Murmur
Local Mac dictation with optional AI polish
What it does
Murmur is a lightweight macOS voice keyboard. Hold Fn, speak, release, and text appears where your cursor is. Hold Fn + Control to use your speech and selected text as context for AI-polished output. Raw transcription runs locally for privacy, and AI mode sends text, not audio. Use your own API key instead of paying another fixed dictation subscription.

We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
