I built this because I wanted to see how far I could get with a voice-to-text app that used 100% local models so no data left my computer. I've been using a ton for coding and emails. Experimenting with using it as a voice interface for my other agents too. 100% open-source MIT license, would love feedback, PRs, and ideas on where to take it.
This is great, and I'm not knocking it, but every time I see these apps it reminds me of my phone.
My 2021 Google Pixel 6, when offline, can transcribe speech to text, and also corrects things contextually. it can make a mistake, and as I continue to speak, it will go back and correct something earlier in the sentence. What tech does Google have shoved in there that predates Whisper and Qwen by five years? And why do we now need a 1Gb of transformers to do it on a more powerful platform?
It's the same model used for the WebSpeech API, which can operate entirely offline.
Google mostly funded the training of this model around 10 years ago, and it's quite good.
There are many websites that are simple frontends for this model which is built into Webkit and Blink based browsers. However to my knowledge the model is a blob packed into the apps which is not open source, hence the no Firefox support.
Microsoft OneNote had this back in 2007 or so, granted the speech to text model wasn't nearly as advanced as they are now.
I was actually on the OneNote team when they were transitioning to an online only transcription model because there was no one left to maintain the on device legacy system.
It wasn't any sort of planned technical direction, just a lack of anyone wanting to maintain the old system.
I remember trying out some voice-to-text around 2002 that I believe was included with Windows XP.. or maybe Office?
You had to go through some training exercises to tune it to your voice, but then it worked fairly well for transcription or even interacting with applications.
Any particular reason why you switched? I've been using Gboard for years, especially the text to speech in four languages. In the past few weeks, there was an update where the TTS feature is now in a separate "panel" of the keyboard, and it hardly works at all.
In English and Hebrew it stops after half a dozen words, and those words must be spoken slowly and mechanically for it to work at all. Russian and Arabic are right out - I can't coax any coherent sentence out of it.
I've gone through all permutations of relevant settings, such as "Faster Voice Dictation" (translated from Hebrew,I don't know what the original English option is called). I think there used to be an option for Online or Offline transcription, but that option is gone now.
This is ridiculous - I tried to copy the version information and there is no way to copy it in-app. Let's try the S24 OCR feature...

Interesting. My Pixel 7 transcription is barely usable for me. Makes way too many mistakes and defeats the purpose of me not having to type, but maybe that's just my experience.
The latest open source local STT models people are running on devices are significantly more robust (e.g. whisper models, parakeet models, etc.). So background noise, mumbling, and/or just not having a perfect audio environment doesn't trip up the SoTA models as much (all of them still do get tripped up).
I work in voice AI and am using these models (both proprietary and local open source) every day. Night and day different for me.
I've built my own tts apps testing whisper and while it's good it does hallucinate quite a bit if there's noise, or just sometimes when the audio is perfectly clear.
It often gives the illusion of being very good but I could record a half hour of me speaking and discover some very random stuff in the middle that I did not say
Yup, you're absolutely right. The open source models do have their rough edges. I use NVIDIA's Parakeet v3 model a lot locally, and it will occasionally do this thing where it just repeats a word like a dozen times.
When you activate it you agree that your voice input is sent to Apple. As far as I understand this project runs fully locally. Up to you to decide for whatever suits your needs best.
"When you use Dictation, your device will indicate in Keyboard Settings if your audio and transcripts are processed on your device and not sent to Apple servers. Otherwise, the things you dictate are sent to and processed on the server, but will not be stored unless you opt in to Improve Siri and Dictation."
And:
"Dictation processes many voice inputs on your Mac. Information will be sent to Apple in some cases."
In conclusion... I think they're trying to cover all their bases, but it sounds like things are processed locally as long as the hardware can handle it.
No, that is not correct. It is running one hundred percent local. You can try it by turning off internet on your phone and try running it then. However, the built in model isn't as good, so this is probably better.
I just don't have the bandwidth to run another project, maintaining Handy is hard enough on it's own, especially for free!
I didn't just dismiss for no reason, I am a human! I have needs and I can't just sleeplessly stay in front of the computer putting out code. If I had more time I would, but alas.
Someone could easily vibe code an iOS version in a few hours. I could do the same but I do not have time to support it.
It has all the usual features, plus you can add project specific vocabulary in your repo. It detects the working folder based on the active window, reads a WORDBIRD.md file in that folder and corrects terms accordingly.
