SuperWhisper vs Rota AI: Free & Open Source Voice Dictation
SuperWhisper Alternatives That Are Free and Open Source
TL;DR: SuperWhisper costs $8.49/month. That is $101.88/year. If you want the same core functionality (Whisper-powered transcription with AI cleanup) without paying a subscription, there are free and open source alternatives. Rota AI, MacWhisper, Whisper Desktop, and Buzz all do parts of what SuperWhisper does. None of them are a perfect 1:1 replacement. But depending on your platform and workflow, you might not need SuperWhisper at all. Full breakdown below.
I get this question a lot. "Is there a free alternative to SuperWhisper?"
The honest answer: kind of. There is no single free tool that does everything SuperWhisper does. But there are free and open source tools that cover the core use case. Transcribe your voice with Whisper. Clean it up. Get usable text.
Let me walk through the options.
Why People Want a SuperWhisper Alternative
SuperWhisper is a solid product. It got popular for a reason. Andrej Karpathy endorsed it. The feature set is impressive. Screen reading, multiple AI modes, custom prompts. It works on Mac, Windows, and iOS.
But $8.49/month adds up. That is over $100 per year for a dictation tool. For students, for people in countries where that is real money, for anyone watching their budget, that is not nothing.
And some people just prefer open source. They want to see the code. They want to know what happens with their data. They want to build on it or fork it or just audit it.
I fall into all three categories. That is why I built Rota AI. But Rota AI is not the only option. Let me cover the others.
Rota AI
Free. MIT license. Windows only. Built by me.
I am obviously biased. But I will try to be fair.
What Rota AI does:
- Hold a hotkey, speak, get clean text in any app
- AI transcription via Groq (Whisper Large v3), Gemini, or local Ollama
- AI cleanup that removes filler words, resolves self-corrections, formats speech
- Context awareness (detects which app you are in and adjusts tone)
- Offline mode with Ollama (no internet, no API keys, no cloud)
- Voice snippets for frequently used text
- Personal dictionary that learns your vocabulary
- Zero telemetry, local storage, fully private
What Rota AI does NOT do:
- Screen reading (SuperWhisper can read your screen for context)
- Multiple AI output modes (Message mode, Email mode, Super mode)
- Cross-device sync
- Mac or iOS support
Rota AI is the closest thing to a SuperWhisper alternative on Windows. It does the core dictation workflow well. It just does not have the extra layers of polish.
If you are on Windows and you want free, this is the one I built for you. Download it here.
MacWhisper
Free (with a paid Pro tier). Mac only. Open source.
MacWhisper is a native macOS app that wraps OpenAI's Whisper in a clean GUI. It is made by Jordi Bruin and it is genuinely well-designed.
What it does:
- Transcribe audio and video files
- Real-time microphone transcription
- Multiple model sizes (tiny to large)
- Export to TXT, SRT, VTT
- Apple Silicon optimized (runs fast on M-series chips)
- Offline capable (everything runs locally)
The free tier is quite capable. The Pro tier unlocks additional features like custom prompts and batch processing, but the free version handles basic transcription well.
The catch: MacWhisper is primarily a transcription tool, not a dictation tool. It transcribes audio files or live microphone input into its own window. It does not inject text into other apps like SuperWhisper or Rota AI do. You transcribe, then copy-paste.
For people who need to transcribe recordings, interviews, or meetings, MacWhisper is excellent. For people who want to dictate directly into VS Code or Slack, it is not the right workflow.
Best for: Mac users who need file transcription, not live dictation.
Whisper Desktop
Free. Open source. Windows.
Whisper Desktop is a simple GUI wrapper for OpenAI's Whisper model on Windows. It gives you a clean interface for transcription without needing to use the command line.
What it does:
- Transcribe audio and video files
- Multiple Whisper model options
- Simple drag-and-drop interface
- Export transcripts
- Runs locally on your machine
What it does NOT do:
- Real-time dictation into other apps
- AI cleanup or text formatting
- Context awareness
- Voice snippets or hotkey triggers
Whisper Desktop is the most barebones option on this list. It is a transcription tool, period. You drop in a file, it gives you text. No frills.
But sometimes that is all you need. If you have recordings to transcribe and you do not want to pay for a subscription or deal with command line tools, Whisper Desktop works.
Best for: Windows users who need simple file transcription with no setup hassle.
Buzz
Free. Open source. Mac, Windows, Linux.
Buzz is the most feature-rich free alternative on this list. It has been around for a while, has 19.4k stars on GitHub, and supports all three major desktop platforms.
What it does:
- Transcribe audio and video files
- Import from YouTube links
- Live real-time microphone transcription
- Speech separation (demucs) for noisy audio
- Speaker identification
- Multiple Whisper backend support (CUDA, Apple Silicon, Vulkan)
- Export to TXT, SRT, VTT
- Advanced transcription viewer with search and playback
- Watch folder for automatic transcription
- Command-line interface for scripting
Buzz is genuinely impressive for a free tool. The live transcription feature works well. The speaker identification is useful for meetings. The cross-platform support means it does not matter what OS you are on.
The catch: like MacWhisper and Whisper Desktop, Buzz is primarily a transcription tool. The live transcription opens in its own window. It does not inject text into other apps in real time the way SuperWhisper or Rota AI do. You still copy-paste.
Also, the Windows version is not signed, so you will get a security warning during installation. You have to click "More info" and "Run anyway." Not ideal, but it is the reality of open source Windows apps without a code signing certificate.
Best for: Anyone on any platform who needs a full-featured transcription tool with live capture.

