Sing Maker is a web app that generates vocal exercises made to measure and turns practicing into a game. Singers, voice students and teachers usually rely on a fixed catalog of warm-ups that doesn't fit their voice, level or taste, and the people who write custom exercises are voice teachers. Sing Maker uses AI as an on-demand composer of vocal exercises: you describe an exercise in text, say or sing the request by voice, or upload a photo of sheet music or a drawing of a melody, and the app writes a validated exercise adapted to your vocal range. You then sing it while guiding a character: notes are perches with stars, the character follows the pitch you sing (detected in the browser; your audio never leaves the device), and you collect the stars when you hit the note in tune. It also includes a level test, a daily routine, drum accompaniment in 4/4 and 6/8 (patterns can also be created with AI), and a shareable result card. Players can create their own characters, collectible items and backgrounds with AI. It works on a phone held sideways, can be installed as a PWA, and has a demo mode that needs no microphone.
