A large-scale static advertising campaign for Brilliant, an AI-powered educational platform for middle and high school students. The campaign spans 40 creative variations across two formats (9:16 and 1:1), built around eight distinct messaging angles targeting the American parent market. At the heart of the campaign is Koji — Brilliant's AI tutor mascot — brought to life through a custom illustration system covering multiple emotional states. Lifestyle photography was developed in parallel, pairing realistic editorial imagery of diverse student archetypes with generous negative space designed to accommodate Koji and UI overlays in post. The work covers concept development, prompt engineering for AI-generated imagery, and full production documentation — balancing premium editorial quality with the warmth and accessibility the brand needs to connect with families.
