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?

This thread is a support group for people who have each independently built the same macOS speech-to-text app.

Nice one! For Linux folks, I developed https://github.com/goodroot/hyprwhspr.

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. :)

Speech-to-text has become integral part of my dev flow especially for dictating detailed prompts to LLMs and coding agents.

I have collected the best open-source voice typing tools categorized by platform in this awesome-style GitHub repo. Hope you all find this useful!

https://handy.computer/ already exists?

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?

I see a lot of whisper stuff out there. Are these the same old OpenAI whispers or have they been updated heavily?

I've been using parakeet v3 which is fantastic (and tiny). Confused why we're still seeing whisper out there, there's been a lot of development.

[−] konaraddi 39d ago
That’s awesome! Do you know how it compares to Handy? Handy is open source and local only too. It’s been around a while and what I’ve been using.

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.

Parakeet is significantly more accurate and faster than Whisper if it supports your language.

Speecg-to-text is basically AI version of Todo app that we used to build every week when new frontend framework would release.
[−] __mharrison__ 39d ago
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.

You can get a lot done with two buttons.

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.

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).

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.
[−] marktolson 38d ago
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".

Other than that issue I like it.

[−] raybb 39d ago
Would also like to know how it compares to https://github.com/openwhispr/openwhispr

I like that openwhisper lets me do on device and set a remote provider.

[−] mft_ 37d ago
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.)

[−] snickell 39d ago
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?

[−] acjacobson 38d ago
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.

[−] hyperhello 39d ago
Feature request or beg: let me play a speech video and transcribe it for me.
[−] rcarmo 39d ago
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?
[−] nidnogg 38d ago
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.

[−] ghm2199 39d ago
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.

[−] boudra 39d ago
Interesting, I'm surprised you went with Whisper, I found Parakeet (v2) to be a lot more accurate and faster, but maybe it's just my accent.

I implemented fully local hands free coding with Parakeet and Kokoro: https://github.com/getpaseo/paseo

[−] jwr 38d ago
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.

[−] miki123211 38d ago
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.

[−] ianmurrays 38d ago
I had Claude make this hammerspoon config + daemon that does pretty much the same, in case anyone is interested.

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.
[−] maxmorrish 39d ago
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
[−] aristech 39d ago
Great job. How about the supported languages? System languages gets recognised?
[−] janalsncm 39d ago
I think the jab at the bottom of the readme is referring to whispr flow?

[−] pdyc 39d ago
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
[−] Supercompressor 39d ago
I've been looking for the opposite - wanting to dump text and it be read to me, coherently. Anyone have good recommendations?
[−] tito 39d ago
This is great. I'm typing this message now using Ghost Pepper. What benefits have you seen from the OCR screen sharing step?
[−] guzik 39d ago
Sadly the app doesn't work. There is no popup asking for microphone permission.

EDIT: I see there is an open issue for that on github

[−] kingofbits 36d ago
Nicely done! Ive been abusing chatgpt's overlay window for this, until now
[−] pmarreck 39d ago
How does this compare with Superwhisper, which is otherwise excellent but not cheap?
[−] jannniii 38d ago
Oh dear, why does it not use apfel for cleanup? No model download necessary…
[−] gegtik 39d ago
how does this compare to macos built in siri TTS, in quality and in privacy?
[−] purplehat_ 39d ago
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?

[−] therealdeal2020 38d ago
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
[−] imazio 39d ago
is this the support group for people building speech-to-text apps?

I built https://yakki.ai

No regrets so far! XP

[−] leeeeep101 36d ago
i also did this dictatorflow lee101/voicetype i open sourced it also. nice. might be good reference :)
[−] vaulpann 39d ago
very cool - huge open source drop!
[−] thatxliner 39d ago
why isn't the cleanup done on the transcription (as opposed to screen record)
[−] dakila5 39d ago
MacWhisper is also a good one
[−] douglaswlance 39d ago
does it input the text as soon as it hears it? or does it wait until the end?
