Hold Fn, speak, and Megaphone types clean text into any Mac app. Apple’s SpeechAnalyzer transcribes as you talk, while on-device Foundation Models remove fillers, fix self-corrections, adapt to app context, and power inline voice commands. No account, API key, subscription, or server. Free, MIT-licensed, and native to Apple silicon Macs running macOS 26.

Is there any equivalent to this that's possible on Windows?
@pentian sadly windows does not have an NPU so that's a hard one :(
Running everything on-device feels like a long-term advantage if the experience is just as good as cloud tools.
Curious—what convinces people to stick with Megaphone after the first week—privacy, speed, or something else?
@aryan787544 absolutely ! It's likely a mixture of both :) Megaphone is for everyone and Open Source
Absolutely love this, have been using it daily. Any plans to build something like this for iOS?
@alex_crowley6 MLX and foundation models are yet to be ported at the same level + I drive an android haha, but I'll look into it :)
no account or server for a dictation app is genuinely rare, most of them want a login and a subscription before you even test the accuracy. the self-correction cleanup is the feature I'd actually use daily, saying a sentence wrong and just re-saying it instead of manually deleting the messed up part. does it handle a correction that comes a few sentences later, like if you catch a mistake after you've already moved on, or does it only fix corrections said right after the error
Nice one, congrats on the launch. The fact that this is free, local and open source makes it very easy to root for. Dictation apps have somehow become another monthly subscription, even when the Mac can now do most of the work itself. The app-aware formatting sounds especially useful, nice. I’d want a message in Slack to come out differently from a note in Obsidian or a paragraph in a document. The real test for me would be Smart Cleanup. Can you quickly see what it changed or dial it back when it starts making your words sound a bit too polished?
Hey folks, adding to launch day excitement, I'm running an agent loop that looks at the best suggestions in the comments and raises PRs to integrate it into the app 🙌
So drop your best ideas that would make Megaphone perfect for you :)
