Show HN: VoiceFlow – Sub-second (0.3s-0.6s) voice-to-text built in Rust

Hi HN,

I was frustrated by the lag in Electron-based Whisper wrappers. Most of them feel disconnected from the typing experience because of the 2-5s delay.

I built VoiceFlow to solve this. It’s a native Rust core that targets 0.3s-0.6s latency. The goal is to make voice-to-text feel as instant as typing.

Key features:

Global hotkey [Ctrl+Space] to type into any app (Slack, VS Code, etc.)

Native Rust implementation for performance and low memory footprint

AI-based post-processing for punctuation and style

Privacy-focused: Microphone is only active during the keypress

I'm currently in private beta and looking for feedback, especially on the latency and UX.

I'll be around to answer any technical questions!
