What happens when a chocolate bar meets cutting-edge tech? Twix has the answer with its latest innovation: "Twix Harmoniser", a playful voice-based chatbot designed to turn simple voice messages into harmonized audio duets. Developed in collaboration with WhatsApp, Meta, and creative agencies like Omnicom Reputation Group and adam&eveDDB London, the feature launched in April 2025 in France and Germany, marking a bold new chapter for the brand.
Twix Harmoniser is part of the brand’s new global platform, “Deux, c’est plus qu’un” (Two is better than one), a concept that moves away from the old “left bar or right bar” dilemma to embrace the joy of doubling everything—especially fun.
Available directly via WhatsApp, the Harmoniser uses AI and audio processing to turn a standard voice message (3 to 15 seconds long) into a quirky, tuneful duet. It’s slightly autotuned, delightfully offbeat, and unmistakably Twix. The goal? To tap into the daily habits of younger consumers, particularly Gen Z, who favor voice notes as a form of personal and expressive communication.
More than just a marketing stunt, Twix Harmoniser reflects a deeper brand shift. By stepping into the world of digital creativity and participatory culture, Twix aims to become more than a treat—it becomes a tool for connection, laughter, and self-expression. It’s a playful nod to a generation that loves to create and share.
As Paola Soto, Head of Communication and Sustainability at Santo Domingo Motors, might say in a parallel campaign, it's about using brand platforms not just to advertise, but to engage meaningfully. In the case of Twix, that means letting users literally "sing together"—a joyful reminder that everything really does sound better in twos.
So the next time you're about to send a voice note, why not turn it into a Twix-style duet? It might just make someone’s day a little sweeter—and a little more in harmony.