Awesome, thanks. Now it looks like five features are table stakes and there's no need to filter for, for example, speech to text. So, it would be interesting to see the differentiation, the why would I choose which one.
I see promise trying to get a bit more into curating by showing the top one or two or three picks for a given standout feature.
So... a vibe slop index to keep track of all the vibe slop apps?
The cherry on top: it’s completely broken! Enable the Context Awareness filter, the list shrinks. Now enable the Auto-pasting filter, the list grows back.
I wouldn't call it completely broken; Pressing buttons still does something, it looks like an OR filter instead of an AND. It should be updated to be an AND filter as that's more intuitive.
If you squint, it looks kinda maybe superficially useful? But if you actually critically look at it, it makes no sense.
The categories are clearly LLM generated from the GhostPepper codebase, with vague low level descriptions and links to code. Most categories apply to every listed project.
The UI is the same tiny bit of LLM generated information displayed five different confusing ways. Like seriously, click on a project and you first see a bunch of haphazard feature cards, then a bunch of “feature ... active” rows. Looks fancy, but actually just noise. Textbook slop.
Better would be a simple awesome-style markdown page, with a feature matrix having categories and descriptions curated by a human that actually understands and cares about the domain.
Sorry if this is harsh, but passing off LLM output as “curation” is particularly insulting to me.
In the /r/macapps subreddit, they have huge influx of new apps posts, and the "whisper dictation" is one of the most saturated category. [0]
>“Compare” - This is the most important part. Apps in the most saturated categories (whisper dictation, clipboard managers, wallpaper apps, etc.) must clearly explain their differentiation from existing solutions.
I cobbled my own together one night before I came across the thoughtfully-built KeyVox and got to talking shop with its creator. Our cups runneth over. https://github.com/macmixing/keyvox/
Yeah, but mine... Oh. Hello. sighs It's been three weeks since I tried to add feature to my version of the app. I don't miss it. I like this new life. Sober.
I'll have you know that I'm Matt's top contributor to Ghost Pepper and I'm nearly fifty
But I did it because I wanted it to work exactly the way I wanted it.
Also, for kicks, I (codex) ported it to Linux. But because my Linux laptop isn't as fast, I've had to use a few tricks to make it fast. https://github.com/obra/pepper-x
I recently attended a agentic SWE workshop and the starter project was this, whispr style, local voice dictation app. Took everybody around 30mins. tbh: i was kinda impressed.
Its gotten so bad that its a meme on the macapps subreddit.
This is the unfortunate real face of open source. So many devs each making little sandcastles on their own when if efforts were combined, we could have had something truly solid and sustainable, instead of a litany of 90% there apps each missing something or the other, leaving people ending up using WisprFlow etc.
On Linux, there's access to the latest Cohere Transcribe model and it works very, very well. Requires a GPU though. Larger local models generally shouldn't require a subordinate model for clean up.
Have you compared WhisperKit to faster-whisper or similar? You might be able to run turbov3 successfully and negate the need for cleanup.
Incidentally, waiting for Apple to blow this all up with native STT any day now. :)
How does it compare to the more well established https://github.com/cjpais/handy? Are there any stand out features (for either option)? What was the reason for writing your own rather than using or improving existing software?
I've been running whisper large-v3 on an m2 max through a self-hosted endpoint and honestly the accuracy is good enough that i stopped bothering with cleanup models. The bigger annoyance for me was latency on longer chunks, like anything over 30 seconds starts feeling sluggish even with metal acceleration. Haven't tried whisperkit specifically but curious how it handles longer audio compared to the full model.
Yeah that makes sense, chunking on silence would sidestep the latency issue pretty cleanly. I've been running it through a basic fastapi wrapper so it just takes whatever audio blob gets thrown at it, no chunking logic on the server side. Might be worth adding a vad pass before sending to whisper though, would cut down on processing dead air too.
Maintainer of WhisperKit here, confirming we do exactly that for longform. We search for the longest "low energy" silence in the second half of the audio window and set the chunking point to the middle of that silence. It uses a version of the webrtc vad algorithm, and significantly speeds up longform because we can run a large amount of concurrent inference requests through CoreML's async prediction api. Whisper is also pretty smart with silent portions since the encoder will tell it if there are any words at all in the chunk, and simply stop predicting tokens after the prefill step - although you could save the ~100ms encoder run entirely with a good vad model, which our recently opensourced pyannote CoreML pipeline can do.
Oh nice, the pyannote coreml port is interesting. Last time I looked at pyannote it was pytorch only so getting it to run efficiently on apple silicon was kind of a pain. Does the coreml version handle diarization or just activity detection?
