MightyMouse vs Granola
These two get compared a lot, and they are mostly built for different jobs. Worth knowing which one you actually want before you pay for either.
Granola listens to your meetings and writes them up. No bot joins the call - it captures the audio from your computer, sends it away to be transcribed, and gives you back notes you can read afterwards. If your problem is "I take bad notes in calls", Granola is aimed squarely at you and MightyMouse is not.
MightyMouse is a voice and AI layer for the whole Mac. Hold a key anywhere and talk, and the words land at your cursor - in an email, a doc, a terminal. Select something and have it rewritten or explained in place. It has no meeting-notes feature and does not try to run your calls.
So the honest framing is: Granola for meetings, MightyMouse for everything else. Where they genuinely compete is on two questions - where your audio is processed, and whether you want a tool that only works when a meeting is happening.

Where Granola is the better pick
If you are in calls all day and want them written up, use Granola. MightyMouse does not do meeting notes at all - no summaries, no transcripts of a call, no action items. That is not a gap we plan to close, it is a different product.
Granola also runs on Windows, Android and an Apple Watch. MightyMouse is macOS with an iPhone remote, and that is it.
Where MightyMouse is the better pick
Your audio stays on your Mac. Granola captures locally but transcribes in the cloud - your meeting audio goes to third-party transcription services and the transcripts are stored on servers in the US. MightyMouse transcribes with Whisper on your machine, so nothing is sent anywhere. If you work under an NDA, or with patients or clients, that difference is the whole decision.
It works the other 90% of the day. Meetings are a small slice of the time you spend typing. MightyMouse is there for the emails, the messages, the docs and the code in between.
Your notes do not expire. Granola's free tier keeps your history but locks you out of anything older than 30 days until you pay. MightyMouse keeps its history locally on your Mac, and it stays yours.
Can you use both?
Yes, and plenty of people would want to - Granola for the calls, MightyMouse for the rest. They do not overlap enough to conflict. The one thing to decide is whether you are comfortable with meeting audio going to the cloud, because that part is not optional in Granola.
Free local transcription, all day, not just in meetings.
macOS, Apple Silicon and Intel. No card to try it.
Common questions
Does MightyMouse take meeting notes?
No. It has no meeting-notes feature. If that is what you need, Granola or a dedicated notetaker is the right tool.
Does Granola process audio on my device?
It captures on your device and transcribes in the cloud. The audio is sent to third-party transcription services and the resulting transcripts are stored on servers in the United States. MightyMouse transcribes on your Mac, so the audio does not leave it.
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.
