AI Ad Creative Production, According to a 14-Year Ad Designer: AI Makes the Sources, Humans Finish the Work

AI Ad Creative Production, According to a 14-Year Ad Designer: AI Makes the Sources, Humans Finish the Work

AI is now the default in ad creative production. Kim Hye-jin, a 14-year designer and deputy team lead at creative.Lab inside Korean ad-tech firm Mobidays, told Mobiinside that “there are almost no cases where we don’t use AI in day-to-day work.” Yet deciding what makes a good result, she says, is still a human job.

How the team changed in a decade

When she joined in 2016, everyone was a graphic designer and there were no sub-teams. Today the group is split into graphics, video and copy. As ad creative expanded from single images to video and copy, the expertise split too.

What AI handles and what people handle

AI has sharply cut the time spent on tasks that used to drag: cutting out subjects, generating missing backgrounds for cropped images, creating objects that once lived only in the imagination, and producing composite shots that look professionally staged.

Banners generated end to end by AI, including text, still look obviously AI-made. So her approach is to use AI for source material and handle text and anything that needs clean finishing by hand. That, she says, is how to produce high-quality ads.

Using AI doesn’t guarantee good work. The ability to judge whether a generated image works, whether it looks off, and what still needs fixing has become more important.

The standard that hasn’t changed

Good creative still connects to the brand and moves people. Not a hook disconnected from the brand, but an ad that is unmistakably the brand while being funny, surprising, cute, relatable or desirable.

She also stresses collaboration. When planners, marketers or clients describe what they want vaguely, designers should point out what’s unclear first. That speeds up direction and reduces revisions.

AI as a teammate

Company AI workshops and study groups helped her team test tools and find the ones that fit real work. In five to ten years, she expects AI skills to be a baseline, with designers managing AI like teammates whose strengths and weaknesses they know.

What marketers should take from this

Split production into AI sources and human finishing

Use AI to generate backgrounds, objects and composites in volume, and keep copy layout and brand elements with people. For an agency that cut workflow time with in-house AI, see Building an In-House AI Platform at an Ad Agency.

Write down your review criteria

Define what to check in AI output, such as brand colors, tone and telltale artifacts like distorted hands or text, so quality decisions don’t vary by reviewer.

Write sharper briefs

When AI makes sources fast, the bottleneck shifts to knowing what you want. Clear references and emotional goals cut revision rounds. For a lean, AI-native marketing team model, see How Liquid Death Is Building an AI-Native Marketing Organization.

Frequently Asked Questions

Which ad design tasks is AI best at today?

Time-consuming source work such as cutting out subjects, generating missing backgrounds, creating objects and producing composite shots.

Why do fully AI-generated banners look off?

When text and layout are also automated, the result still looks noticeably AI-made. Finishing text and clean details by hand raises quality.

What skill matters most for designers in the AI era?

Judging whether AI output works and what still needs fixing, plus communication skills to pin down what collaborators actually want.
