    One tune at a time. Your file stays in this browser.

    Small format. Endless possibilities. RTTTL is a wonderfully tiny way to write a melody. These guides shape the notes and rhythm; choose a synth sound to give them a different feel.

    01 / COMPOSE

    Your browser is the studio.

    The melody model runs here with WebGPU, with a CPU fallback when needed. No sign-in, no generation server.

    02 / MAKE IT YOURS

    A little direction goes a long way.

    Try a new tempo, a minor key, a brighter sound. Melody guides are handcrafted hints, ready for your experiment.

    03 / KEEP IT

    Made to leave your pocket.

    Save the tiny RTTTL text or take the sound with you as WAV or MP3. Start something, share something, have fun.
