Software that earns its place in your day.
Ribanix Labs is an independent software studio in Kolkata, India. We build focused tools: one for riders, one for business partners who share books, and one for anyone who works with their voice.
Three products. Each does one thing well.
Every product has its own look and its own home. Pick one to open it.
RevCrank
A free motorcycle ride app
Record every ride, ride as a pack with a live map and push-to-talk voice, and keep talking when the signal drops. A garage for 1,200+ bikes, route planning and crash SOS. No ads.
RibaLedger
Shared, live ledger books
One book for business partners and suppliers. Either side adds entries, the other confirms, and every change is kept in a tamper-evident audit trail. Try the demo with no account.
Mimicore
A private AI voice studio
Clone a voice in seconds, change it live, train your own, turn text into speech in 23 languages and dub video offline. Everything runs on your own PC.
A short list of things we will not compromise on.
Private by default
Your rides stay on your phone, your voice stays on your PC, your books are visible only to the partners in them. We collect only what a feature needs.
Built for real use
We design for a rider in a ghat with no signal and a trader reconciling at night, not for a demo. Features get tested on real devices before we claim them.
Honest about limits
If something is an aid and not a guarantee, or is still a beta, the product says so. Plain language, no dark patterns, no ads in the apps.
