KERTASMU is a digital platform designed to help people explore personal growth while connecting through shared knowledge and community discussions. Its services bring together self-discovery tools, practical growth activities, AI-supported guidance, news, and social interaction in one place. Visitors can take short assessments on topics such as personal growth style, mental energy, and brain strengths, then explore campaigns that encourage small, manageable steps toward goals such as building habits, improving wellbeing, or overcoming fear.

KERTASMU also offers Leila, an AI chat service that helps users think through concerns and create personalized micro-campaigns. Members can share perspectives, join discussions, and follow news, trends, and job openings. The platform supports multilingual content and includes community groups and growth missions, with progress-saving features described in its privacy policy. Users can register through Kakao, Google, Naver, or email. KERTASMU presents itself as open to everyone and emphasizes protecting personal information. Its homepage announces a planned grand opening in early October and notes that service updates may affect sign-up and login.
