Weights AI

Weights AI gives you two ways to hear a song differently: change who sings it, or change what genre it is. AI covers swap the singer. Pick from 2,000+ community voices or your own trained voice, upload a song, and Weights AI separates the vocal, re-sings it in the new voice and mixes it back with the original music. The melody and timing stay the same; only the voice changes. A cover takes about a minute. AI Song Remix swaps the arrangement. Upload a track up to six minutes long, pick a style such as piano, phonk, EDM, rock, lo-fi, R&B, K-pop or metal, or describe your own, like "1970s funk, slap bass, falsetto chorus". Choose female, male or instrumental vocals and set the tempo if you like. In one to three minutes you get two new versions with the melody and lyrics kept, performed with new instruments and sung by an original AI voice. Together they cover a lot of ideas: a piano version of a love song for a wedding video, a phonk edit for gaming clips, a cartoon character singing a pop hit, or your own demo heard in three genres before you commit to one. Everything runs in your browser and finished tracks download as MP3s. New accounts get free credits for a first cover. A cover costs 10 credits and a remix 15, plans start at $6.99 a month, and credits from failed jobs are refunded automatically.