Can you explain how exactly dictation is used for development? I type about 120 WPM so typing is always going to be way faster for me than talking. Aside for accessibility, is dictation development for slower typers or is it more so you can relax on a couch while vibe coding? If this comes off as condescension it's not intended, I am genuinely out of the loop here.
I think most people can speak faster than 120 WPM. For example this site says I speak at 343 WPM https://www.typingmaster.com/speech-speed-test/, and I self-measure 222 WPM on dense technical text.
For me personally, it's not really about typing speed. While I can type pretty fast and most likely I speak faster than typing, but typing and dictating are just different way of doing things for me. While the end result of both is same, but for me it's just like different way of doing things and it's not a competition between the two.
I regularly just sit down and often just describe whatever I'm trying to do in detail and I speak out loud my entire thought process and what kind of trade-offs I'm thinking, all the concerns and any other edge cases and patterns I have in my mind. I just prefer to speak out loud all of those. I regularly speak out loud for 5 to 10 minutes while sometimes taking some breaks in between as well to think through things.
I am not doing it just for vibe coding, I'm using it for everything. So obviously for driving coding agents, but also for in general, describing my thoughts for brainstorming or having some kind of like a critique session with LLMs for my ideas and thoughts. So for everything, I'm just using dictation.
One other benefit I think for me personally is that since I'm interacting with coding agents and in general LLMs a lot again and again every day, I end up giving much more context and details if I'm speaking out loud compared to typing. Sometimes I might feel a little bit lazy to type one or two extra sentences. But while speaking, I don't really have that kind of friction.
1. For a Linux user, you can already build such a system yourself quite trivially by getting an FTP account, mounting it locally with curlftpfs, and then using SVN or CVS on the mounted filesystem. From Windows or Mac, this FTP account could be accessed through built-in software.
2. It doesn't actually replace a USB drive. Most people I know e-mail files to themselves or host them somewhere online to be able to perform presentations, but they still carry a USB drive in case there are connectivity problems. This does not solve the connectivity issue.
3. It does not seem very "viral" or income-generating. I know this is premature at this point, but without charging users for the service, is it reasonable to expect to make money off of this?
Thank you for sharing, I appreciate the emphasis on local speed and privacy. As a current user of Hex (https://github.com/kitlangton/Hex), which has similar goals, what are your thoughts on how they compare?
Whisper is still old reliable - I find that it's less prone to hallucinations than newer models, easier to run (on AMD GPU, via whisper.cpp), and only ~2x slower than parakeet. I even bothered to "port" Parakeet to Nemo-less pytorch to run it on my GPU, and still went back to Whisper after a couple of days.
I'm also wondering whether or not it would be beneficiary for my workload to switch over to Parakeet. Problem is, I'm using a lot of lingo - and in Polish, as well! - so it's not exactly the best case and whisper (v3), so far, works.
Handy is an awesome project, highly recommended - many of our engineers and PMs use it! CJ, Handy's creator, recently joined us as a Builder in Residence at Mozilla.ai. So for those interested in deploying a more raw/lightweight approach to local speech-to-text (or other multimodal) models, feel free to check out llamafile - which includes whisperfile, a single-file whisper.cpp + cosmopolitan framework-based executable. We're hoping to build some bridges between the two projects as well. https://github.com/mozilla-ai/llamafile
I’d also be interested to know what the impetus was for developing ghost-pepper, which looks relatively recent, given that Handy exists and has been pretty well received.
Extra bonus is that Handy lets add an automatic LLM post-processor. This is very handy for the Parakeet V3 model, which can sometimes have issues where it repeats words or makes recognition errors for example, duplicating the recognition of a single word a dozen dozen dozen dozen dozen dozen dozen dozen times.
Yep. Using Handy with Parakeet v3 + a custom coding-tailored prompt to post-process on my 2019 Intel Mac and it's been working great.
Once in a while it will only output a literal space instead of the actual translation, but if I go into the 'history' page the translation is there for me to copy and paste manually. Maybe some pasting bug.
Handy is awesome! I used it for quite a while before Claude Code added voice support. Solid software, very good linux and mac integration. Shoutout to Parakeet models as well, extremely fast and solid models for their relatively modest memory requirements.
I love and have been using handy for a while too, what we need is this for mobile apps I don't think there's any free apps and native dictation is not always fully local and not as good.
