Overview
Maru is a personalized AI-powered mobile app for schedule management and memo creation, built with the OpenAI API. As creative director and designer, I led the brand identity, shaping the product from concept through final interface.
The goal was to make AI-assisted productivity feel approachable and warm rather than clinical. The brand centers on a black cat character mascot and a soft, geometric visual language built around the keywords: simple, geometric, kitsch.
Brand Identity
I designed the full brand system: wordmark logo, draft of the character mascot, color palette (soft yellow #fff494, blue #5c80c9, white), and typography pairing (Nanum Square Neo and PaperLogy).
UX/UI Design
The app features an AI chatbot home screen with speech recognition, a calendar and schedule management system, a memo page with AI-powered summarization, and a to-do list. I designed each screen to feel simple and intuitive, keeping the cat mascot present as a conversational anchor.
Outcome
I have delivered a complete brand identity system and high-fidelity UI design for a capstone project. The design system unified the product's playful personality with clean, functional interfaces, demonstrating how character-driven branding can make AI tools feel personal and inviting.
