What it is
RhymeFlux is a rap songwriting app that displays rhyme matches, syllable counts, and flow cues while users write. Live rhyme highlighting matches words by sound for US, UK, Australian, and Canadian English. A syllable counter and Beat Grid flag bars that run long relative to a section. The AI co-writer offers writing and rewrite suggestions in Trap, Drill, Lyrical, and Melodic styles. Users can attach recorded takes to lyric lines; paid plans allow up to 10 takes per line. A beat player loops YouTube beats or plays supplied MP3, WAV, or M4A files. Writing works offline on every plan, with changes syncing after reconnection. The free plan costs nothing and includes one active song with three sections, 15 AI Credits every 30 days, and rhyme highlighting for the first 12 bars of the first section. Monthly access costs $15 a month, annual access costs $99 a year, and lifetime access costs 249.00 USD once. RhymeFlux is available on Android, iOS, and web.
