Meta has unveiled Waddle World, a mobile app that combines AI with raising a virtual pet. A key feature is that when users chat with pixel characters reminiscent of 16-bit games, the AI organises the conversation into a diary.

Japan's GIGAZINE reported on Oct. 29 that Meta recently released the AI pet-raising app for iOS and Android. It is currently available for free only in the Philippines, and the minimum age is 18.

Waddle World operates in a similar way to the once-popular virtual pet game Tamagotchi. Users hatch a pixel pet from an egg, then feed it and play with toys to build a relationship.

The core feature is AI-powered conversation. When users talk about their day by microphone or type text, the pet writes a diary from its own perspective based on the content. It also generates a simple drawing depicting the conversation.

It is designed to respond by reflecting the user's daily life and interests as conversations continue. It also offers a feature that sends customised postcards and messages each week based on conversations with the user.

The app also includes mini-games. Users can collect stamps through short games such as stacking groceries, collecting stars and word-matching, and use them to buy food or toys for the pet.

Meta introduced Waddle World as a relaxed virtual space rather than a game that requires daily logins or a productivity tool. It said the app is designed to let users visit freely at their preferred time, without forcing attendance streaks or ranking competition.

The release is seen as an attempt by Meta to expand AI use from work support to everyday communication and entertainment. Meta previously introduced an AI game-making tool called Pocket and an AI video generation service called Vibes.

It is also developing a small device called Muse Charm linked to its AI agent Muse. A direct connection between Waddle World and the device has not been confirmed.

No timeline has been disclosed for launches in other countries such as the United States and Japan.
