MightyMouse vs Superwhisper
Both let you talk to your Mac instead of typing. The difference is what happens after the words land.
Superwhisper is a dictation app, and a good one. You hold a key, speak, and your words appear wherever the cursor is. If that is all you need, it does the job.
MightyMouse starts in the same place and keeps going. The words can become an action instead of just text: rewrite the paragraph you selected, answer a question about the file you are looking at, or run something. It also turns your iPhone into a trackpad and microphone for the Mac, which is a different job entirely.

Where Superwhisper is the better pick
We would rather you chose the right tool than our tool. Superwhisper wins if you are on Windows, if you want dictation on your iPhone as a standalone app, or if you want a one-time payment and never want to think about it again. MightyMouse is macOS only, and there is no lifetime licence for it today.
Where MightyMouse is the better pick
Pick MightyMouse if the words are supposed to do something. Select an awkward email and say "make this warmer and shorter" and it is replaced in place, in the app you were already in. Point at a screen you do not understand and ask what is wrong with it. That is a different job from typing by voice, and it is the one we built for.
The second reason is the phone. Your iPhone becomes a trackpad and a microphone for the Mac, so you can start something at the desk and keep steering it from the sofa. No dictation app does this, because it is not a dictation feature.
Both run on your own machine
This is worth saying plainly because it is the thing people care about most and the thing marketing pages are vaguest about. MightyMouse transcribes with Whisper on your Mac. The audio does not go anywhere. Superwhisper also offers local models, and cloud models if you want them. On this point the two are closer to each other than either is to the cloud-only tools - Wispr Flow sends your audio to its servers by design.
Free with the AI account you already have.
macOS, Apple Silicon and Intel. No card to try it.
Common questions
Do I need an AI subscription?
No. Connect a Claude, Codex, Gemini or OpenCode account you already pay for and MightyMouse costs nothing. Have none? Sign up and use the built in option, no card needed. Voice transcription is free either way because it runs on your Mac.
Can I use both?
Yes, though you will probably want to give them different hotkeys so they do not both fire at once.
Is my audio uploaded?
No. Transcription is local Whisper. What does leave your Mac is whatever you send to your AI provider when you ask a question - the same as if you had typed it into their app yourself. Details are in the privacy policy.
