SeenThis Studio MCP: video ads from chat. Your brand has to come along

A complex video ad in five formats, three languages, two offers. That's normally a working day for a production team. Plus feedback loops.

SeenThis claims: under an hour. From a chat window.

What's new

SeenThis, founded in 2017 and by its own account the video advertising partner for more than 5,000 brands in 50+ countries, launched Studio MCP on November 5. It connects AI tools like Claude, ChatGPT and other MCP-capable assistants to SeenThis Studio. You share a brief, and the AI tool builds editable video ads in multiple formats, using your copy and brand styling. Versions for markets, languages and offers, product feeds, previews for client sign-off. Approved ads go from Studio to DV360 and to Meta and TikTok.

For now it's early access for a select group of agencies and brands. No pricing. The "more than 90% less production time" figure comes from SeenThis's own early tests, with no detail on method or sample.

Chat becomes agency software

What I find interesting: it's the same pattern as Adobe this week. Work moves into the assistant the team already has open. The specialist software delivers, in the background, what chat can't.

CPTO Mark Pasternak puts it neatly: "Your AI tool knows your brand. Our engine knows how an ad has to work." Sounds like a division of labor. In my view it's a shift of responsibility.

Brand governance becomes prompt engineering

The second-order point: if "your AI tool knows your brand", then your brand lives wherever your AI tool learned it. Project instructions, uploaded guidelines, saved prompts. Whoever maintains those is now your brand manager. Whatever their job title says.

Which means the old PDF brand book on the intranet isn't enough anymore. The rules have to exist in a form an assistant applies reliably. Colors, tone, mandatory disclosures, no-gos, labeling. Otherwise you'll produce in one hour what used to take a day. Just wrong, and in five formats.

The catch

Early access, no pricing, a time-saving claim without methodology. For solo founders it's not a purchase decision today. On the plus side: approval happens before anything goes live, and the sign-off preview is built in.

What I'd do now

• Brand rules as project instructions. One page for Claude or ChatGPT: colors, tone, mandatory disclosures, no-gos.
• One approval step before every push. No agent sends ads live without a human signing off on the preview.
• Measure the 90% yourself. If you get early access, produce one real campaign in parallel and time it.

Bottom line: When the ad gets made in chat, your prompt setup is your brand book. Maintain it like one.
