Search Ad is an example of an agent you can build in Sylvie: it drafts complete responsive search ads, headlines, descriptions and extensions, matched to each ad group's intent and written the way your brand actually talks. It runs on your brand brain, so every line pulls from approved product facts, live offers and the claims legal already cleared, all inside Google's character limits. Nothing ships pre-built: Sylvie assembles this agent on your own memory, tuned to how your accounts 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.
Search Ad is a working example of an agent your team can build on Sylvie. Point it at a set of keywords or an ad group and it writes the full responsive search ad: up to fifteen headlines and four descriptions, plus sitelinks, callouts and structured snippets, every one inside Google's character limits and every one in your brand's voice.
For a paid search team or agency, ad copy is the bottleneck that never ends. New offers, new landing pages and new accounts each need dozens of on-brand, policy-clean variants, and it usually lands on one specialist writing them by hand. Because this agent reads your brand brain instead of a blank prompt, the copy comes back on-brand and compliant the first time, so your specialists review and launch instead of drafting from scratch.
Before it writes a word, the agent reads your brand brain: the approved value props and product facts, the offers running right now, the tone rules, the phrases legal has cleared and the ones it has banned, and the search ads that have already won for this account. It knows a current promotion overrides last quarter's, and it never invents a claim your brand has not approved.
Then it drafts, inside Sylvie. It groups copy by ad group and search intent, counts every character against Google's limits, pins the headlines your brand requires (brand name, a legal disclaimer) and returns ready-to-launch variants for review. Approve, tweak or regenerate, and the whole workflow stays in one place, sourced back to the brain it came from.
A full set of responsive search ads that used to take a specialist an afternoon comes back in minutes, per ad group, per account.
Every headline and description is drawn from your approved voice and product facts, so the copy sounds like your brand instead of a generic model guessing at it.
The agent stays inside Google's character limits and only uses claims your brand and legal have cleared, so far fewer ads bounce back from policy or disapproval.
Take on more accounts and more campaigns without hiring another copywriter for every new logo. The agent absorbs the volume; your specialists keep the judgment.
Because it starts from approved facts rather than a blank prompt, copy comes back right the first time, cutting the write, reject and resubmit loop.
Every winning angle and every banned phrase lives in the brain, so your top performers get reused and the account knowledge stays put when a specialist leaves.
A few of the moments where a Search Ad agent, built on your brand brain, earns its keep. Each one is copy your team would otherwise write by hand, ad group by ad group.
A client launches a new product and needs live search campaigns by Monday. The agent drafts every ad group's copy from the approved launch messaging in an afternoon instead of a week, so media buying starts on time without pulling a copywriter off other accounts.
A seasonal promotion goes live and every ad referencing the old price is suddenly wrong. The agent rewrites the affected headlines and descriptions across all ad groups in one pass, so the account is current and compliant the same day, not after three days of manual edits.
You win a new client and inherit hundreds of empty ad groups. The agent fills them with on-brand, policy-clean responsive search ads from day one, cutting weeks off onboarding and letting the account go live without a new hire.
A top ad group needs fresh variants before performance decays. The agent generates a batch of on-brand alternatives that respect your pinned headlines and banned claims, so the specialist ships a new test in minutes instead of an afternoon of drafting.
The same campaign has to run in several markets in the right voice. The agent adapts headlines and descriptions per market from the brand brain, holding claims and tone consistent, so a rollout that meant briefing freelancers ships in a single review cycle.
A junior on the team has to build copy for a brand with strict rules. Because the agent enforces the approved voice, claims and character limits, their first draft lands at senior quality, so the review is a quick sign-off rather than a full rewrite.
A generic tool starts from a blank prompt 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 offers and the claims you cannot make, so the search ads come back usable instead of needing a full rewrite.
Yes, because it does not improvise. Every headline and description is drawn from the approved messaging and tone in your brand brain, and it will not use a claim your brand or legal has not cleared. On-brand is the default, not something you have to prompt for each run.
You do not start from zero and you do not write code. Sylvie assembles the agent on top of your brand brain; you connect your tools and approve what it reads, and the workflow is ready to run. The Search Ad agent on this page is an example of what teams build, not a product you buy off the shelf.
The brand brain is the memory the agent executes on. It reads your product facts, offers, tone rules, cleared and banned claims and past winning ads from the tools you already use, kept current as things change, so every ad reflects the latest approved state of the account and traces back to its source.
Yes. You decide which headlines get pinned, which claims are off-limits, how copy maps to your ad groups and how much a human reviews before launch. The agent adapts to your account structure and approval process, because you build it on your own brain and your own rules.
Each brand runs in its own isolated brain, so nothing from one account is reachable from another, and Sylvie only ever sees what the tools you connect already allow. Everything the agent reads or writes is logged and sourced, and nothing trains a foundation model.
