Hey Product Hunt 👋
I'm Luke. I produce beats, and I've worked with a lot of rappers over the years, watching them write. The same problems came up again and again: they couldn't see their own rhyme scheme, they'd pack too many syllables into a bar without catching it, and the notes app on their phone did nothing to help.
So I built RhymeFlux. As you type, your rhymes light up in matching colors, even the near ones that don't land perfectly. Every line shows its syllable count, and a Beat Grid lines your flow up with the beat, so you can spot an overloaded bar before you step in the booth. Tap any word for instant rhymes, swaps, and longer multi-word rhymes, or open the Rhyme Finder to search anything. When you want a push, the AI Co-Writer can draft or rewrite a bar in the vibe you pick. You can record a quick take on any line, play a beat while you write, and run the whole song from a built-in teleprompter.
It's free to start, and it works on web, iOS, and Android, all in sync. I'd love feedback from anyone who writes - what would make your process tighter?

Does the syllable counter handle non-standard flows like triplet patterns or just straight duple time?

@tayfunabik5641 The counter doesn't care what flow you're on, it just counts syllables. So triplets read fine, so does anything else.
Trick for triplets: aim for 12 in a 4/4 bar (4 beats x 3). Count sits at 12, the grid fills that pocket. Straight 16ths would be 16. No mode to flip, you just watch the number

Tried it on a quick verse and the syllable counter plus beat grid actually helped me fix a clumsy bar I’d been stuck on for days. Wish I had this back when I was writing on napkins.

@srabdy7 This is exactly why I built it. That one stubborn bar almost always has a syllable too many, and now you can actually see it. Thanks for running it through a real verse 🙏

Tried it on a quick verse and the syllable counter right next to each line actually kept me honest in a way I didn't expect. The beat grid mapping is a neat touch too.

@elifxsdz Yess, that's the number doing its job. Hard to fool yourself with the count sitting right there. Glad the grid landed too.

the live syllable counter on each line is such a smart touch, makes it way easier to stay on beat without breaking your flow. love that it works the same on mobile too.

@nuray4hh6 Mobile had to work, that's where half the writing happens. Same counter everywhere, synced across web, iOS and Android, so you can start a bar on your phone and finish it on a laptop. Thanks!
