Juno vs Superwhisper

Both keep your voice on your Mac. The difference is what happens after the text lands.

Superwhisper is the careful one. It runs Whisper on your own machine, it works with the wifi off, and its modes let you pair a model with a prompt so the same words can come out as a Slack message in one app and a commit message in another.

Juno agrees with all of that. Transcription is local, audio is never uploaded, and the model that turns speech into text runs on your hardware.

Where the two part company is the ceiling. A Superwhisper mode can rewrite what you said. It cannot go and get anything. Ask for the Q3 invoices to be pulled out of your mail and filed by date, and Superwhisper will write you a beautifully formatted sentence describing the job you still have to do.

Where Superwhisper is the better pick

  • Modes are genuinely well built. If your whole workflow is speaking text in different registers, that is a mature feature with years of polish behind it.
  • There is an iPhone app. Juno has no mobile story at all.
  • It transcribes existing audio and video files. Juno only listens live.
  • Lifetime pricing is an honest offer in a category that has mostly gone to subscriptions.
  • It does one job and does not ask for permission to control your computer.

Where Juno pulls ahead

  • No purchase. The app is free and the source is on GitHub.
  • The same voice trigger can type or act, and you decide which per trigger.
  • It can see the screen, so it can act on what is in front of you rather than only on what you dictated.
  • Wake word listening, so your hands never have to find a key.
  • The CLI exposes the same screen, mouse and keyboard to Claude Code, Cursor and anything else that speaks MCP.

If you already own Superwhisper

Keep it. You paid once and it does its job. The question worth asking is how often you finish a dictation and then spend the next two minutes clicking through the thing you just described. That gap is the entire reason Juno exists, and trying it costs nothing.

Questions people ask

Is Juno's transcription as accurate as Superwhisper's?
Both run Whisper locally, so accuracy comes down to which model size you pick. Juno lets you download larger models the same way. On speed, Superwhisper's bigger local models sit around one to two seconds, and Juno is generally quicker than that on Apple Silicon, though your machine and your model choice decide it.
Does Juno have anything like modes?
Not as saved presets. You ask for what you want instead, which covers the same ground more loosely. If you rely on a dozen tuned modes bound to specific keys, that is a real thing Superwhisper does better today.
Is my audio uploaded?
No, in both apps. Juno transcribes on device. Screenshots go to your chosen model provider only while a task is running, and only if you use the agent at all.
Can I use both?
Yes. Bind them to different keys. Plenty of people keep a dictation app they like and add Juno for the tasks that need doing rather than typing.

Free, and the source is public. macOS 14+.
