TuneSplit is an AI song generator bundled with a set of free music tools, built around the idea that a finished song is the start of a workflow, not the end of one. Describe a song in plain words or paste your own lyrics, pick a style, mood and vocal, and the generator returns a complete track; paid generations return two versions from two different models, MiniMax Music v2 and ACE-Step, so you can choose the arrangement you prefer. Every browser gets 40 free credits a day, enough for one free generation, with no sign-up, and free songs carry the same commercial licence as paid ones. Around the generator sit practical utilities that work on any audio: a vocal remover, a four-stem splitter and a vocal isolator powered by Demucs, a BPM and key finder, a pitch and speed changer, a lyrics generator and a lyric video maker that renders vertical or widescreen MP4s in the browser. A daily song challenge gives everyone the same theme to write to, with voting and a leaderboard. Paid plans start at $9.90 a month for longer songs up to three minutes and more monthly credits, with one-time credit packs from $4.90. TuneSplit suits songwriters, content creators and musicians who want a quick song plus the tools to remix, practise and publish it.
