MusiCraft AI is an all-in-one AI music agent that generates songs, splits stems, masters tracks and turns audio or printed scores into sheet music, MIDI and MusicXML. Its free AI stem splitter offers 75 separation modes — from two-stem vocal and instrumental splits to four- and six-stem mixes and full-band eight-stem separation, plus drum kit, choir, guitar, piano, strings, brass and woodwind isolators — with an in-browser player to solo and mute stems before downloading. The same account covers song generation from prompts, lyrics or hummed melodies, mastering, BPM and key detection, and score transcription. New accounts get free credits with no credit card required, and paid plans add monthly credits for heavier workloads. Uploads accept MP3, WAV, FLAC or M4A up to 100 MB and ten minutes, and most separations finish in under two minutes. It suits producers, singers and editors who need clean vocals, drums or bass from a finished mix, or a quick song starter from a rough idea.
