Media Plan Builder is an example of an agent your team can assemble in Sylvie: hand it the brief, and it drafts a full media plan, channel mix, budget split and flighting, built on your brand brain, where each client's budgets, approvals and past performance already live. It reads what worked last quarter, respects the constraints that brand has signed off, and hands your planner a first draft to sharpen instead of a blank page to fill.
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.
Media Plan Builder is a workflow agent you build in Sylvie, not a template you download. It takes a campaign brief and produces a structured first draft: channel mix, budget split, flighting and the rationale behind each call, all drawn from the brand brain your team has been building one client at a time.
For an agency or an in-house team, the plan itself was never the slow part. The slow part is reassembling the context that makes it sharp: what the budget allows, what performed, what the client will and won't approve. When that memory is structured and an agent does the first pass, the plan starts smart and your planners spend their time on judgment instead of lookup.
You point the agent at the brief. It reads that brand's brain, the approved budget and what's already spent, the channel and flighting decisions that worked, the performance history and the rules the client has signed off, then pulls only what's relevant to this campaign. Because the brain is permission-aware and isolated per brand, it never borrows one client's numbers for another.
Then it runs the plan end to end inside Sylvie: it allocates budget across channels, sets the flighting, writes the rationale in your house voice and checks every line against the client's constraints before anything surfaces. Your planner opens a draft that already holds the context, edits it, and ships. You shape how it reasons, so it plans the way your team plans, not the way a vendor assumed you would.
A first draft that used to eat a day or two now lands in minutes. Your planners edit and pressure-test instead of assembling from zero.
Every draft is built from that client's approved budget, rules and channel learnings, so plans stay consistent no matter who is staffed on the account.
The agent checks each plan against approved constraints before it surfaces, so fewer drafts bounce back from the client or from your own leads.
Take on more brands without adding planners just to keep context straight. The agent absorbs the reassembly, so the agency grows in accounts, not hires.
Every plan the agent reads and produces feeds the brand brain. Nothing walks out the door when a planner leaves, and each plan starts from more than the last.
Junior and senior planners start from the same structured context and the same approved rules. First drafts hold the same standard whether it's your biggest account or your newest.
A few moments where a Media Plan Builder, assembled on your own brand brain, changes how the week runs. Each one is a workflow your team could shape inside Sylvie.
A prospect wants a media plan with the pitch, and you have days, not weeks. The agent drafts a costed plan from the category learnings already in the brain, so your strategist walks in with a credible first pass instead of a rushed one. What was a two-planner scramble becomes an afternoon of refinement.
Every account needs a fresh plan for the new quarter, all at once. Instead of each planner rebuilding from spreadsheets, the agent produces twelve first drafts from each brand's own budget and performance history. The team edits in parallel and closes the quarter's planning in days instead of three weeks.
The approved number moves and the whole flighting has to be re-cut. The agent re-runs the plan against the new budget in minutes and flags what no longer fits. Your planner reworks one draft instead of rebuilding the sheet from scratch, and the client has an updated plan before Monday.
A new hire lands on three live accounts they have never touched. Because the agent drafts from each brand's structured brain, they ship a competent plan in week one instead of month two. You add capacity without waiting for someone to absorb years of account context.
An always-on client expects a refreshed plan every month, and it quietly eats a planner's time. The agent regenerates the draft from the latest spend and performance, so the monthly plan takes an hour to finalize, not a day. The retainer stays profitable instead of slowly eroding your margin.
Staffing shifts, and suddenly the same client gets plans that don't look like they came from the same shop. With the agent drafting from one approved set of rules and learnings, every plan starts consistent regardless of who is on it. Fewer surprises for the client, fewer rewrites for your leads.
A generic tool starts from the public internet and guesses. Media Plan Builder is an agent you build on your own brand brain, so it plans from this client's real budget, approved rules and performance history. It isn't producing a plausible plan, it's producing yours.
No, and that's deliberate. This page is an example of what a team builds with Sylvie, not a product you switch on. Sylvie assembles the agent on your brand brain and shapes it to how your team plans, so it reflects your accounts rather than a generic default.
Yes, because the agent only reasons over each brand's structured, approved context: its budget, its channel rules, its constraints. It checks every draft against those rules before surfacing, so on-brand and on-budget are the starting point, not something you enforce afterward.
The brain holds each client's budgets, approvals, flighting decisions and performance, structured and kept current. The agent reads only what's relevant to the brief in front of it, and because the brain is permission-aware and isolated per brand, one client's numbers never leak into another's plan.
That is the point of building rather than buying. You set the channel logic, the budget rules, the format and the house voice it writes in, and you can adjust any of it as your approach evolves. The agent plans the way your team plans, and it changes when your team does.
Your brand brains stay isolated per client and permission-aware, so the agent only ever sees what it is cleared to see. Nothing is pooled across clients and nothing trains a shared model. The plans it produces are built from your data, for you.
