Long AI briefings do not automatically make agency projects better. At the Digiday Media Buying Summit at the end of October, 2026 agency leaders complained about documents full of marketing jargon in which the actual campaign goal gets lost. M&C Saatchi North America chief Nadja Bellan-White estimates that around 85 percent of client briefings arriving today are already written with the help of AI. Her point: with a lot of text, the decision about what the campaign is supposed to achieve is often missing.
For German marketing teams, this is more than a question of writing style. Every unclear briefing triggers queries, correction loops and new coordination – precisely where generative AI should actually be saving time.
The bottleneck sits before content production
How widespread AI support in marketing has become is shown by the Basis report "AI and the Future of Marketing 2026", published in October. For the study, 184 marketing and advertising professionals were surveyed in August. According to it, 51,1 percent of the organisations surveyed use AI agents; of these, 56,4 percent use agents to create campaign briefings. At the same time, only 6,5 percent measure the return on their AI investments against defined benchmarks.
The technology is therefore already producing specifications for creative teams, while the control of its use lags behind. Anyone who only measures the time until the finished PDF overlooks the effort after handover to the agency: clarifying target group and budget, missing sources and repeated drafts.
This also explains why the new complaint about AI briefings meets a much older problem. The BetterBriefs Project had already surveyed more than 1.700 industry people in 70 countries before the GenAI boom. 80 percent of marketing managers considered their own briefings good; only ten percent on the agency side agreed. AI is thus accelerating a process in which clients and executors often already had different ideas of clarity beforehand.
How a prompt becomes a usable brief
A good briefing answers five decisions in plain language: Which business problem are we solving? Whom do we want to reach? What should this audience do afterwards? Which budget and time frame apply? How will we recognise success? For a social campaign, specific channel requirements, available assets, usage rights and approval routes are added.
AI can summarise audience material, formulate competing approaches or flag inconsistencies in a draft. Strategy and the final priority, however, should stay with the responsible marketing team. A useful approval test: after a five-minute discussion, can client and agency both state the same campaign goal in one sentence?
Srocket had already looked at the link between speed and real impact in the Dentsu CMO study2026 on AI and brand consistency. And the two-person agency model from BaD Mktg shows that automation works best when responsibilities and review steps are cleanly organised.
Data checking saves more than polished wording
The risk goes beyond empty phrases. For a study on the reliability of AI insights published in September, the research firm GWI surveyed more than 450 marketing professionals in the UK, the USA and Singapore. 44 percent reported that incorrect AI output caused rework; 37 percent cited financial losses from misleading insights. These figures concern AI insights in general and illustrate why audience and market claims in briefings need a verifiable source.
In high-output teams, a short editorial review path is therefore advisable: enter the data source and reference period, name the most important marketing decision, clarify open points at the kick-off and only then generate campaign variants. Which additional review infrastructure becomes sensible when scaling AI content is shown by Opella's system with specialised control agents.
Fewer pages, faster decisions
Reports from the Digiday Media Buying Summit (5 November 2026) show a shift: the scarcest factor in the campaign process is no longer text production, but the ability to weigh requirements. Those who reduce their briefing to goal, evidence, responsibilities and measurement before using AI give creative teams more direction and have less to explain later.
This aligns with the WARC analysis on AI, strategy time and declining in-person customer research: productivity comes not from generating as many documents as possible, but from making better decisions with the time gained.
