Whisperstream vs OpenWhispr
Local. One-time. Windows.
Whisperstream is a $29 once, on-your-PC dictation app for Windows. OpenWhispr is an MIT-licensed cross-platform desktop app that ships the same on-device speech model and offers cloud transcription as an option. If you want a single-purpose Windows tool you pay for once and that has no cloud option to flip on, Whisperstream fits. If you want source code, Mac and Linux support, or a multi-feature AI assistant, OpenWhispr is the better answer.

At a glance
Whisperstream is a $29 once, on-your-PC dictation app for Windows. OpenWhispr is an open-source desktop app for Mac, Windows, and Linux that ships the same on-device speech model and adds cloud transcription, AI Notepad, meeting recordings, and an agent mode on top. If you want a focused Windows tool you pay for once and that has no cloud option at all, Whisperstream is the closer fit. If you want source code, cross-platform reach, or the broader AI-assistant surface, OpenWhispr stays the better answer.

Side by side
Pricing
Whisperstream costs $29 once. OpenWhispr has a free tier that covers unlimited local transcription using the same on-device model; the paid Pro tier is $6.67 per user per month billed yearly ($80 a year), or $8 a month if billed monthly. Pro mainly adds managed cloud transcription, 20 hours a month of meeting recording (Free is 5 hours), and an iOS app that OpenWhispr advertises as Coming Soon. Unlimited meeting recording and Agent mode are on Business, not Pro. If your use case is pure local Windows dictation and you can live with OpenWhispr's broader AI-assistant UI, their free tier is the cheapest path. If you want a focused dictation app you pay for once and own forever, Whisperstream is $29 and stops charging after install.
Local-first, by different definitions
Whisperstream transcribes on your PC. Audio never leaves your machine, and there is no cloud transcription option to flip on. The feature does not exist in the product. OpenWhispr defaults to local transcription too, but it offers two cloud options on top: bring your own API key to OpenAI Whisper, Deepgram, AssemblyAI, Groq, or Mistral; or use OpenWhispr Cloud, their managed service (capped at 2,000 words a week on Free, unlimited on Pro). Three transcription modes total. Both products keep on-device data on-device when you choose the local mode. Whisperstream is local-period; OpenWhispr is local-by-default with cloud as a first-class option.
For optional LLM cleanup of transcripts (correcting punctuation, applying a style guide, that kind of thing), Whisperstream lets you choose: on-device LLMs through a local Ollama install you set up yourself, or opt-in cloud LLMs (OpenAI, Anthropic, Gemini). OpenWhispr's AI features (Chat over your data and Agent mode, both on Business) appear to route through cloud LLMs by design. If you want every step of the pipeline to have a local-only configuration, Whisperstream has one. If you are comfortable using cloud LLMs for AI features, OpenWhispr's broader surface gives you more to do with them.
Different shape, not better or worse
Whisperstream does one thing: push-to-talk dictation that types into whatever window has focus. That is the whole product surface. OpenWhispr is broader. The same install ships dictation, an AI Notepad, an AI Chat product, audio file upload for batch transcription, meeting recording, and (on Business) Agent mode and Chat over your data. If you want a single-purpose tool that does dictation cleanly and gets out of the way, Whisperstream is the narrower bet. If you want a Swiss-army-knife voice and text utility on your desktop, OpenWhispr is the broader bet.
When OpenWhispr might still be right
There are four real cases where OpenWhispr is the right answer, not Whisperstream.
- You want the source code. OpenWhispr is MIT-licensed; the full desktop app is open source. You can read it, fork it, and modify it. Whisperstream is closed-source commercial software.
- You use a Mac or Linux. OpenWhispr ships native installers for macOS (Intel and Apple Silicon) and Linux (Debian, Red Hat, AppImage). Whisperstream is Windows-only and not on the roadmap for Mac or Linux.
- You want one app for dictation plus AI Notepad, AI Chat, Audio Upload, meeting recording, and (on Business) Agent mode. OpenWhispr ships those as named features; Whisperstream is dictate-then-paste only, on purpose.
- You want a free tier with a managed cloud option. OpenWhispr Free covers unlimited local transcription and 2,000 words a week of OpenWhispr Cloud, or unlimited cloud transcription if you bring your own OpenAI, Deepgram, AssemblyAI, Groq, or Mistral key. Whisperstream has a 10-minute first-install trial that unlocks via paid purchase, no permanent free tier.

If none of those apply, here is how most OpenWhispr users move over.
Switching from OpenWhispr to Whisperstream
- 01
Decide if you actually want to switch
OpenWhispr Free covers pure local dictation forever at no cost. If that is your use case, switching to Whisperstream may not be worth $29, though some users prefer a dedicated Windows app and a 30-day money-back guarantee. If you are on OpenWhispr Pro paying for managed cloud transcription, the larger meeting-recording allowance, sync across devices, or the iOS app, only switch if you have decided you do not need them.
- 02
Cancel your OpenWhispr Pro subscription (if applicable)
If you are on Pro, open OpenWhispr's account settings and cancel. Your subscription remains active until the billing cycle ends, so you can keep using it while you settle in with Whisperstream. If you are on Free, skip this step.
- 03
Export your custom dictionary
OpenWhispr's Dictionary tab holds the vocabulary you have taught the app. Copy those entries out before you uninstall, if you want them. Whisperstream's word-overrides setting accepts the same one-for-one replacements.
- 04
Install Whisperstream
Download the installer from this page and run it. The first launch downloads the speech model, about 600 MB, which usually takes a few minutes. After that, everything runs offline.
- 05
Set your hotkey, paste your dictionary, and test it in your real apps
Open Whisperstream's settings and pick a push-to-talk hotkey; the default is Right Shift. Paste your exported OpenWhispr vocabulary into the dictionary tab. Then open the apps you usually dictate into, like Outlook, Word, or your editor, and try a sentence in each. If a word lands wrong, add an override and try again. Most users settle the dictionary in one sitting.
