01 · Overview
Move an AI persona into a real client campaign.
This project applied Kaya in a branded advertising use case for Presretač. The objective was to create a short, premium vertical ad that paired a recognizable AI character with direct-response messaging, motion typography and a clear call to action.
The work connects persona development with commercial production constraints: brand tone, timing, legible messaging and final-format delivery.
02 · My role
From character application through final delivery.
- Adapted Kaya to the campaign while preserving her recognizable identity.
- Developed AI-generated character footage for a vertical advertising format.
- Shaped the visual tone around the Presretač brand.
- Integrated campaign messaging, typography and motion.
- Iterated pacing and shot timing for social-media use.
- Prepared the final Instagram delivery with audio.
03 · Campaign structure
Four beats, from character hook to brand action.
02 — Direct-response question
The character shot leads into the “Sudar?” hook, pairing Kaya with a bold on-screen message.
03 — Brand message
A high-contrast information card carries “Ne izlazite pred osiguranje sami” and the compensation message.
04 — Final brand CTA
The close presents the Presretač identity, service positioning and contact information.
04 · Character consistency in commercial use
Test Kaya outside the character-sheet setup.
The campaign tests whether Kaya's identity remains recognizable under a different visual treatment. The production checks focused on stable facial features and hair, a premium beauty / lifestyle presentation, and continuity with the established character design.
The goal was practical usability: the persona needed to work inside a branded client deliverable, not only in controlled development images.

Presretač demonstrates the transition from AI character development into practical commercial production.
