This uses the same engine as naming, in a different order. Before any candidates are suggested, your current name's stroke frames, sound elements and radical elements are diagnosed first. Only then does it suggest candidates that fill what your Four Pillars lack, automatically excluding anything matching your current name. A one-line reason for wanting to rename is used only to inform how the AI explains the result — never to score or rank candidates. A legal rename in Korea requires family court approval; we only calculate and present candidates.
