Drop in an interview, a meeting or a lecture. Murko writes down who said what, makes a short summary with tasks, and lets you fix every line. Nothing is uploaded anywhere.

Summary and tasks

A short summary, decisions, tasks and open questions, written by a text model that also runs on your Mac.

Fix it in place

Click a line to hear it. Correct a word, split a line in two, join it to the one above, or change who is speaking.

Many languages

Ukrainian and English are detected by themselves; pick any other language from the list.

UK · EN · and many more

Choose the engine

Parakeet for speed, Whisper Large for care, or Automatic to let Murko pick. Add your own MLX model in Settings.

Privacy

Your recordings never leave your Mac

Interviews, medical notes, business calls: what people say in a recording is private. Murko is built so that it stays with you.

Everything runs on your Mac

Speech recognition (Parakeet and Whisper), speaker separation (Senko) and the summary model (Gemma) all run on your own computer. No file is uploaded, ever.

Offline after setup

The internet is used once, during installation, to download the models. After that you can transcribe with Wi‑Fi switched off.

No account, no tracking

Murko has no sign-up, no analytics and no ads. It does not send usage data anywhere.

Your files, your folder

Transcripts are ordinary files in Documents/CallsRawFiles (or a folder you choose). Delete a transcript and it goes to the Trash like any other file.

Originals are never changed

Murko works on a copy of your recording. The file you dropped in stays exactly as it was.

Easy to remove

The uninstaller moves Murko and its models to the Trash and keeps your transcripts, so you decide what happens to them.

Languages

Speak your language

Murko transcribes these languages, each one checked in testing:

UkrainianEnglishPolishGermanFrenchSpanishItalianPortugueseDutchCzechSlovakRomanianHungarianBulgarianCroatianSlovenianGreekSwedishDanishFinnishLithuanianTurkishHebrewArabicHindiChineseJapaneseKorean

The app itself has an interface in English, Ukrainian, Chinese, Hindi, Spanish and Arabic.

How to install

  1. Open the downloaded Murko-Transcriber-1.0.zip. A folder appears.
  2. Double-click Install Murko Transcriber.command. macOS asks you to confirm once:
    macOS 15 or newer: click Done in the message, open System Settings › Privacy & Security, scroll down, click Open Anyway and enter your password.
    macOS 14: right-click the file, choose Open, then click Open.
  3. A Terminal window shows the progress. It installs the tools and downloads the models. If it asks for your password, type your Mac password (the letters stay invisible). Leave it open until it says “All done!”.
  4. Open Murko Transcriber from your Applications folder and drop in your first recording.
Why the warning? Murko is a free app made by an independent developer and is not registered with Apple’s paid notarisation service, so macOS asks you to confirm once.
Questions

Good to know

Does Murko send my audio to a server?

No. Everything runs on your Mac: speech recognition (Parakeet and Whisper via Apple’s MLX), speaker separation and the summary model (Gemma, run by Ollama). The internet is used only to download these during installation.

How long does a transcription take?

It depends on the Mac and the model: Parakeet is the fastest, Whisper Large is the most careful and several times slower. The summary and text polishing add extra time; tick “Text only” to skip them.

Something went wrong during installation. What now?

Run the installer again: it skips the finished steps and continues where it stopped. The full log is in ~/Library/Logs/MurkoTranscriberInstall.log.

Which files can I use?

Most audio and video files: m4a, mp3, wav, aac, flac, ogg, opus, aiff, mp4, mov, mkv and webm.

Where are my transcripts?

In Documents/CallsRawFiles. Each recording gets a folder with Transcript.txt and Summary.md. You can choose another folder in Settings.

How do I remove Murko?

Run Uninstall Murko Transcriber.command from the same zip. It removes the app and its tools; your transcripts stay where they are.
