What writers are saying
Actually useful
Been using Apple notes for years but this is way better. It counts syllables and highlights rhymes which actually helps you stay in the pocket before you even record. Good looks
helps me kill my writer's block
Dope app. Word suggestions give you actual slang and slant rhymes instead of just cheesy words like other dictionary apps. helps a lot when I get stuck on a bar. And I like a clean dark design too

The Free Tier: Test the studio on one song.
Start with 1 active song (up to 3 sections: verse, hook, bridge), 15 AI Credits every 30 days (each Credit is one AI generation, enough to test-drive the AI on a verse), and cloud sync across all devices.
The "Spotlight" Rule: Rhyme highlighting and Pro tools shine on the first 12 bars of your first section, then fade to plain text, so you can see what Pro unlocks before you upgrade. Want a taste first? Paste a verse into the free rhyme scheme analyzer.
All prices are inclusive of VAT where applicable. Transactions processed by our reseller, Paddle.
The Pro Studio
Breakdown.
Three chapters. Every tool that makes RhymeFlux the studio rappers actually finish songs in.
Writing Studio
Rhyme Finder
Search any word, get up to hundreds of rhymes grouped by syllable count. Tap one and it drops straight into the bar you were writing. No copy-paste, no leaving the canvas.
Sound-Based Matching
Matches words by sound, not spelling. "Time" rhymes with "Mine," "God" with "Fraud," "veins" with "brain."
Internal & Slant Rhymes
Catches the loose rhymes rappers actually use, like "banged" with "slang" or "darkness" with "shark."
Rap Slang Map
Knows "jawn," "Glizzy," "Henny," "K-Dot," "Drizzy," and many more rap-specific words across a wide range of categories.
Ghost Rhymes
Empty lines fade in rotating rhyme suggestions ranked to your last bar and your vibe. Free, no Credits.
Studio Gear
