Megaphone dictation alternative
Megaphone is the stronger general recommendation for many compatible Mac users: it is free, MIT licensed, and combines Apple SpeechAnalyzer streaming transcription with on-device cleanup, a personal Dictionary, app context, voice macros, and inline “Hey Megaphone” instructions. IraVoice is the narrower commercial choice for people who specifically value a notarized installer and a review-first Voice-to-Spec artifact with guarded Codex or Claude Code handoff.
Side by side
A factual comparison of the current product boundaries. Follow the source links below for the latest competitor details.
| Factor | IraVoice | Megaphone |
|---|---|---|
| Price and license | $50 once after the 14-day full trial; commercial proprietary app | Free and MIT licensed, with public source code |
| Mac requirements | macOS 26+ on an Apple-silicon Mac | macOS 26+ on Apple silicon |
| Speech and cleanup | Local speech recognition plus supported on-device Apple formatting in two fixed modes | Streaming Apple SpeechAnalyzer transcription plus on-device Foundation Models cleanup, with deterministic Basic cleanup as fallback |
| Languages | Nine English regional speech choices | Multiple Apple on-device speech languages; the current product site lists 30 locale choices |
| Personalization and context | Fixed Dictate and Voice-to-Spec modes; optional local repository context only inside Voice-to-Spec | Personal Dictionary, automatic learning, JSON import or export, recent-text context, and active app or window-title context processed locally |
| Workflow | Dictate plus Voice-to-Spec Markdown that can be reviewed before guarded Codex or Claude Code handoff | General cursor dictation, hold or toggle activation, voice macros, and “Hey Megaphone” generation or rewriting |
| Saved audio and video | Does not transcribe imported files | The reviewed first-party product workflow documents live dictation, not a saved-file transcription feature |
| Installation trust | Developer ID signed, Apple-notarized DMG with Gatekeeper verification, plus a Homebrew cask | Signed DMG, but the publisher says it is not notarized and may require clearing quarantine or choosing Open Anyway; source builds are available |
| Accounts and network | No account for the trial; speech stays local; paid use performs a Gumroad license check | No account, subscription, transcription API, API key, or Megaphone server; first-use Apple speech-model download still applies |

Questions
Yes. Megaphone’s official repository publishes the app under the MIT license and distributes a free DMG. IraVoice has a full 14-day trial but costs $50 once for continued use.
Megaphone documents on-device Apple SpeechAnalyzer transcription and on-device Foundation Models cleanup with no product server or API key. The selected Apple speech model downloads on first use, and Apple Intelligence setup can affect Smart Cleanup; deterministic Basic cleanup remains available.
This page does not claim that. Both document local speech paths. Megaphone has inspectable MIT source and no product server; IraVoice publishes a narrower architecture and a notarized binary. Verify the current build, active features, model setup, and destination app for sensitive use.
No. IraVoice is free only during its 14-day trial and then costs $50 once. Choose it for its notarized distribution or review-first Voice-to-Spec workflow, not as a permanent-free substitute.
Megaphone is broader for dictating in terminals, using recent text or app context, voice macros, and inline local instructions. IraVoice is narrower but more explicit about converting rough speech into a reviewable Markdown brief before a guarded Codex or Claude Code handoff.
Yes. Its current official site and release documentation require macOS 26 Tahoe or later on Apple silicon because the app uses Apple SpeechAnalyzer.
macOS 26+ · Apple-silicon
Test the notarized Dictate and Voice-to-Spec workflows for 14 days with no card or account, then keep Megaphone if its broader free feature set already fits.
