MacWhisper vs Rambleproof
Both run on your Mac and neither sends your audio anywhere by default. They are built for different jobs: MacWhisper started as a file transcription app and grew dictation, Rambleproof only does dictation and spends its effort on what happens after the words come back.
By The Rambleproof team. Facts checked . We make Rambleproof, so read this as an editorial comparison with a stake in the outcome, not a neutral review.
The short version
Choose MacWhisper if you have audio files to turn into text: interviews, lectures, meetings, a season of video that needs subtitles. That is what it was built for and it is very good at it. Choose Rambleproof if you never touch a file and just want to talk instead of typing, in whatever app is in front of you, and you want the cleaned text checked against what you actually said before it lands.
They overlap in one place: both offer system-wide dictation on the Mac with local models. If that is the only feature you want, the question is whether you would rather pay once for a large toolbox or use a free tier that is built around the dictation path alone.
What MacWhisper publishes
MacWhisper is made by Jordi Bruin and sold through Gumroad, where it carries over 2,500 ratings. Its feature list describes recording and transcribing audio files, a transcript editor with speaker search, automatic meeting recording in Zoom, Teams, Webex, Skype, Chime and Discord, subtitle export to .srt and .vtt, and exports to csv, docx, pdf, markdown and html. It states that all transcription is done on your device and that no data leaves your machine. There is an iPhone and iPad app as well as the Mac one.
It also lists system-wide dictation with Whisper, described as a replacement for Apple's own dictation. Pro adds Parakeet v2 and v3 on M-series Macs, automatic speaker recognition, batch transcription, a command line interface, Notion, Obsidian, Zapier, Make and n8n integrations, YouTube transcription, realtime captions with live translation, watch folders, and optional cloud transcription through OpenAI, ElevenLabs, Deepgram, Groq and Gladia. Pro's dictation mode can apply automatic spelling, punctuation and grammar improvement, which the page notes requires an AI service to be set up.
MacWhisper is free to download. Pro is a one-time €65 personal licence on its official Gumroad page, with volume licences at €269 for five, €490 for ten, €899 for twenty and €2,199 for fifty. Prices are listed in euros and the dollar amount shown at checkout moves with the exchange rate.
What Rambleproof publishes
Rambleproof is built only for Apple Silicon Macs on macOS 26, and it does one thing: hold the shortcut, speak, release, and the cleaned text appears at your cursor. There is no file import, no transcript editor, no subtitle export and no meeting recorder. Transcription runs on the Neural Engine and cleanup runs either as a local model or as deterministic rules, so the default path needs no network.
The part it spends its effort on is what happens between the transcript and your cursor. Cleanup output is checked against the transcript before insertion, and a change that fails that check is rejected in favour of a safer result rather than pasted. Insertion looks at where the text is going: a different app, a different window, a password field or a control that does not take text becomes a clipboard copy instead of a paste. Unlimited raw local dictation forever, with 20,000 AI-cleaned words each week and deterministic cleanup after that. No app account is required.
Side by side
| MacWhisper | Rambleproof | |
|---|---|---|
| Built for | Transcribing audio and video files | Push-to-talk dictation only |
| Platforms | Mac, iPhone, iPad | Apple Silicon Mac, macOS 26 |
| Where audio is processed | On device, with optional cloud providers in Pro | On device, with optional bring-your-own-key routes |
| System-wide dictation | Yes | Yes, and it is the whole product |
| File transcription | Yes, including batch and watch folders | No |
| Subtitles and exports | .srt, .vtt, csv, docx, pdf, markdown, html | No |
| Cleanup checked before it is inserted | Not described | Yes, with a safer fallback when a change is rejected |
| Refuses to paste into a password field | Not described | Yes, it copies instead |
| Price | Free, Pro €65 once | Free forever, Pro $9.99 monthly or $59 annually, Lifetime $99 founding then $149 |
Rows marked “not described” mean the vendor's own pages do not describe that behaviour. That is not the same as the behaviour being absent, and we have not tested it. We only claim what a vendor publishes about itself.
Where the two actually differ
The honest difference is scope, not quality. MacWhisper is a large, mature toolbox with years of features behind it, and dictation is one item on a long list. Rambleproof has a much shorter list because the list is the point: the entire product is the path from holding a key to text at your cursor, which is why it spends its attention on the two places that path can go wrong. Cleanup can quietly change a number, a name or a negation. Insertion can put your text in the wrong window.
The second real difference is what you pay and when. MacWhisper Pro is one payment and you own it. Rambleproof's Free tier keeps unlimited raw local dictation forever with a weekly allowance of AI cleanup, so the dictation path costs nothing indefinitely, and paying is about removing that weekly limit rather than unlocking dictation itself.
How the models compare
Both apps can run Parakeet on Apple Silicon, so on the transcription step they are drawing from the same well. The chart below is our own measurement of the engines, published with the method and the clips it used.
Accuracy and speed, with every number's source attached
- Rambleproof
- Other tools
Over a thousand spoken words, the engine Rambleproof runs gets about 14 more of them right than the engine Superwhisper runs by default. Wispr Flow and Apple have never been put through that benchmark, so they appear below it against whatever was actually run on them.
What the marked rows mean, the sources, and the numbers as a table
- *Not the same test as the unmarked bars: different audio, in a different year. Wispr Flow 8.7% is published by Superwhisper, a direct competitor, and another rival puts it at 6.2%. Apple is the University of Washington's figure for single words read aloud, measured in 2022: 14% for the best-served speaker group, 24% for the other three.
Sources: Open ASR Leaderboard, English short-form. * Scott, Liang, Wassink and Levow, University of Washington (arXiv:2510.22495).
This measures the speech engine, not the whole app. Rambleproof's own end-to-end time is 1.32s median over 37 dictations (key release to cleaned text at the cursor, MacBook Air M4, macOS 26.5.1). The leaderboard average is over 8 datasets: AMI, Earnings22, GigaSpeech, LibriSpeech clean, LibriSpeech other, SPGISpeech, TED-LIUM v3, VoxPopuli.
| Tool | What was measured | Accuracy | Measured by |

| Rambleproof | Parakeet TDT 0.6B v2 | 6.05% | Open ASR Leaderboard, English short-form |
| Rambleproof | Parakeet TDT 0.6B v3 | 6.32% | Open ASR Leaderboard, English short-form |
| Superwhisper | Whisper large-v3 | 7.44% | Open ASR Leaderboard, English short-form |

Which one fits
Take MacWhisper if files are involved at all. Nothing in Rambleproof will transcribe an interview recording, add subtitles to a video, or watch a folder, and MacWhisper does all three well for one payment.
Take Rambleproof if you never have a file and the job is simply to stop typing. It is free for that indefinitely, it checks the cleaned text before inserting it, and it will not paste into a password field.
Take both if you do both jobs. They do not conflict: one is a file app you open, the other is a shortcut you hold. If you want the wider field first, the best dictation app for Mac guide covers six options, and what dictation apps really cost does the one-year and three-year arithmetic.

Where Rambleproof fits
Unlimited raw local dictation forever, with 20,000 AI-cleaned words each week and deterministic cleanup after that. No app account is required, and every safety feature stays available on Free.
