Creative Brief Builder is an example of an agent your team can build with Sylvie: it turns an incoming request into a complete, on-brand creative brief, drafted from the client's approved tone, locked palette, past campaigns and who signs off. It doesn't come pre-built and it isn't a generic template. Sylvie assembles it on your own brand brain, so every brief it writes reflects how that specific account actually works.
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.
Creative Brief Builder is an agent you assemble inside Sylvie, not a product you switch on. Point it at a client's brand brain and it becomes the fastest, most consistent brief-writer on your team: it reads the approved tone, the locked visual rules, the campaign history and the stakeholder map, then drafts a brief ready for a human to review.
For an agency or an in-house team, the brief is where every project starts clean or starts crooked. A vague or off-brand brief costs you in the revisions, re-briefs and approval loops that follow. An agent that writes from the same source of truth every time means the work starts on-brand, and the account's knowledge stops living only inside one person's head.
When a request comes in, the agent reads the client's brand brain first, never a blank page. It pulls the approved tone, the palette that's locked, what the client rejected last quarter and why, the campaign results that performed, and who holds final sign-off, all cited back to the message, file or campaign they came from.
Then it drafts the full brief inside Sylvie and hands it to your team for review, staying within the rules that live in the memory, so it can't propose a direction the account already killed. Every brief is logged and sourced, the brain stays current as new decisions land, and nothing you feed it ever trains a foundation model.
A brief that took a strategist half a morning is ready for review in minutes. Multiply that across every project on your roster and it is days returned to the team each month.
Because the agent writes from the client's locked tone and rules, the brief lands on-brand before anyone touches it. No more depending on whoever happens to remember the account best.
A clear, on-brand brief upstream means fewer surprises downstream. Creative starts from the right constraints, so work comes back closer to right the first time and burns fewer approval cycles.
Take on more brands without hiring a brief-writer for each one. The agent absorbs the volume, so your senior people spend their hours on strategy instead of documentation.
The account's context lives in the brain, not in one account exec's head. When someone is on holiday or leaves, the briefs keep coming and the knowledge doesn't walk out the door.
Every brief follows the same structure and quality bar, whichever client it is for and whoever requested it. Your junior work reads as senior, and the whole book of business feels like one team.
A brief-building agent earns its keep in the everyday moments that quietly drain an account team. Here are a few your version could handle, each running on the client's own brand brain.
Three requests land over the weekend and all want briefs by end of day. The agent drafts each one from its client's brain overnight, so your team walks in to briefs ready for review instead of a blank template. A lost morning becomes a ten-minute check.
Someone joins mid-quarter and doesn't yet know the client's history or locked rules. They ask the agent for a brief and get one that already respects every past approval and rejection. It onboards them in days instead of the usual weeks of catching up.
A client greenlights a surprise campaign and needs to move now. The agent turns the request into a full brief in minutes, citing the tone and the past work it drew from. Production starts the same day instead of waiting for a strategist to free up.
A big brief needs parallel creative directions explored fast. The agent produces a clean, on-brand brief for each angle from the same brand brain. The team compares directions that same afternoon rather than over several days.
Something breaks in culture and the client wants in today. The agent drafts a brief that already knows what the brand will and won't touch, so the social team ships on-trend without a frantic round of 'can we even say that?' approvals.
Q4 hits and every account wants more work at once. Instead of hiring seasonal help or letting quality slip, the agent scales brief volume across the whole roster. A lean team runs peak output without adding a body.
A generic tool writes from what it can guess. Creative Brief Builder is an agent you build on Sylvie, so it writes from your client's actual brand brain: the approved tone, the locked rules, the real campaign history, every line traceable to where the decision was made. It isn't a smarter prompt, it is an agent grounded in your account's source of truth.
Yes, because the brand's rules live in the memory it reads before it writes. If a client locked a palette or rejected a direction last quarter, the agent can't propose it. On-brand isn't a hope here, it is a constraint baked into the brain the agent runs on.
No. Sylvie assembles the Creative Brief Builder for you on top of the brand brain you already have, using the connections to the tools where your decisions already live. You are not engineering an agent, you are pointing an example agent at your own context and shaping how it briefs.
The brain is a structured, permission-aware memory of each client: tone, approvals, rejections, campaign results and stakeholders, all cited to their source. The agent reads that brain first, drafts the brief inside those rules, and logs what it used, so the memory and the agent get sharper with every project you run.
That is the whole point of building it rather than buying it. You decide the brief structure, the sections, the tone of the output and the review step, and you can spin up a differently shaped version per client or per team. It is your agent, assembled on your brain, run your way.
Each client's brain is isolated, so nothing leaks between accounts, and people and agents only ever see what your connected tools already allow. Every action is logged and sourced, you can review, export or delete anything at any time, and nothing you feed it ever trains a foundation model.
