This is an example of an agent you can build in Sylvie: a display writer that produces the full responsive display ad, the short headlines, the long headline, the descriptions and the business name, each inside its character limit and each in your brand's voice. It runs on your brand brain, so every line pulls from approved product facts, the offer running now and the claims legal has cleared, ready to drop next to your creative. Nothing ships pre-built: Sylvie assembles this agent on your own memory, tuned to how your campaigns run.
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.
Display Ad is a working example of an agent your team can build on Sylvie. Point it at a campaign, an offer or an audience and it writes the whole responsive display asset set: five short headlines, a long headline, five descriptions and the business name, every one inside Google's tight character limits and every one in your brand's voice, so it slots straight into the ad builder next to the creative.
For a paid media team or agency, display copy is deceptively hard: it has to say something in thirty characters, stay on-brand, survive being auto-assembled into dozens of banner sizes, and it multiplies across every audience, offer and retargeting segment. Because this agent writes from your brand brain instead of a blank field, the lines come back tight, on-brand and compliant the first time, so your specialists assemble and launch instead of wordsmithing against a character counter.
Before it writes, the agent reads your brand brain: the approved value props and product facts, the offer live right now, the tone rules, the claims legal has cleared and the ones it has banned, and the display ads that have already performed for this account. It knows a current promotion overrides last quarter's, and it never crowds a headline with a claim your brand has not approved.
Then it drafts inside Sylvie, to the format display demands. It writes each asset to its exact character limit, keeps the short headlines readable at banner size, makes sure any headline can pair with any description when Google auto-assembles the ad, and returns a full asset set to review. Approve, trim or regenerate, and the whole set stays in one place, sourced back to the brain it came from.
Short headlines, long headline, descriptions and business name all land inside their exact character counts, so nothing gets truncated in the banner or rejected at upload.
Saying it in thirty characters usually means losing the brand; here every line is drawn from your approved voice and facts, so it stays punchy and unmistakably yours.
Because Google mixes and matches your headlines and descriptions across banner sizes, the agent writes lines that read well in any combination, so the auto-generated ad never comes out awkward.
Copy comes back structured and on-message for the design team to drop next to the visual, so words and art ship together instead of waiting on a round of rewrites.
Spin up on-brand asset sets for every prospecting and retargeting segment without briefing a copywriter for each one, so more audiences launch without a bigger team.
The headlines and angles that drove clicks and the claims that are off-limits live in the brain, so winners get reused across campaigns and account knowledge stays put when someone leaves.
A few of the moments where a Display Ad agent, built on your brand brain, earns its keep. Each one is copy your team would otherwise squeeze out by hand, asset by asset, against a character counter.
A client wants display retargeting live for cart abandoners this week. The agent writes a full asset set from the approved offer and a reminder-style angle in an afternoon, so the campaign launches on time and every abandoner sees an on-brand banner instead of a generic one.
A promotion has to run across prospecting, retargeting and lookalike audiences, each needing its own angle. The agent writes a tailored asset set per audience from the same approved offer, so the whole campaign goes live in a single review cycle instead of days of rewriting the same lines.
A programmatic campaign needs dozens of copy variants to test across placements. The agent generates on-brand short and long headlines and descriptions in one pass, so the trader has a full test matrix ready without pulling a copywriter off other work.
A display line that carried the account is starting to wear out. The agent produces a batch of fresh on-brand variants that respect the banned claims and the winning angle, so the specialist ships a new creative test in minutes instead of an afternoon at the character counter.
A brand campaign needs display that sells the story, not a discount. The agent writes headlines and descriptions from the brand's positioning and proof rather than an offer, so the awareness ads stay on message and launch without a separate brief to a copywriter.
A junior has to write display for a brand with tight legal and tone limits. Because the agent enforces the approved voice, cleared claims and every character limit, their first asset set lands at senior quality, so the review is a quick sign-off instead of a rebuild.
A generic tool starts from a blank prompt, ignores the character limits and guesses at your brand every time. This is an agent you build on Sylvie, running on your brand brain: it already knows your approved voice, product facts, live offer and the claims you cannot make, and it writes to display's exact limits, so the asset set comes back usable instead of needing a full rewrite and a manual character count.
Yes, because it does not improvise to fill space. Every headline and description is drawn from the approved messaging and tone in your brand brain, trimmed to the limit without drifting off-voice or inventing a claim legal has not cleared. On-brand is the default, even at thirty characters.
You never start at zero or write a line of code. Sylvie builds the agent on top of your brand brain; you connect your tools, approve what it reads, and the asset workflow runs. The Display Ad agent shown here is an illustration of what teams build, not an off-the-shelf product.
The brand brain is the memory it executes on: your product facts, live offer, tone rules, cleared and banned claims and past winning display lines, pulled from the tools you already use and kept current. Every asset is assembled from that approved material and traces back to its source, so it reflects the latest state of the account.
Yes. You decide which claims are off-limits, how copy maps to your audiences and campaigns, how it hands off to the design team, and how much a human reviews before launch. The agent adapts to how you run display, because you build it on your own brain and your own rules.
Each account lives in its own isolated brain, so nothing from one brand is reachable from another, and Sylvie sees only what the tools you connect already expose. Every asset the agent reads or writes is logged and traceable, and nothing trains a foundation model.