| Speaker identification | No | No | No | No | Yes |
| YouTube import | No | No | No | No | Yes |
The table makes it clear. SuperWhisper is the most complete product. It does real-time dictation into apps AND has screen reading AND multiple AI modes. Nothing else on this list matches that feature set.
But if your main need is file transcription, Buzz and MacWhisper are excellent. If you need real-time dictation into apps on Windows, Rota AI is your best free bet.
What I Actually Use
I use Rota AI. Obviously. I built it for my own workflow and it covers what I need.
But I have also used Buzz for transcribing longer audio files. When I record a lecture or a meeting, I drop it into Buzz and let it run. The speaker identification is handy. The export options are flexible.
I have not used MacWhisper personally because I am on Windows. But I have heard good things from Mac users. If I switched to Mac, it would be one of the first things I install.
Whisper Desktop I tried once. It works fine for what it is. I just needed more than it offers.
SuperWhisper I have used during a trial. It is good. The screen reading feature is genuinely useful. The multiple AI modes are well-implemented. If I were on Mac and had the budget, I would probably pay for it.
But I am not on Mac. And I do not have the budget. So here we are.

FAQ
Is there a completely free alternative to SuperWhisper?

Does Rota AI work on Mac?
Not yet. Windows only. For Mac, try MacWhisper for transcription or SuperWhisper for full dictation.
Is Buzz safe to install on Windows?
Yes. It is open source and the code is auditable. The Windows installer is not code-signed, so you will get a security warning. This is common for open source projects that cannot afford signing certificates. The app itself is safe.

Can I use these tools for coding by voice?
Rota AI works in VS Code and Cursor. It detects the app and preserves code formatting. Buzz and MacWhisper can transcribe what you say, but you will need to copy-paste into your editor. SuperWhisper works in any app on Mac.
What about Wispr Flow?
Wispr Flow is the other paid option at $15/month. I wrote about it in my Is Wispr Flow Worth It post. It is more polished than SuperWhisper but also more expensive. If you are comparing all three, the price ladder is: free (Rota AI/Buzz) < $8.49/mo (SuperWhisper) < $15/mo (Wispr Flow).
I am a student on a tight budget. What should I pick?
If you are on Windows: Rota AI. If you are on Mac: MacWhisper for transcription, or save up for SuperWhisper if you need live dictation. If you need cross-platform: Buzz. All free. All open source. All better than paying $101.88/year when you do not have to.
