About

Music lover and builder based in Japan. Spent years in the music industry (worked on music.jp, one of Japan's early digital music platforms) before going independent. Currently building Opini, an AI-powered music diagnostic tool that helps artists understand their tracks across 8 dimensions — not just scoring, but coaching them toward their next hit. Also running AIRA Project, a multilingual virtual artist project spanning Japanese, English, and Spanish. Always happy to swap feedback with fellow makers 🙌

opini — Will your song reach the world? - AI music coach that scores your track across 8 dimensions

Opini is an AI-powered music diagnostic tool for artists. Instead of a single vague "score," it analyzes your track across 8 dimensions — melody, arrangement, lyrics, and more — and tells you exactly where it's strong and where it needs work. Most feedback tools stop at scoring. Opini goes further: it acts as a coach, giving concrete suggestions on how to improve your next version, not just a number to feel good or bad about.
