Muesli

Local-by-default dictation & meeting transcription for macOS On-device speech-to-text by default · Optional OpenAI or OpenRouter dictation · Privacy by default

What is Muesli?

Muesli is a lightweight native macOS app that combines WisprFlow-style dictation and Granola-style meeting transcription in one tool. Dictation and meeting transcription run locally on Apple Silicon by default. Optional hosted dictation sends audio to OpenAI or through OpenRouter to your selected model. Hosted cleanup, Quill, summaries, and hosted Computer Use send the input needed for those features when selected. The experimental on-device Computer Use planner runs with downloaded Gemma models without ChatGPT. iCloud sync transfers text and sync metadata, never audio.

New in 0.8.5

This release also adds six- and twelve-hour calendar windows, hiding individual events from the status-bar menu, easier shortcut-conflict recovery, and improved update-window presentation. Dictation and meeting transcription remain local by default. [Read the full 0.8.5 release notes](docs/release-notes/0.8.5.md).

Dictation

Hold your hotkey (or double-tap for hands-free mode) → speak → release → transcribed text is pasted at your cursor. ~0.13 second latency via Parakeet TDT on the Apple Neural Engine.

By default, dictation uses an on-device model. You can instead opt into OpenAI Speech-to-Text with your own API key, which streams microphone audio directly to OpenAI over a Realtime WebSocket, or connect OpenRouter and explicitly choose a transcription model. OpenRouter dictation sends the completed recording through OpenRouter to the selected upstream model. Muesli retains the local recording only long enough to fall back to a compatible installed on-device model if the hosted request fails; streaming-only models are excluded from fallback.

Quill

Select text and speak an instruction to rewrite it, or ask a question and generate text at the cursor with no selection. Choose your model in Models → Quill. If a required local model is missing or a selected account is signed out, Muesli prompts you to download the model or sign in before use.

Meeting Transcription

Start a meeting recording → Muesli captures your mic (You) and system audio (Others) simultaneously → VAD-driven chunked transcription happens during the meeting at natural speech boundaries → speaker diarization identifies individual remote speakers (Speaker 1, Speaker 2, etc.) → when you stop, the transcript is ready in seconds, not minutes. Generate structured meeting notes via OpenAI or Anthropic API keys, free OpenRouter models, your ChatGPT Plus/Pro subscription, Claude Code, or local Ollama models.
