Rota AI & OpenAI Whisper: The Complete Dictation Apps Guide
OpenAI Whisper Dictation Apps: The Complete List
TL;DR: There are at least a dozen apps built on OpenAI Whisper for voice dictation and transcription. Some are free, some are paid, some run locally, some use the cloud. I have tested most of them on my Windows machine. Here is the full list with honest comparisons so you can pick the right one.
Let me be real. When OpenAI open sourced Whisper in 2022, it changed everything. Suddenly anyone could build a transcription app with state of the art accuracy. No proprietary APIs. No licensing fees. Just download the model and go.
Fast forward to 2026 and there are Whisper based apps everywhere. Some are dictation tools. Some are transcription tools. Some do both. The problem is figuring out which one actually fits your workflow.
I have been through this. I tested a bunch of these before I built Rota AI. Some were great. Some were abandonware. Some were overpriced for what they did. Let me save you the trouble.
What Makes a Good Whisper Dictation App
Before the list, here is what I think matters:
Accuracy. Obviously. If the transcription is garbage, nothing else matters. Whisper itself is accurate, but the app around it matters too. Does it handle punctuation? Does it clean up filler words? Does it learn your voice?
Workflow. Can you talk and have text appear directly in your target app? Or do you transcribe first and copy paste later? The difference between these two workflows is massive and most reviews do not make this clear.
Privacy. Does your audio go to the cloud or stay on your machine? For some people this is a dealbreaker. For others it does not matter at all.
Price. Free is great. But some paid apps are worth it if they save you time. I will be honest about which ones justify their cost.
Platform. Most Whisper apps are Mac first. Windows support is hit or miss. I will note this for each one.
The Complete List
1. Rota AI
Price: Free (open source, MIT license) Platform: Windows Runs locally: Yes (with Ollama) Best for: Real time dictation into any Windows app
This is the one I built so obviously I am biased. But let me explain why I built it.
I wanted a free dictation tool on Windows that used Whisper for transcription, cleaned up my speech with AI, and dropped text directly into whatever app I was using. Nothing I tried did all three well enough. So I made Rota AI.
What it does:
- Real time dictation with a hotkey (hold to talk, release to transcribe)
- AI cleanup that removes filler words, fixes punctuation, and formats text
- Context awareness (detects VS Code, Slack, browsers, etc. and adjusts behavior)
- Voice snippets for frequently used text
- Works offline with Ollama
- Supports Groq, Gemini, or local Whisper as transcription backends
The trade off: Windows only. Not as polished as some paid options. But free and private.
2. MacWhisper
Price: Free (basic), one time purchase for Pro features Platform: Mac only Runs locally: Yes Best for: Transcribing audio files on Mac
MacWhisper is probably the most popular Whisper frontend on Mac. It is made by Jordy Bruinsma and it is genuinely excellent.
You drag an audio or video file into the app, pick a model size, and it transcribes. That is the core workflow. It supports all the standard Whisper models from tiny to large. The Pro version adds features like batch transcription, speaker detection, and export to more formats.
I used MacWhisper before I found Wispr Flow and it is ridiculously accurate. The large model on a Mac Studio is almost scary how good it is.
The catch: it is a transcription tool, not a dictation tool. You do not hold a hotkey and talk. You record or import audio, transcribe it, then copy the text where you want it. Different workflow. If you need real time dictation, MacWhisper is not that.
Also: Mac only. No Windows version exists and probably never will.
3. Whisper Desktop
Price: Free (open source) Platform: Windows, Mac, Linux Runs locally: Yes Best for: Simple transcription across platforms
Whisper Desktop is an open source GUI wrapper for Whisper. It gives you a simple interface to transcribe audio files without touching the command line.
Think of it as the cross platform version of MacWhisper. You load an audio file, pick a model, hit transcribe, get text. It supports multiple output formats including SRT subtitles.
It is not a dictation tool. It does not do real time transcription. It is for when you already have a recording and need a transcript. But it works on all three major platforms which is rare for Whisper apps.
The interface is basic. It looks like someone built it in an afternoon. But it works and it is free. Sometimes that is all you need.
