About Me
→Hi, I'm Rounak!
I care about the small details that make software feel alive — the half-second of latency you shave off, the animation that lands just right, the interface that explains itself. I work mostly across product and design, building voice AI at smallest.ai.
Playground
→Text → Speech. Type anything and hear it in a real smallest.ai voice.
Speech → Text. Tap record, talk, and Pulse transcribes what you said.
Speech → Speech. A live voice agent — talk to Ask Rounak and it answers out loud, in real time. Full-duplex, so you can talk over it.
Discoveries are out there, waiting to be made. Why not by you?