I see quite a few of these, the killer feature to me will be one that fine tunes the model based on your own voice.
E.G. if your name is `Donold` (pronounced like Donald) there is not a transcription model in existence that will transcribe your name correctly. That means forget inputting your name or email ever, it will never output it correctly.
Combine that with any subtleties of speech you have, or industry jargon you frequently use and you will have a much more useful tool.
We have a ton of options for "predict the most common word that matches this audio data" but I haven't found any "predict MY most common word" setups.
Cool, I've been doing a lot of "coding" (and other typing tasks) recently by tapping a button on my Stream Deck. It starts recording me until I tap it again. At which point, it transcribes the recording and plops it into the paste buffer.
The button next to it pastes when I press it. If I press it again, it hits the enter command.
This is exactly what I am building right now, Stream Deck with two buttons too (push to talk and enter)! It's a sweet little pet project, and has been a blast to build so far. Excited to finally add it to my workflow once its working well.
This got me thinking that the smaller these local first LLMs get - the more they're gonna looking the next bread and butter of app dev. Reminds me how Electron gained a lot of traction for making it easy to package prettier apps. At the measly cost of gigabytes of RAM, give or take.
The clean up prompt needs adjusting. If your transcription is first person and in the voice of talking to an AI assistant, it really wants to “answer” you, completing ignoring its instructions. I fiddled with the prompt but couldn’t figure out how to make it not want to act like an AI assistant.
If you don't feel like downloading a large model, you can also use `yap dictate`. Yap leverages the built-in models exposed though Speech.framework on macOS 26 (Tahoe).
I got it to transcribe this: "Create tests and ensure all tests pass" and instead of transcribing exactly what I said it outputs nonsense around "I am a large language model and I cannot create and execute tests".
Does it show your spoken words on the screen live (i.e. streaming) or does it wait until you’ve finished speaking?
I find it very helpful to see my words live - for some reason it helps my simple brain structure what I’m saying, and I’m much more fluent as a result.
I went on a mission a few weeks ago and tried every freely available MacOS STT app I could find (and there are lots of them) - but none I tried had this feature and was otherwise satisfactory. (I vibe-coded a PoC which could do this, so it’s definitely possible.)
Can somebody help me understand how they use these, I feel like I'm missing something or I'm bad at something?
I only spent 10 minutes with Handy, and a similar amount of time with SuperWhisper, so pretty ignorant. I tried it both with composing this comment, and in a programming session with Codex. I was slightly frustrated to not be hands free, instead of typing, my hands were having to press and release a talk button (option-space in handy, right-command in superwhisper), but then I couldn't submit, so I still had to click enter with Codex.
Additionally, for composing this message, I'm using the keyboard a ton because there's no way I can find to correct text I've typed. Do other people get really reliable and don't need backspace anymore? Or.... what text do you not care enough to edit? Notes maybe?
My point of comparison is using Dragon like 15 years ago. TBH, while the recognition is better (much better) on handy/superwhisper, everything else felt MUCH worse. With dragon, you are (were?) totally hands free, you see text as you say it, and you could edit text really easily vocally when it made a mistake (which it did a fair bit, admittedly). And you could press enter and pretty functionally navigate w/o a keyboard too.
Its weird to see all these apps, and they all have the same limitations?
Nice app! Feedback since you asked: The most obvious must-have feature IMO is to paste automatically. Don't require me to hit a shortcut (or at least make it configurable)
The next most critical thing I think is speed and in my tests it's just a little bit slower than other solutions. That matters a lot when it comes to these tools.
The third thing, more of a nice to have is controlling formatting. By this I mean - say a few sentences, then "new line" and the model interprets "new line" as formatting, not as literal text.
I like this idea and it should work -- whatever microphone you have on should be able to hear the speaker. LMK if not (e.g., are you wearing headphones? if so, the mic can't hear the speaker)
Not sure why I should use this instead of the baked-in OS dictation features (which I use almost daily--just double-tap the world key, and you're there). What's the advantage?
I haven't used this one but WisprFlow is vastly better than the built-in functionality on MacOS. Apple is way behind even startups, even for fundamental AI functionality like transcribing speech
I'm speaking for >1 minute and including bulleted lists, etc. WisprFlow gets all of the bulleted lists formatted correctly, and I'm not saying things like "Bullet 1" -- just speaking as I'd speak to a person.
I really like the project and am eager to try and fit this into some of my workflows. However, this bothered me a bit:
"All models run locally, no private data leaves your computer. And it's spicy to offer something for free that other apps have raised $80M to build."