4. Buzz
Price: Free (open source) Platform: Windows, Mac, Linux Runs locally: Yes Best for: Real time dictation and transcription across platforms
Buzz is the closest thing to a cross platform Rota AI. It does both real time dictation and file transcription. It runs Whisper locally. It is open source.
You can hold a hotkey and speak, and Buzz will transcribe in real time. You can also import audio files for batch transcription. It supports multiple languages and lets you pick your Whisper model size.
I tested Buzz on Windows and it works. The accuracy is solid because it is just Whisper under the hood. The interface is cleaner than Whisper Desktop but not as feature rich as Rota AI. It does not have AI cleanup or context awareness. What you get is raw transcription.
For a free cross platform option that does real time dictation, Buzz is probably your best bet if you are not on Windows or if you need Linux support.
5. SuperWhisper
Price: Free tier available, Pro at $8.49/month Platform: Mac only Runs locally: Yes Best for: Mac users who want a polished dictation experience
SuperWhisper is a Mac only dictation app that uses Whisper locally. It has a clean interface, supports multiple languages, and offers both real time dictation and file transcription.
The free tier is limited. The Pro tier unlocks unlimited transcription, custom vocabulary, and some other features. At $8.49/month it is cheaper than Wispr Flow but still a subscription.
I have not used SuperWhisper as extensively as some others on this list because I am primarily on Windows. But the Mac users I know who use it seem to like it. It is a solid middle ground between the free open source options and the premium paid ones.
6. Wispr Flow
Price: Free tier (5 min/session), Pro at $9.99/month or $79.99/year Platform: Mac, iOS (Windows not yet available) Runs locally: No (cloud based) Best for: Mac users who want the most polished dictation experience
I already wrote a full post on Wispr Flow pricing so I will keep this short. It is the best dictation app on Mac, full stop. The AI cleanup is excellent. The app awareness is best in class. The vocabulary learning is genuinely useful.
But it is Mac only. It is cloud based so your audio goes to their servers. And it costs $10/month for the Pro tier. If you are on Mac and you dictate daily, it is worth the money. If you are on Windows, you are out of luck for now.
7. Whispering
Price: Free (open source) Platform: Mac only Runs locally: No (uses OpenAI API or Groq) Best for: Mac users who want a simple real time dictation app
Whispering is an open source Mac app that does real time dictation using the OpenAI Whisper API or Groq. It is simple, clean, and gets the job done.
The main difference from SuperWhisper is that Whispering uses cloud APIs by default instead of running locally. This means you need internet and you are sending audio to a third party. But the transcription is fast and accurate because it uses OpenAI's servers.
If you do not mind the cloud dependency and you are on Mac, Whispering is a solid free option. It is not as feature rich as Wispr Flow but it costs nothing.
8. aDict
Price: Free Platform: Windows Runs locally: Yes (uses Whisper via faster-whisper) Best for: Windows users who want a simple local dictation tool
aDict is a lightweight Windows dictation app that uses faster-whisper under the hood. It runs locally, it is free, and it does basic real time dictation.
It is not as polished as Rota AI. It does not have AI cleanup or context awareness. But if you just want to hold a hotkey and have Whisper transcribe your speech into any text field, aDict does that.
I found aDict while researching for this post. It is not widely known but it works. your mileage may vary depending on your setup.
9. Voice Typing in Google Docs
Price: Free Platform: Any browser (Chrome works best) Runs locally: No (cloud based) Best for: People who write exclusively in Google Docs
Not a Whisper app technically. Google Docs uses Google's own speech recognition. But I am including it because a lot of people use it and it is worth comparing.
It is free. It works in any browser. Accuracy is decent with good internet. But it only works inside Google Docs, it requires internet, and it does not learn your vocabulary between sessions.
If you write everything in Google Docs already, this is zero friction. If you need dictation in other apps, look elsewhere.
10. Otter.ai
Price: Free tier (300 min/month), Pro at $16.99/month Platform: Web, iOS, Android Runs locally: No (cloud based) Best for: Meeting transcription, not dictation
Otter.ai is not really a dictation app. It is a meeting transcription tool. You record a conversation and Otter transcribes it with speaker identification.
