Murmur vs Nerd Dictation
Different tools, same offline-first philosophy.
Nerd Dictation is a beloved CLI tool that pioneered accessible voice dictation on Linux using VOSK. Murmur shares that offline-first philosophy but takes a different approach — whisper.cpp for the engine, Rust/Tauri for the stack, and a floating desktop widget for the UI. Both are free and open source.

Where Murmur differs
Whisper engine
Murmur uses whisper.cpp which generally offers higher accuracy than VOSK, especially for technical vocabulary and longer phrases.
Visual interface
The Comm Badge provides visual feedback — waveform display, status LEDs, recording state. Useful if you prefer a GUI over CLI.
Single binary install
Download the AppImage and run. Configuration through a visual settings panel rather than config files.
Pro features coming
Cloud STT for speed, LLM text cleanup, multi-language. Plus a CLI mode for those who prefer the terminal.
