Kakao's AI Transforms Pet Photos Into Emotional Letters in New Experiential Event

Kakao has launched a peculiar kind of experiment: an event that asks people to imagine what their pets are thinking, then lets an artificial intelligence do the imagining for them. Through August 14, users can upload a photograph of their dog or cat to a platform called "Kanana Pet Letter Creation," and within moments receive a letter—complete with a voice reading—purporting to capture the animal's inner emotional life.

The technology behind this is Kanana-o, an AI model developed in-house at Kakao that processes multiple types of information simultaneously: text, voice, and images. A user enters their pet's name, describes their relationship to the animal, and selects one of five voice tones—lively, sly, coy, affectionate, or aggrieved. The AI then examines the pet's facial expression and the objects surrounding it in the photo, synthesizing this visual data into a letter that imagines what the creature might be feeling. The result is packaged as a video combining the original photo with the generated text and audio.

Kakao framed the event as an opportunity for ordinary people to experience advanced AI technology in a way that feels natural and entertaining rather than abstract or intimidating. The company emphasized that the goal was to demonstrate how artificial intelligence could become woven into daily life—not as a distant tool but as something that touches moments of genuine human connection, even if that connection is mediated through a pet.

To prevent misuse, Kakao deployed another proprietary system called Kanana Safeguard, designed to detect and block harmful content generation during the event. The company has positioned safety as integral to making AI accessible rather than as an afterthought.

Participation carries incentives. Everyone who creates a pet letter is automatically entered into a drawing for a KakaoTalk Gift voucher worth approximately $13.50. Those who share their completed letters on Instagram and tag the official Kanana account enter a separate drawing with a prize worth roughly $202. These mechanisms are designed to encourage both participation and social sharing, turning individual interactions into a broader marketing campaign.

Beyond the pet letter event, Kakao is pursuing a wider strategy to normalize AI in everyday contexts. The company has released a video series called "Kanana Original" on YouTube, featuring well-known entertainers—including rapper Nucksal, comedian Kwak Beom, and broadcaster Jonathan—demonstrating Kanana-o's capabilities in conversational settings. In one episode, the entertainers use the AI to generate KakaoTalk message suggestions and analyze photos. In another, a comedian and book editor use it to analyze their bookshelves, write poetry, and propose alternative endings to novels. A third episode positions the AI as a travel companion, providing historical and cultural context about Korean attractions based on photographs.

Kakao's representatives described these efforts as part of a deliberate effort to show users how AI could become practical and useful rather than threatening or alien. The company stated it plans to continue expanding these "touchpoints" between users and AI through varied and creative approaches. The pet letter event and the YouTube series are not isolated experiments but pieces of a larger effort to embed AI into the texture of how people spend their time—whether that's bonding with their animals, consuming entertainment, or planning a trip.
