Overview

To promote Joe & Hailey's new "Saju" (fortune-telling) feature without turning the app into a mystical fortune service, I created a solo campaign from the perspective of a judgmental cat pushing its homebody owner toward a date.

I built a fast AI pipeline and voiced the cat's sassy persona myself, then cut it with rapid jump cuts that masked the AI look. Framing the feature as a playful icebreaker rather than a core offering protected the brand, Saju usage rose 40% and the format was greenlit as an ongoing series.

The Constraint

Two problems at once:

Promote a fortune-telling feature without repositioning the brand as a mystical / fortune service.
AI generated video that reads as obviously AI erodes brand trust.

The Approach

A character solves both. Inspired by the viral Korean meme "정서불안 김햄찌," a judgmental cat pushing its lazy homebody owner toward a date gives the feature a low-stakes, playful frame, an icebreaker, not a core offering. Then craft in the edit hides the AI seams.

The Craft

I acted as both creative director and technical executor, building a controlled AI production pipeline rather than leaving anything to chance:

Reverse engineered the prompts: instead of guessing, I sourced reference visuals for the exact mood I wanted and used AI to extract precise descriptive prompts from them, then fed those into Gemini to generate the core stills.
Keyframed the motion: I generated specific first and last frames in Gemini and used AI video tools to bridge them into controlled sequences that followed my storyboard, instead of random video generation.
The "Kim Hamster" edit: rapid-fire jump cuts (channeling that same meme's chaotic energy) held attention and strategically masked the "AI generated" feel, so the clip reads as a raw, native social video rather than a synthetic render.
Directed the humor: I steered the AI toward specific micro-expressions: when the owner reads the "Fiery Fox" (불여우) result, the cat visibly shrinks back, intimidated, then breaks into a dramatic, villainous laugh. The kind of character beat that makes people rewatch.

To bring the "Judgmental Cat" concept to life within a tight timeframe, I developed a highly efficient, AI-collaborative production pipeline, acting as both the creative director and technical executor.

Reverse Engineering Visuals with AI: I began by sourcing specific visual references that matched the desired mood. Instead of guessing prompts, I used AI to analyze these references and extract precise, descriptive text prompts. I then fed these exact prompts into Gemini to generate the core still images.

Keyframing AI Video Sequences: To create fluid motion, I didn't rely on random video generation. I carefully generated specific first and last frame images using Gemini, and then used AI video tools to bridge these frames into seamless, controlled video sequences based on my storyboard.

The "Kim Hamster" Editing Technique: To capture the chaotic, viral energy of the Korean "Kim Hamster" meme, I employed rapid fire jump cuts. This fast-paced editing not only kept the viewer's attention but also strategically masked the typical "AI generated" feel, making the video look like a raw, native social media clip rather than a synthetic render.

Voice Acting & Modulation: To give the cat its signature sassy persona, I recorded the voiceover myself and applied voice modulation to achieve the perfect comedic pitch.

Also I recorded the cat's sassy persona and applied voice modulation for the right comedic pitch.

Results & Impact

Saju feature usage +40% post-campaign.

Format greenlit as an ongoing series.

Framing is a design decision. The same feature, positioned as a core offering, would have put the brand at risk; positioned as a playful icebreaker, it deepened engagement.
