For MacOS I haven’t seen any STT app that has faster transcription than Hex (with Parakeet V3), which leverages Apple silicon + FluidAudio:

This is now my standard way to speak to coding agents.
I used to use Handy but Hex is even faster. Last I checked, Handy has stuttering issues but Hex doesn’t.
Not sure what the stuttering issues are...
For my part, I don't need an app that's faster than Handy, and I do like that Handy is Tauri (Rust + web), which means it could be fully cross-platform eventually. It's mostly that the stack is just more hackable for me personally.