I am including it because people searching for "Whisper dictation apps" sometimes end up considering Otter. It is a good product for what it does. But it is not a replacement for a dictation tool. The workflow is completely different.
If you need meeting notes, Otter's free tier (300 min/month) is generous. If you need to dictate emails or write code by voice, Otter is not the right tool.

Which One Should You Pick
On Windows, want free, want real time dictation: Rota AI or aDict. Rota AI has more features. aDict is simpler.
On Windows, want free, need file transcription: Whisper Desktop or Buzz.
On Mac, want free, want dictation: SuperWhisper free tier or Whispering.
On Mac, want the best experience and will pay: Wispr Flow. It is the best dictation app on Mac, period.
On Mac, need file transcription: MacWhisper. It is the gold standard for local transcription on Mac.
On Linux: Buzz is your best option. Whisper Desktop works too but the interface is rough.
Need meeting transcription: Otter.ai. Different tool for a different job.
Want everything local and private: Rota AI (Windows), MacWhisper (Mac), Buzz (any platform). All run Whisper locally. No cloud. No audio leaving your machine.
My Personal Setup
I use two tools depending on the task.
For real time dictation (writing emails, Slack messages, blog posts, code comments): Rota AI. I built it so it fits my workflow perfectly. I hold my hotkey, talk, and clean text appears in whatever app I am using. The context awareness means it knows when I am in VS Code vs Slack vs a browser.
For transcribing recorded audio (lectures, meeting recordings): faster-whisper via command line. I wrote a whole post about this. It is not as convenient as a GUI but it gives me full control over the model, output format, and processing.
I tried Wispr Flow on a friend's Mac and it is genuinely impressive. If I switched to Mac full time, I would probably pay for it. But on Windows, Rota AI covers my needs.
FAQ
Are all these apps actually using Whisper? Most of them yes. Some like Google Docs Voice Typing and Otter.ai use their own speech recognition models. I noted which ones use Whisper and which do not in the list above.
Which Whisper dictation app is the most accurate? Accuracy depends more on the Whisper model size than the app itself. Most apps let you pick between tiny, base, small, medium, and large. Large is the most accurate but needs a good GPU. Medium is the sweet spot for most people. Wispr Flow and Rota AI with AI cleanup tend to produce the cleanest output because they post process the raw transcription.
Can I use Whisper dictation apps offline? Yes, if the app runs Whisper locally. Rota AI (with Ollama), MacWhisper, Whisper Desktop, Buzz, SuperWhisper, and aDict all run locally. Wispr Flow, Whispering, Google Docs, and Otter.ai require internet because they use cloud APIs.
Is Whisper really free to use? The Whisper model itself is open source and free. You can download it and run it on your machine at no cost. Some apps that use Whisper charge for their software or for cloud API access. But the model weights are free to download from HuggingFace.
What is the best free Whisper dictation app for Windows? Rota AI if you want features. aDict if you want simplicity. Whisper Desktop if you only need file transcription. All three are free and open source.
What about mobile dictation with Whisper? This post focuses on desktop apps. For mobile, your options are more limited. Wispr Flow has an iOS app. Otter.ai has mobile apps. There are some Android apps that use Whisper locally but they tend to be slower because phones have less compute power than desktops. This is an area that will improve as phones get more powerful.
Do any of these work with VS Code or Cursor? Rota AI has specific support for VS Code and Cursor. It detects when you are in a code editor and adjusts its behavior to preserve formatting, camelCase, and snake_case. Buzz and aDict will transcribe into VS Code but they do not have code specific behavior. Wispr Flow has some code awareness on Mac.
How much does it cost to run Whisper locally? Free for the software. The "cost" is hardware. You need enough RAM (8GB minimum, 16GB recommended) and ideally a GPU for faster transcription. The large model needs about 10GB of VRAM. The medium model runs on CPU in a few minutes for a 30 minute audio file. If you have a modern computer, you can run Whisper locally without buying anything.
