Everything You Need
to Write Better Bars.
Every tool that makes writing bars faster, hitting harder, and finishing songs easier. Built for rappers, not coders.
Find Rhymes
Nobody Else Hears.
Most rhyming sites only catch the easy ones like "cat" and "hat." RhymeFlux hears the actual sound of your words and finds deeper rhymes you'd miss on your own. Works for US, UK, Australian, and Canadian English.
Real-Time Rhyme Highlighting
Color-codes every rhyme family in your bars as you type. "Incredible" matches "unforgettable" because it hears what standard dictionaries can't. Pick how strict the rhyme detection is. Five modes: Off, Strict, Rap, Loose, or Everything.
Sound-Based Matching
It ignores spelling and matches on vowel sounds. "Time" rhymes with "Mine," "God" with "Fraud," "veins" with "brain". It hears the way rappers actually say words.
Internal & Slant Rhymes
Spots mini-rhymes hiding inside your lines and catches the loose rhymes rappers actually use, like "banged" with "slang" or "darkness" with "shark."
Rap Slang Map
RhymeFlux knows "jawn," "Glizzy," "Henny," "Bape," "K-Dot," "Drizzy," and many more rap-specific words across 19 categories. It rhymes the way you actually spit.
Stay Perfectly
on Beat.
Rap is math. RhymeFlux counts every syllable in every bar so you can see your rhythm before you ever hit the booth.
Live Syllable Counter
See your syllable count update in real time as you type. It handles acronyms ("FBI" = 3), expands numbers ("100" = 2, "99" = 4), and ignores ad-libs in parentheses automatically.
Beat Grid
A 16-slot visual grid that shows where your syllables fall on a 4/4 beat. See if your flow is too packed, too empty, or right in the pocket.
Rhythm Shift Warning
If your syllable count jumps by more than 5 between lines, the app pulses a soft warning so you can hear that your rhythm just shifted.
Color-Coded Flow
Each line gets a color based on how packed it is. Light flow, dense flow, or overflow. You can spot a stuffed bar at a glance.
Pull up in the foreign, gang slidin' on a wave
Need a Rhyme?
Get 300 of Them.
Type any word. Get up to 300 rhymes from RhymeFlux, sorted by how many syllables they have. Tap one and it lands right in the line you're writing.
Grouped by Syllable Count
Need a 1-syllable end-rhyme? Or a multi for a punchline? Each result group splits by syllable count so you grab the right kind of rhyme for your flow.
Tap to Drop It In
See a rhyme you like? Tap it. It drops straight into the bar you were writing. No copy-paste, no leaving the canvas.
AI Backup If You Need It
If the local matches run dry, an "Ask AI" button pulls more vibe-tuned rhymes from the AI. Costs 1 token, but only when you actually want it.
Empty Lines That
Whisper Back.
Stare at a blank line and RhymeFlux quietly suggests rhymes for the next bar, right there on the canvas. Read them. Steal one. Or use them as a launchpad to write your own.
Free, Forever
No AI tokens used. The same logic that lights up your typed bars is the one suggesting rhymes here.
Vibe-Aware
Suggestions are ranked against your last bar and your active vibe. Trap pulls trap-friendly rhymes. Drill pulls darker ones.
Always Cycling
Every few seconds, a new suggestion fades in. Don't like one? Wait. Another's coming.
Stays Out of the Way
Faint italic text, never loud or in-your-face. They're hints, not commands. Type over them whenever you want.
Kill Writer's Block.
Instantly.
This isn't a generic chatbot. It reads your bars, matches your vibe, and hands you options. You stay in charge. Built on Gemini 3 Flash with custom rap profiles.
Write or Rewrite
Empty line? The AI writes a bar for you. Three ways: finish the rhyme you started, try a new rhyme pattern, or match the same syllable count as the line above. Already wrote one? It can rewrite it harder.
Pick Your Vibe
Set the style before you write. Trap = luxury brands and triplet flows. Drill = dark energy and choppy bars. Lyrical = layered rhymes and big metaphors. Melodic = singable hooks and emotional vibes.
Tap-Any-Word Suggestions
Tap any word. A popup opens with three columns. Rhymes from RhymeFlux (free, always). Word swaps that fit your vibe. Multi-word rhyme phrases that replace the whole tail of the bar.
God Prompt
Stuck on a whole verse? The AI writes 4 to 5 bars in one shot. It reads the other parts of your song so the new bars fit the story, and figures out on its own if it's a verse, hook, bridge, or outro.

Record a Take
Right on the Bar.
Hit record on any line and lay down a take while the words are fresh. Every take stays attached to the bar you wrote it on. No more 50 voice memos named "New Recording 4."
Stack Takes Per Line
Pro keeps every take you record on a bar. Try the same line ten different ways. Compare them in seconds.
Auto-Play Your Favorite
Mark a take as Active and it plays back the moment you focus that line. Like a vocal guide for the next bar.
Live Timer & Scrubber
See how long you've been recording. Drag the playback bar to any moment. Rename takes so you know which is which.

Your Phone

Big, Adjustable Text

Auto-Scroll at Your Tempo
Set the scroll speed in BPM to match your beat. The lyrics roll past you exactly when you need them.

Late nights in the lab,

Save Both Punchlines.
Pick the One That Hits.
Wrote a line you love but want to try another angle? Tap the sparkle. The AI saves a polished draft next to your original on the same line. Flip between them in the booth and roll with whichever one hits hardest.
Drafts Stack Per Line
Each line keeps its own stack of drafts. Open the "1/2" dropdown next to the bar to see all the versions you've tried.
One Tap to Switch
Use the arrow buttons or pick from the dropdown. The bar updates instantly. Read both out loud before you commit.
Never Lose the First One
Pick the polished draft and your original stays in the stack. Change your mind later? Switch back in one tap.
Stack As Many As You Want
Try three angles, six, ten. Cycle through every draft when you're ready to lock in the final bar.
