Thoughts move fast.
Muffin keeps up.

A simple flow from the first sentence to something you can use.

01 / CAPTURE

Just start talking.

Record from the app or menu bar. Muffin saves the audio directly to your Mac.

02 / TRANSCRIBE

See it take shape.

Apple’s on-device speech recognition turns your voice into an editable transcript.

03 / USE IT

Leave with clarity.

Generate a summary, meeting notes, or action items with the model you choose.

The useful part comes next.

A voice note can be a thought to remember, a meeting to revisit, or a list of things to do. Choose what you need.

  • Confirm the timing with Maya.
  • Book a table for six.
  • Collect the cake before dinner.

The details.

Where are my recordings saved?

In your Mac’s Application Support folder, as audio, transcript, metadata, and generated output files. The files are yours to copy or back up.

Does transcription need an internet connection?

No. Transcription uses Apple’s on-device Speech framework. Generated notes use the provider you select; Apple Intelligence and Ollama can run locally, while OpenRouter uses a network connection.

What Mac do I need?

Muffin requires macOS 26 or later, plus microphone and Speech Recognition permissions. Some generation options depend on the model provider you choose.

Is there a subscription or an account?

Muffin needs no account and has no subscription. If you choose a paid cloud model through OpenRouter, that provider may charge for its use.

Keep the thought.
Make it count.

Start with your voice. End with notes you can use and files you can keep.
