The Pro Studio Breakdown

Everything that makes RhymeFlux the pro writing studio for serious artists.

Writing Studio

Rhyme Finder

Search any word and get up to 300 rhymes, grouped by syllable count. Tap to drop one into your line.

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."

576-Word Slang Map

Knows "jawn," "Glizzy," "Henny," "K-Dot," "Drizzy," and 576 more rap-specific words across 19 categories.

Ghost Rhymes

Empty lines fade in rotating rhyme words ranked against your last bar and active vibe. Free, no AI tokens.

Studio Gear

Airplane Mode Studio

Keep writing on planes, in the booth, or at the venue. Zero Wi-Fi needed.

Line-by-Line Recording

Record your takes directly on each bar. Keep unlimited audio stacks per line.

Full Song View

See all your verses and hooks in one long list — perfect for a top-to-bottom performance run.

Drag-and-Drop Structure

Drag whole blocks of bars and verses to fine-tune your song structure in one click.

Built-In Beat Player

Loop YouTube beats or drop in your own MP3 / WAV / M4A files. Mobile-friendly — no YouTube Premium needed.

AI Co-Writer

AI Suggestions Popup

Tap any word — a 3-column popup opens with rhymes, vibe-tuned word swaps, and multi-syllable phrases.

Rewrite Mode

Hit Sparkle on any line to remix it into a Glitch Version. Swipe between Organic and Glitch to pick the winner.

God Prompt

Stuck on a whole verse? Generate a 4–5 bar section in one shot, tuned to your active vibe.

Generate Next Bar

Three modes for empty lines: Complete It (matches your scheme), Switch Up (new scheme), or Rhythm Match (mirrors syllable count).

4 Vibe Profiles

Set your style: Trap, Drill, Lyrical, or Melodic. The AI writes bars that actually sound like the genre.

* Keep writing for 7 days with no Wi-Fi. Everything syncs back when you're online.

Pricing Questions

Can I try RhymeFlux before paying?
Yes. The Starter plan is 100% free forever. It gives you 3 active songs, 3 sections per song, and 15 AI uses every 30 days so you can test the full studio. All your bars cloud-sync across mobile and desktop. No credit card needed to start.
What is the "7-Day Offline Vault"?
Studios and planes don't always have Wi-Fi. The Offline Vault saves your work to your device so you can keep writing for up to 7 days with no internet. Everything syncs back the moment you're online.
Can I cancel or switch plans?
Yes. You can upgrade from Monthly to Annual at any time to save 45%. If you cancel, you keep Pro access until your billing period ends.
Is my data secure?
Your lyrics belong to you. They live in your private account, and we never use what you write to train AI. The analytics we run only tracks basic stuff like sign-ins and saves — nobody on our side reads your bars.
Does RhymeFlux work in other languages?
The rhyme highlighting is built for English - US, UK, Australian, and Canadian accents. It won't catch rhymes accurately in Spanish, French, or other languages. The AI Co-Writer can brainstorm in multiple languages, but for full rhyme scanning and syllable counting, English gives you the best results.
