A brand book is not a contract
By Gail Macleod ·
Meta’s ad tools can remember last quarter and draft campaigns. Description is not a rule that decides what may publish.
The signal
On 6 October at Advertising Week New York, Meta expanded Ads Creative Studio and deepened the memory of its AI business assistant — including prior-quarter tests, seasonality, and stated goals. Advantage+ creative can now generate video from static assets (generally available). Agentic actions that plan campaigns, generate images and copy, update targeting, or change budgets from a chat prompt remain in testing; Meta says advertisers keep previews, approvals, and controls over what they delegate.

Separately, Influencers Time’s 13 October read of brand-identity training found only 23% of marketing organisations have a formal policy for how brand assets enter AI training pipelines — while nearly every large brand is already doing it.

The so-what
Thursday’s room is loading guidelines into systems that remember and recommend. So What Law: a PDF that describes voice is not a contract that decides. Fluency is not authority when last quarter’s click winner can quietly rewrite this quarter’s brand promise, or when a model trained on stale claims keeps speaking under your name. Once the platform holds memory and execution authority, the governance problem is no longer “approve this ad.” It is what the system may learn, what it may change, and when a person must stop it.
The distinction
A brand book describes. A contract decides. Description lists colours, tone, and logo rules for humans. A contract binds each claim to proof and expiry, names what performance memory may never overwrite, and assigns who may draft, who must approve, and who may pause. Confusing the two is how a shared-drive PDF stays sacred while the assistant quietly learns, varies, and ships. The question is not whether Meta’s tools are useful. It is whether your brand rules are readable the same way by a person and by a machine before anyone grants more authority.
The move
Before the next agentic creative or budget change: write one page with four lines — (1) what performance may never rewrite (positioning, product names, claim boundaries), (2) which claims need proof and an expiry date, (3) what may auto-adapt vs draft-only vs mandatory human approval, (4) who owns the pause. Cross out any “we’ll keep it on brand” that has no checkable condition. Say it out loud: “A brand book is not a contract.”
