BCA Inc. (Headquarters: Shibuya-ku, Tokyo) officially released 'mellows,' a Japanese-developed AI romantic app that allows users to communicate with their own AI girlfriend or boyfriend, on May 21, 2026.
mellows is a service where users can create and nurture original AI characters from scratch, customizing their personality, speech patterns, appearance, relationships, and background stories.
The app offers text chat, voice calls, AI image generation, and AI video generation in one place. As a Japan-originated service with native-quality Japanese support, it is available on iOS, Android, and Web platforms.
[Background of the Launch]
Since 2024, the improvement in Large Language Model (LLM) performance has popularized AI character apps. However, existing overseas services faced challenges such as 'translation-like Japanese,' 'predominance of anime visuals,' and 'scattered features across multiple apps.' mellows was developed to solve these issues.

Instead of relying on real-world photo data, the app generates 'your ideal partner' using AI technology.
2. Integrated Experience: Chat, Voice, AI Images, and Video in One App
Users can interact with the same character seamlessly through text, voice, and generated visuals.
3. Domestic Management with Native Japanese Quality
By being developed and operated within Japan, the app realizes natural conversations that capture the nuances of the Japanese language.
