After a one-time setup, it works with no internet at all.
Fast, local, free.
Dictation for Mac that cleans up after you. Hold a key, say it however it comes out, and let go. The ums and false starts are gone, and clean text appears wherever you type.
Your words appear here as you say them.

Talk for up to 60 seconds here. For this web demo the clip goes to a speech service and is not stored. The Mac app listens for up to 20 minutes, or 60 with Pro, and does all of this on your Mac. Privacy
Rambleproof lives in your menu bar. There is no window to open, just one shortcut that works wherever you can type. Try it in the demo above.
Works in any app. A small recording indicator appears at the right edge of your screen, so you know it is listening.
Restart a sentence. Change your mind halfway. Say um. Keep going until the thought is out.
Clean text appears where your cursor is. If you switched windows or are in a password field, it goes to your clipboard instead, and the indicator tells you.
It takes out the filler and keeps what you meant. Before it types anything, Rambleproof checks that no number and no “not” changed. If one did, you get a simpler cleanup of your own words instead. Turn the level up for more polish.
okay so um the thing is I think we should we should push the launch to Monday, no wait, Tuesday because uh legal hasn't signed off on the on the terms page yet and I told them we'd have a a real timeline by Thursday

Every word in the result is a word you said.
Everything runs on your Mac. The cloud is opt-in, with your own key.

Sign in once on each Mac. After that, the free app keeps working on its own.
Audio and text stay on your Mac.
Want a cloud model? Add your own OpenAI, OpenRouter or Gemini key. Until you do, nothing leaves your Mac.
Add names and terms once, and Rambleproof keeps their spelling. Added words are protected from cleanup. If one keeps coming out wrong, add what Rambleproof hears as a Heard as spelling and it swaps in yours. Add up to 50 terms on Free, unlimited on Pro. Imported words always keep working.

From each app's pricing page, 1 September 2026. The long comparisons, with every source: Wispr Flow and Superwhisper.
Coming from Wispr Flow? The same clean text, made on your Mac, for $96 a year instead of $144.
Coming from Superwhisper? Parakeet on the free plan, with nothing to configure.
Parakeet, the speech engine family Rambleproof runs, makes fewer mistakes than Whisper large-v3 on the same audio. Shown next to Wispr Flow and Apple Dictation, with text in about a second. How we measured
19% fewer words wrongwith Parakeet v2 than with Whisper large-v3, on the same audio. These are speech engines, not apps.
Same audio, independent leaderboard
* Measured elsewhere, on different audio
Lower is better. Rows marked * or † were measured elsewhere. Parakeet v2 makes about 14 fewer word errors per thousand than Whisper large-v3 on an independent leaderboard. It compares two engines, not two apps. Superwhisper can run Parakeet too, and Rambleproof's default English model is Parakeet Unified, a different configuration. Wispr Flow and Apple come from other sources.
Sources: Open ASR Leaderboard, English short-form. * Scott, Liang, Wassink and Levow, University of Washington (arXiv:2510.22495).
The leaderboard measures speech engines, not whole apps, averaged over 8 datasets: AMI, Earnings22, GigaSpeech, LibriSpeech clean, LibriSpeech other, SPGISpeech, TED-LIUM v3, VoxPopuli. Before 1.0.9, Rambleproof's own end-to-end time was 1.32s median over 37 dictations (key release to cleaned text at the cursor, MacBook Air M4, macOS 26.5.1); 1.0.9 streams transcription while you talk and brings that to about 1 second.
| Tool | What was measured | Accuracy | Measured by |

| Whisper large-v3 | Whisper large-v3 | 7.44% | Open ASR Leaderboard, English short-form |

Dictation is unlimited on every plan. Free includes 15,000 AI-cleaned words a week. That is about an hour and a half of talking. After that, basic cleanup takes over until Monday. Dictation never stops.

One payment, yours to keep. Managed cloud and cloud sync are not included. Your API provider bills your own-key usage separately.
Free account, no card. macOS 15 or later, including 27 (26 or later recommended) on Apple silicon (M1 or later).
Sign in with Google or your email. The download starts right away.
Drag Rambleproof into Applications and open it.
Click Link account, then allow Microphone and Accessibility. Link account asks you to type a short code the app shows, once. Microphone lets it hear you; Accessibility (Device Control and Data Access on macOS 27) lets it type at your cursor. It never types into password fields.
Wait for the one-time model download, then press Right Option anywhere, talk, and press it again. Holding control and Z works too.
Something else? Write to us.
Any Mac with Apple silicon (M1 or later) on macOS 15 or later, including macOS 26 Tahoe and macOS 27 Golden Gate. macOS 26 or later is recommended because it adds optional Apple models. Intel Macs and macOS 13 or 14 are not supported. Check under Apple menu, About This Mac.
It works anywhere you can type: email, notes, chat, docs, your browser and AI tools. A few web editors and terminals behave differently. If no text field is selected, your words are copied so you can paste them yourself, and it never types into a password field.
Nothing stops. You keep dictating as much as you like, and until Monday the cleanup is basic: fillers and punctuation, without the AI rewrite. The app shows when that happens. Pro has no weekly limit. Installations from before version 1.1.1 keep 20,000 AI-cleaned words a week.
Two things. Microphone, so it can hear you while you hold the shortcut. Accessibility (called Device Control and Data Access on macOS 27), so it can type at your cursor and avoid password fields. Nothing else.
Built-in dictation types every word as it hears it, ums included. Rambleproof waits until you let go, cleans up the whole thought, checks that your meaning survived, and then types it once.
No. The built-in microphone, AirPods or a USB microphone all work. Rambleproof picks the best one and switches to another if one goes silent mid-sentence.
English is the language we have tested and recommend. Other languages can work, but we only make claims about what we have measured.
If you are on a Mac and want your words to stay on it, yes. Wispr Flow sends your audio to the cloud and works on more devices. Superwhisper runs locally with many models to choose from. Rambleproof runs on your Mac with nothing to configure and checks the cleaned text against what you said. We build it, so read the full comparisons too.
Yes. After the one-time setup, speech recognition and cleanup run entirely on your Mac with no internet. Only the optional cloud models, which you switch on with your own key, send anything off your Mac.
Nothing you need to do. Rambleproof keeps your settings and permissions. The first dictation after a macOS update can take up to a minute while the speech model is prepared once, and after an upgrade to macOS 26 or 27 the optional Apple models appear in Settings.
