Hex is a desktop push-to-talk app that turns raw voice dictation into polished AI prompts. Hold a hotkey and speak — your words are transcribed locally in real time, then refined by Claude and ready to paste anywhere.
I wanted to talk to my computer and have it understand what I meant, not just what I said. Voice dictation gives you a wall of filler words and half-finished thoughts. I needed something that would take that raw stream and shape it into a clear, usable prompt — instantly.
All speech recognition runs locally on your machine using Whisper. No audio ever leaves your device — only the final transcribed text is sent to Claude for refinement.
Choose between OpenAI Whisper and NVIDIA Parakeet models — from 75 MB lightweight to 3 GB multilingual. All run on-device.
Switch between Prompt, Message, and Dictation modes — or create custom modes with your own system prompts and templates.
Fully customizable hotkeys for push-to-talk, append mode, paste, and mode cycling. Works from any app.
Tiny footprint — sits in your menu bar, launches instantly, no dock icon or window management.
