Y Combinator LaunchFebruary 10, 2026VoiceOS: The Voice OS for Productivity
We're on a mission to turn your voice into 10X productivity across every app.
The problem: Typing sucks
Most people use their keyboard hundreds of times a day — and the costs add up. Every email, every Slack message, every document means translating the thought in your head into keystrokes on a screen. It's a process so ingrained we barely notice how much it slows us down.
- Mental overhead — turning thoughts into typed words
- Time wasted — correcting your typos
- Lost momentum — when context-switching between apps
We've all experienced it: you know exactly what you want to say, but by the time you type it out, rephrase it, fix the typos, and polish the formatting, the original spark has faded. The keyboard — for all its utility — is a bottleneck between your brain and the digital world.
The solution: Voice as the new OS
VoiceOS is a universal voice interface that converts thoughts into polished output — instantly. Instead of typing out every word, you simply speak your intent and VoiceOS handles the rest: formatting, tone, grammar, and context.
Reply instantly
"Ask to reschedule for tomorrow" → replied instantly. No typing, no overthinking.
Better prompting
Turn messy thoughts into perfect prompts for AI tools — effortlessly.
Works everywhere
Works with any app — Slack, Gmail, Notion, ChatGPT, Cursor — with zero setup required.
We're building for a world where AGI is no longer science fiction but an emerging roadmap. In that world, the keyboard won't be the primary way you interact with technology. Your voice will be.
The team: Voice AI Pioneers
Over the past 7 years, Kai and Jonah have built voice AI solutions — from consumer products to Fortune 500 deployments. That experience taught them one thing: voice technology has been held back not by the models, but by the interfaces. The world needed a voice operating system — one designed from the ground up for productivity, not just dictation.
That conviction led them to build VoiceOS and bring it to Y Combinator. Today, they're sharing it with the world.
