WhatA privacy-first voice SDK that lets developers add hold-to-talk speech input to any local AI agent or coding workflow without data leaving the machine.
SignalThe builder describes already using local speech-to-text as a voice interface for their own AI agents, suggesting a growing need for a standardized local voice layer that plugs into the emerging ecosystem of local LLMs, coding assistants, and automation tools.
Why NowLocal speech models like Whisper and Parakeet have reached usable accuracy on consumer hardware, and the explosion of local AI agents (Claude Code, Codex, etc.) creates demand for a voice input layer that matches their privacy guarantees.
MarketDevelopers and power users running local AI toolchains; adjacent to the $2B+ voice API market (Deepgram, AssemblyAI) but positioned as the self-hosted alternative. Key gap: no one owns the 'local voice SDK for agents' category yet.
MoatIntegration depth — becoming the default voice bridge embedded across multiple agent frameworks creates switching costs and a plugin ecosystem.