I’d straight up drop the comparison to big AI labs. This isn’t rebellious or subversive, it’s downstream of a ton of already-funded work. Calling it “spicy” is a bit misframed.
I've been using handy since a month and its awesome. I mainly use it with coding agents or when I don't want to type into text boxes. How is this different?
Part of the reason handy is awesome is because it uses some of the same rust infra for integrating with the model, so that actually makes it possible to use the code as a library in android or iOS. I have an android app that runs on a local model on the phone too using this.
I currently use MacWhisper and it is quite good, but it's great to see an alternative, especially as I've been looking to use more recent models!
I hope there will be a way to plug in other models: I currently work mostly with Whisper Large. Parakeet is slightly worse for non-English languages. But there are better recent developments.
What do you actually use for STT, particularly if you prize performance over privacy and are comfortable using your own API keys?
I was on WhisperFlow for a while until the trial ran out, and I'm really tempted to subscribe. I don't think I can go back to a local solution after that, the performance difference is insane.
Try ottex.ai - it has an OpenRouter like gateway with most STT models on the market (Gemini, OpenAI, Groq, Deepgram, Mistral, AssemblyAI, Soniox), so you can try them all and choose what works best for you.
My favorites are Gemini 3 Flash and Mistral Voxtral Transcribe 2. Gemini when I need special formatting and clean-up, and Voxtral when I need fast input (mostly when working with AI).
Hi, nice project! Quick question, when I speak Chinese language, why it output English as translated output? I was using the multilingual (small) model. Do I need to use the Parakeet model to have Chinese output? Thx.
love seeing more local-first tools like this. feels like theres been a real shift since the codebeautify breach last year, people are actually thinking about where there data goes now. nice work on keeping it all on device
Thanks! We currently have 2 multi-lingual options available:
- Whisper small (multilingual) (~466 MB, supports many languages)
- Parakeet v3 (25 languages) (~1.4 GB, supports 25 languages via FluidAudio)
interesting, i wanted something like this but i am on linux so i modified whisper example to run on cli. Its quite basic, uses ctrl+alt+s to start/stop, when you stop it copies text to clipboard that's it. Now its my daily driver https://github.com/newbeelearn/whisper.cpp
Exactly my question. I double-tap the control button and macOS does native, local TTS dictation pretty well. (Similar to Keyboard > Enable Dictation setting on iOS.)
The macOS built-in TTS (dictation) seems better than all the 3rd party, local apps I tried in the past that people raved about. I have tried several.
Is this better somehow?
If the 3rd party apps did streaming with typing in place and corrections within a reasonable window when they understand things better given more context, that would be cool. Theoretically, a custom model or UX could be "better" than what comes free built into macOS (more accurate or customizable).
But when I contacted the developer of my favorite one they said that would be pretty hard to implement due to having to go back and make corrections in the active field, etc.
I assume streaming STT in these utilities for Mac will get better at some point, but I haven't seen it yet (been waiting). It seems these tools generally are not streaming, e.g. they want you to finish speaking first before showing you anything. Which doesn't work for me when I'm dictating. I want to see what I've been saying lately, to jog my memory about what I've just said and help guide the next thing I'm about to say. I certainly don't want to split my attention by manually toggling the control (whether PTT or not) periodically to indicate "ok, you can render what I just said now".
I guess "hold-to-talk" tools are for delivering discrete, fully formed messages, not for longer, running dictation.
AFAICT, TFA is focused on hold-to-talk as the differentiator, over double-tap to begin speaking and double-tap to end speaking?
Hi Matt, there's lots of speech-to-text programs out there with varying levels of quality. 100% local is admirable but it's always a tradeoff and users have to decide for themselves what's worth it.
Would you consider making available a video showing someone using the app?
btw I know at least a dozen doctors that still pay for software like this. I think doctors are THE profession that likes to use speech-to-text all day every day
Windows has a native (cloud-based) dictation software built-in[1], so there's likely less demand for it. Nonetheless, there are still a handful of community options available to choose from.
Because like all other modern Macs, the GPU in my Mac uses the same API as the GPU in your Mac.
Also, on a Mac with 32GB of RAM, 24GB of that (75%) is available to the GPU, and that makes the models run much faster. On my 64GB MacBook Pro, 48GB is available to the GPU. Have you priced an nvidia GPU with 48GB of RAM? It’s simply cheaper to do this on Macs.
Macs are just better for getting started with this kind of thing.
