead of removed inside the hour.
Somebody asks for recommendations in a subreddit where your buyers live, and the window is a few hours before the thread dies. The agent drafts a genuinely useful reply from your approved positioning, so a team member responds the same afternoon with something that helps rather than a link drop.
A client wants an AMA and has no idea what to prepare. The agent drafts the intro post, the credential line and answers to the questions the community will predictably ask, all from the brain, so the founder shows up prepared and the thread fills instead of stalling at three comments.
The brand is sitting on original numbers from its own customer base. The agent turns them into a post with the methodology visible and the promotion stripped out, so the brand earns thousands of views and a credible mention in a place that would never accept an ad.
A thread is spreading outdated or plain wrong information about the product. The agent drafts a factual, non-defensive reply using only approved facts, so the record gets corrected quickly and the response reads as a person being helpful rather than PR damage control.
A brand wants credibility in a subreddit months before it has anything to sell there. The agent keeps a steady drip of useful posts and comments in that community's register, so by launch the account has history and karma instead of showing up cold on day one.
A generic tool produces marketing wearing a hoodie, and Reddit spots it in the title. This is an agent you build on your brand brain: it writes from your real numbers, your approved claims and the voice a person on your team actually uses, and it shapes the post for the specific subreddit rather than for "Reddit" in general.
That is exactly what the rules in the brain are for. You define when the brand can be named, how affiliation is disclosed and which communities are educational only, and the agent drafts inside those limits and flags anything that would break a subreddit's self-promotion rule before you publish.
No, and there is no code involved. You approve what the agent may read from your brand brain, tell it which communities you are targeting and how you want to show up in each, and Sylvie assembles the writer around it. This page is an example of what teams build for themselves, not a template you buy.
The brain is what it draws on: the voice, the product facts and numbers it may cite, the approved comparisons, the disclosure rules, the phrases that read as corporate, and the threads that already landed well. Every post is assembled from that approved material and traces back to its source.
Always, and on Reddit you want to be. The agent drafts and flags the risks, a person reviews and publishes from a real account, and the comments underneath stay human. You decide how much passes through review before anything goes up.
Each brand runs in its own permission-aware brain, so the numbers one client lets the agent cite are invisible to every other account. Sylvie only ever sees what your connected tools already allow, each draft is logged with the source behind every fact, and your brand knowledge stays yours.
