Local. One-time. Windows.
Whisperstream is a $29-once, on-your-PC dictation app for Windows. Willow Voice is a $12-per-month cloud app for Mac, Windows, and iPhone that pairs transcription with AI rewriting.

Side by side
Pricing
Whisperstream costs $29 once. Willow Voice's Individual tier is $12 a month billed annually, which works out to $144 a year. Over three years, that adds up to $432, all of which stays in your wallet with Whisperstream. Both apps run on Windows; only one of them stops charging after install.
Privacy
Whisperstream transcribes on your PC. Audio never leaves your machine. Willow Voice uploads audio to its servers for processing, and by default reads on-screen text from the active window to sharpen results. Both behaviors are documented in Willow's privacy policy. If you want zero cloud upload, Whisperstream is the simpler answer; if you want cloud-side context, Willow Voice is built around it.
Willow Voice's own privacy policy confirms both behaviors: audio is processed on Willow's cloud servers, and the “Context Awareness” feature reads relevant text from the active window to improve transcription. Willow's opt-in Private Mode reduces what is stored on Willow's side but does not move transcription to your device.
AI rewriting
Willow Voice runs your transcript through an AI cleanup pass. The homepage describes it as “fixes grammar, punctuation, and formatting as you speak,” and the company's AI Mode turns a few quick words into a polished message. The text-to-text rewriting pipeline uses Meta Llama models.
Whisperstream does not do that. The text it pastes is what you said, normalized for punctuation and (optionally) replaced through your word-override dictionary and a small style guide. The choice is deliberate. Some workflows want raw transcription that does not second-guess what was dictated; legal testimony, code, technical notes, and anything where editorial drift is the bigger risk. Other workflows want AI-shaped prose. Willow ships the rewriting layer; Whisperstream skips it on purpose.
When Willow Voice might still be right
There are four real cases where Willow Voice is the right answer, not Whisperstream.
- You use a Mac or an iPhone. Whisperstream is Windows-only; Willow Voice ships native Mac and iOS apps and a voice-keyboard on iOS.
- You want AI rewriting that polishes rough speech into finished text. Willow's AI Mode and grammar fixes turn dictation into edited prose; Whisperstream gives you raw transcription with a style guide and word-overrides, which is what some teams want and what others don't.
- You need Enterprise-tier SOC 2 or HIPAA compliance with shared team dictionaries. Willow's Enterprise tier ships that paperwork; Whisperstream is a single-user app today.
- You want a voice-keyboard on iPhone. Willow has an iOS app and keyboard; Whisperstream does not ship a mobile app.

If none of those apply, here is how most Willow Voice users move over in a few minutes.
Switching from Willow Voice to Whisperstream
- 01
Cancel your Willow Voice subscription
Open the Willow billing page and cancel. Your subscription stays active until the current cycle ends, so you can keep dictating with it while you settle in with Whisperstream.
- 02
Export your custom dictionary entries
Willow's Auto-Dictionary and Custom Dictionary settings hold the vocabulary you have taught it. Copy those entries out before you cancel. Whisperstream's word-overrides setting accepts the same one-for-one replacements; you will paste them in during step four.
- 03
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.
- 04
Set your hotkey and dictionary
Open Whisperstream's settings and pick a push-to-talk hotkey; the default is Right Shift. While you are in settings, paste your exported Willow vocabulary into the dictionary tab.
- 05
Test it in your real apps
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.
