MORE + KaiJoo Sketch Service

A fintech personal-finance app that combines social login, bank-account linking, AI-driven budget management, and goal-achievement visualization videos in one flow. Monthly income is automatically allocated across weeks and recalculated against the remaining span when a goal is extended, and a LangGraph-based AI chatbot handles merchant classification and budget advice. Goal visualization videos are produced by a separate pipeline service I designed and still operate (sketch.pyan.kr), which returns MP4, WebM, and GIF assets over a CDN.
