Help & Guide

How to describe your song

• Be specific: genre, mood, instruments, tempo, artist references
• Good: "Melancholic lo-fi hip hop, muted trumpet, vinyl crackle, 85 BPM, like Nujabes"
• Bad: "Make a sad song"
• All input modes combine: Describe + Lyrics + Reference + URL work together

• Write lyrics — your exact words preserved; only style generated by Gemini
• Reference melody — upload audio → Gemini extracts key/tempo/mood/instruments
• From URL — YouTube/SoundCloud/Shazam → artist+title → Gemini infers style (no audio download — CF Pages limitation)
