The Power of AI Personalization in Zalo Mini Apps This Halloween Season
Why are AI Marketing Zalo Mini App campaigns so powerful for a festive season like Halloween? It’s simple: AI enables an unprecedented level of customization and interaction. Users no longer just consume content; they become a part of it. Imagine:
Dynamic Character Creation: AI analyzes user photos to transform them into spooky avatars, mythical creatures, or even brand mascots in real-time, perfectly designed for the Halloween theme.
Personalized Storylines: AI algorithms can generate unique stories or challenges based on user preferences, previous interactions, or even their location, making each user's experience one-of-a-kind.
Interactive Gamification: From AI-driven quizzes that adapt to answers to virtual trick-or-treat experiences, AI enhances gamification elements, making them more engaging and responsive.
Seamless Sharing: As users create their personalized content, the Zalo Mini App facilitates instant sharing across social media platforms, turning each user into a brand ambassador.
This level of interactive marketing isn't just about fleeting fun; it's about collecting valuable data, understanding customer behavior, and building a community around personalized, shareable experiences. For Halloween 2026, brands embracing the combination of AI and Zalo Mini Apps are sure to create the most impactful engagement.
Marvy Co. Case Studies: Putting Users First with AI & Gamification
Marvy Co. believes in pushing the boundaries of what's possible. Our recent campaigns demonstrate how AI-integrated Zalo Mini Apps can transform seasonal events and product launches into memorable, user-centric experiences.
Case Study 1: MILO Fresh Milk A2 – Personalized AI FaceSwap for Brand Connection
To promote MILO Fresh Milk A2, Marvy Co. developed an AI-generation minigame incorporating Faceswap elements on the Zalo Mini App, placing personalization at its core.
Instead of static advertisements, parents could:
Upload Child's Photo: Users upload a picture of their child.
Customize with AI: Users selected keywords (gender, interests, sports, study activities, outstanding skills) describing their child. The system then used AI FaceSwap and AI Generation to create personalized images, seamlessly integrating the child's face and chosen attributes into brand templates.
Share & Get Rewards: Users shared these unique creations on Facebook to receive rewards.
This campaign wasn't just about product visibility; it was about creating a strong emotional connection. By turning each child into a 'star' in the MILO universe, the campaign naturally encouraged User-Generated Content (UGC), amplified social sharing, and provided invaluable data for CRM and remarketing. It stands as a testament to how AI personalization transforms brand promotion into a heartwarming, shareable experience, making users a central part of the story.

Case Study 2: OATSIDE – AI Generation Transforms Users into “On-Air Stars”
With the “Go On Air with OATSIDE” campaign, Marvy Co. applied AI Generation technology to transform users into the central characters of an entertaining and shareable brand experience.
Instead of simply interacting with a conventional minigame, users could integrate their own images into OATSIDE's creative world. This approach is also suitable for developing into AI Halloween Campaigns, where each player can become a unique Halloween version of themselves.
Upload Personal Photo: Users upload a portrait photo to serve as input data for the AI.
AI Face Transformation: The system can use AI FaceSwap / AI Generation to retain the player's facial features while transforming their appearance according to the concept developed by the brand.
Brand Integration: Brand identity elements can be directly integrated into costumes, backgrounds, props, or visual frames, ensuring that AI-generated content is both personalized and maintains brand consistency.
Share & Reward: Players can receive their personalized image/video and share it on social media to participate in a reward mechanism, thereby transforming each AI creation into a UGC asset for the campaign.
The strength of this model lies in its ability to turn an ordinary user into a character within the brand's world. For Halloween, AI Generation can expand the experience from a fixed template into a multitude of different visual versions, giving each player their own unique “Halloween identity.”
This helps brands create a campaign with high personalization, entertainment, and social sharing, while also generating organic UGC that users actively want to share.

Case Study 3: Manulife – Gen AI Personalizes Images into “Your Own Version”
In the “Choose Green for Health” campaign, in collaboration with Manulife – the first foreign-invested life insurance brand in Vietnam, Marvy Co. developed a Gen AI Image Generation Engine that allowed users to upload a portrait photo and select “green signals” such as lifestyle, family, healthy living, or youthful spirit. The AI then analyzed the image and user selections to create a personalized “green version” visual.
Marvy not only developed the AI engine but also conducted multiple rounds of testing with various types of photos, lighting, and camera angles to optimize facial accuracy, lighting, tone, and visual consistency.
This model can be directly transformed into an AI Halloween Generation Campaign:
Upload Your Face: Players upload their portrait photo to a microsite or Mini App.
AI Outfit & Makeup Transformation: AI retains the player's face and identifying features, then changes outfits, makeup, hairstyle, age, and other visual elements according to the keywords chosen by Manulife's customers.
Multiple Creative Directions: Brands can build multiple concepts within the same campaign, allowing each player to create a different version instead of just using a fixed template.
Branded & Shareable Output: The final image integrates the brand's logo, campaign message, product, or key visual before users share it on social media.
The Manulife case demonstrates the power of this model, as the campaign generated 37,482 personalized images from 21,510 participants and 17,745 Facebook shares.

For Halloween, the same technology framework can be transformed into an “AI Halloween Transformation” experience — where users don't just see a Halloween advertisement but truly become part of the brand's Halloween world. From FaceSwap, outfit changes, Halloween makeup, to AI-generated backgrounds, each output becomes a unique visual, increasing the potential for UGC, social sharing, and organic reach for the campaign.
→ This is where Marvy can position AI Generation: not merely as “AI image creation,” but as an AI-powered personalization engine that can be customized according to each brand's concept, visual identity, and marketing objectives.
