MidiMusic

MidiMusic is an AI songwriting studio that runs entirely in the browser. You describe a track in plain language — mood, genre, instruments, voice type — or paste in lyrics you already have, and the platform returns a finished song with sung vocals or an instrumental backing. Runs typically produce two versions, so you can A/B them before deciding which to keep. Everything you make lands in a library where you can keep shaping it rather than downloading and re-uploading files.

The generator offers two working modes. Simple mode writes the lyrics for you from a description, which is ideal for quick ideas, jingles and first drafts. Custom mode sings lyrics you paste in with [Verse] and [Chorus] tags, and lets you set a title, a style line and a target length from 10 seconds up to six minutes. Four model characters — Standard, Fast, Wild and a separate Long song model — let you trade off natural vocals, speed or experimentation.

Beyond generation, MidiMusic bundles a post-production toolkit: extend a song from any point, restyle it into another genre while the melody survives, strip vocals into two files, split the mix into up to 12 stems, export WAV, or render an MP4 music video. A set of browser-side utilities (BPM and key finder, audio-to-MIDI, slowed and reverb, MIDI to MP3) runs on your own device and costs nothing. AI actions are paid with credits, and failed generations are refunded automatically.
