Two Years of Growth — From 'Chatting with AI' to 'Supporting AI Characters'

'Oz Chat' is an AI character chat application that unifies conversations with unique original AI characters, illustration generation, video creation, and a secondary creation community. In the two years since its official service launch in July 2024, it has achieved the following milestones:

Total registered users: 220,000

Cumulative conversations with characters: Over 50 million

AI-generated illustrations within the app: Approximately 100,000

User-created original scenarios: Approximately 8,000

A key feature is its community structure, where users, inspired by conversations with characters, become creators themselves—producing illustrations, videos, and scenarios.

On X (formerly Twitter), fan-created hashtags like '#OzChaArt' are regularly posted, and fans independently host 'birthday celebrations' for characters, fostering a culture of 'supporting' AI characters.

Details of the 2nd Anniversary Festival (July 16 – Early August)

1. 21 Characters × 21 Days: New Scenario Cards Released Daily at 5 PM

One of the 21 original characters will take the spotlight each day. A total of 75 new scenario cards—featuring idol outfits, magical girl themes, pajamas, and character collaborations—will be released consecutively over 21 days. The first day (7/16) features the popular character 'Nekone Kohaku'.

2. Free AI Illustration Generation (5 Uses) for All Users

During the event period, all users can experience free AI-generated illustrations of their favorite characters.

3. New Feature: AI Characters Respond to Fan Posts 'as Themselves'

When users tag a character in the app's secondary creation feed, that AI character will view the post and respond with a comment. 'When you draw, your favorite character responds'—a new co-creation experience between fans and AI characters.

4. Launch of the 'Your 2 Years with Oz Chat' Recap Page

A special page summarizing each user's two-year journey—days since first meeting, total conversations, most-talked-to character, and percentile ranking among all users—will be launched. Results can be shared on X.

5. X Sharing Campaign & Retro Merchandise Giveaway

The '2nd Anniversary Share Festival' rewards daily AI-generated bonuses for posting on X. A giveaway campaign offers a chance to win past merchandise (including discontinued items) by following and retweeting.

The campaign will begin on the official X (@0z_chat) at 8:00 PM on 7/16.

Full-Scale Launch of AI Character 'IP Expansion'

On the occasion of its 2nd anniversary, 'Oz Chat' is launching full-scale expansion beyond the app experience, positioning itself as an AI-native character IP.

◎ Release of 5 Commemorative Songs

All 5 songs from the 2nd anniversary commemorative album, performed by the Oz Chat characters, are now available on music platforms including Spotify, Apple Music, and YouTube Music starting July 16.

CEO Statement

Over the past two years, our users have shared over 52 million conversations with our Oz Chat characters, drawn illustrations, created stories, and celebrated birthdays. We believe the unique relationship made possible by AI characters—always available and always responsive—represents a new form of character IP. In its third year, Oz Chat will bring these characters from conversations into music, merchandise, and co-creation spaces with fans.
