Three steps, all on your machine

From a live meeting to a shareable summary, locally.

  1. Step 1

    Record

    Capture microphone and system audio together, mixed locally. Nothing is uploaded.

  2. Step 2

    Transcribe

    Whisper and Parakeet models run on-device, GPU-accelerated, in real time.

  3. Step 3

    Summarize

    Get decisions and action items from a local LLM, or a cloud provider you choose.

See it while you talk

A live transcript as the meeting happens, and a structured summary the moment it ends.

Live transcription while you take notes.

Decisions and action items, generated locally.

Your conversations stay yours

Meeting audio, transcripts, and summaries are processed and stored on your device. muesly is built for people whose conversations can't live on someone else's servers.

Anonymized usage analytics is opt-out, and cloud LLM summaries are opt-in only if you configure a provider. Read the privacy policy.

Built for real meetings

Everything you need to capture a conversation, nothing that phones home.

Local-first transcription

Whisper and Parakeet models run on-device with GPU acceleration on Apple Silicon, CUDA, and Vulkan. No cloud round-trip, no usage caps.

Summaries your way

A local LLM by default, or bring Ollama, Claude, Groq, OpenRouter, or any OpenAI-compatible endpoint.

Works everywhere

Native builds for macOS, Windows, and Linux.

Professional audio capture

Microphone and system audio mixed with smart ducking and clipping prevention, so every voice is clear.

Questions, answered

Is muesly really free?
Yes. muesly is free and open source under the MIT license. There is no paid tier and no account.
Where does my data go?
Recordings, transcripts, and summaries are processed and stored on your device. Nothing is uploaded unless you explicitly configure a cloud LLM provider for summaries.
Can I verify the privacy claims?
Yes. The full source is on GitHub under the MIT license, so you or your security team can read the code and watch the network yourself.
Does it work with Zoom, Teams, and Google Meet?
Yes. muesly captures system audio alongside your microphone, so it works with any call. No bot joins the meeting.
Is there a meeting bot?
No. muesly records locally from your own audio. Nothing joins your call and no participant sees a recorder.
Do I need an account?
No account, no sign-up, no email. Download and run.
What analytics does muesly collect?
Official builds include anonymized, opt-out usage analytics to help fix bugs and improve performance. It never includes meeting content. You can disable it in settings, and builds compiled without an analytics key have it off entirely.
Which platforms are supported?
