Aitane and Dstyle Holdings to Jointly Develop the Beauty and Health AI App cocopi
Aitane Inc. (head office: Chiyoda-ku, Tokyo; Representative Director: Junichiro Aita; "Aitane") and Dstyle Holdings Co., Ltd. (head office: Shibuya-ku, Tokyo; Representative Director, Chairman and President: Mitsutaka Tokuda; "Dstyle Holdings") are jointly developing cocopi, an AI app for beauty and health. A full release is planned for December 2026.
cocopi brings records of meals, weight, steps, sleep, skin, and physical condition together with consultations to AI in a single smartphone app. Drawing on data from about one million people held by Diana, the proportion-making brand, it aims to deliver a healthcare plan suited to each person and an experience in which beauty and health habits can be continued without strain.
Background: making beauty and health management easier to continue in daily life
People may want to understand their day-to-day condition for the sake of beauty and health, but when information on meals, sleep, skin, and skincare is split across several apps and notes, entering and looking back on it can become a burden.
cocopi aims to bring daily records and a place to consult into one, and to reduce the burden of entry and review. Development is proceeding toward an app that not only keeps records, but helps people understand their own condition and connect it to everyday self-care.
Main features of cocopi
1. Manage beauty and health records in one app
Features are in development to manage records such as meals, weight, steps, sleep, skin, and physical condition together. Skincare management, and menstrual-cycle management for eligible users, are also planned. The aim is to make it easier to look back on several kinds of information in one app and to grasp one's day-to-day condition.
2. Consult casually through conversation with AI
A feature is in development that lets people consult AI about beauty and health through chat. Voice input is also planned, to reduce the work of typing and to support a way of recording and consulting casually in daily life.
3. Offer a plan suited to each person, based on data from about one million people
The aim is to deliver a healthcare plan suited to each person, based on data from about one million people held by Diana, the proportion-making brand. Using a person's daily records and conversations as cues, it also aims to offer encouragement and self-care support matched to how that person is doing.
The features described include items still in development. Details may change at the time of the full release. Some features are planned to be offered according to the user and the applicable conditions.
This service supports day-to-day beauty and health management. It is not intended as a medical practice.
About the joint development
As the holding company of Dstyle group, which operates businesses centered on beauty and health, Dstyle Holdings is responsible for the group's asset management, strategy, and shared services.
In addition to developing and operating Aitane, the AI agent that takes over administrative work in sales, Aitane Inc. helps customers introduce AI fitted to their operations and supports people in learning generative AI.
The two companies are advancing the joint development of cocopi by drawing on knowledge of beauty and health and of AI. Through daily records and conversation, they aim for a service in which users can understand their own condition and continue beauty and health habits that fit their lives.
Comments from both companies
Yuto Mita, Executive Officer and Group CTO, Dstyle Holdings Co., Ltd.
A new application, cocopi, has been born.
By simply talking to an AI character, you can easily register daily data such as meals, sleep, and exercise. Based on the data you register, cocopi supports each person's beauty and health as an AI partner dedicated to you.
It provides support for beauty and health grounded in reliable information, using public information from the WHO and Japan's Ministry of Health, Labour and Welfare. It also brings together data from about one million people held by Diana, which works on proportion making, and the know-how Dstyle group has built through its activities so far, to realize an application unlike any before.
Because you can register data simply by talking with AI, it also addresses a common frustration with recording apps: that registration is a chore and hard to keep up. The more data you register, the better cocopi understands you and the more the support it offers fits you. Why not make the cute AI partner cocopi your companion, and aim for beauty and health together?
Junichiro Aita, Representative Director, Aitane Inc.
We want to make AI something people can use close at hand in work and in life, and to increase the time they can spend on what matters to them. Beauty and health are themes deeply tied to everyday living. At the same time, it takes effort to keep recording meals, sleep, and the condition of one's skin, and to look back across several kinds of information and think about care that fits oneself.
With cocopi, we aim for an experience that connects recording and consultation through conversation with AI, and that people can keep using without strain in daily life. What we care about is connecting recorded information to an awareness of one's own condition and to the next action. We want to deliver a service that helps people think about self-care that fits them, as they talk about something that is on their mind or look back on the day.
As we develop cocopi together with Dstyle Holdings, we aim to make managing beauty and health easier to continue as part of life, rather than a special task. We are putting clarity and ease of use first, so that people who are not familiar with AI can use it casually. Toward the full release in December 2026, we will continue development so that cocopi can be a beauty and health partner that is useful in everyday life.
Pre-registration is open ahead of the full release in December 2026
A full release of cocopi is planned for December 2026. The smartphones planned for support are iOS and Android.
Ahead of the full release, a free closed beta test limited to the first 1,000 people is planned, so that users' feedback can be reflected in development. Pre-registration has been open since July 1, 2026. The start date, period, and details of the beta test will be announced separately to participants.
