Is there a free trial?

Yes. Download Whisperstream and try it free, no account and no credit card.

Do I need an internet connection?

Only to set up. You'll need internet to download the speech model and to activate your license once. After that, Whisperstream runs offline.

What are the system requirements?

Windows 10 or 11 (64-bit). 8 GB RAM minimum, 16 GB recommended. Works on CPU, no GPU required. A modern processor (Intel 8th gen+ / AMD Ryzen 3000+) gives near-instant transcription.

Can I use one license on more than one PC?

Yes. One purchase activates Whisperstream on up to 2 of your own PCs, like a laptop and a desktop.

What languages do you support?

We support 39 languages: English, Spanish, French, German, Italian, Portuguese, Russian, Polish. As well as: Arabic, Bulgarian, Cantonese, Chinese, Croatian, Czech, Danish, Dutch, Estonian, Filipino, Finnish, Greek, Hindi, Hungarian, Indonesian, Japanese, Korean, Latvian, Lithuanian, Macedonian, Malay, Maltese, Persian, Romanian, Slovak, Slovenian, Swedish, Thai, Turkish, Ukrainian, Vietnamese.

What if it doesn't work for me?

30-day refund, no questions asked. Email support@whisperstream.io.

How does Whisperstream compare to other dictation apps?

We keep honest, side-by-side breakdowns on price, privacy, and how each tool actually runs on Windows. See our comparisons (Wispr Flow, Aqua Voice, OpenWhispr, Win+H) and alternatives roundups (Dragon, MacWhisper, superwhisper) to find where Whisperstream fits.

You think faster than you type.

Typing caps you at 40 to 60 words a minute. You think and speak at roughly three times that. Whisperstream closes the gap without sending a syllable to the cloud.

The privacy guarantee

We physically cannot access your audio.

Here's exactly what happens when you dictate:

1Your microphone captures audio.
2The local NVIDIA model converts it to text.
3The text is typed into your active window.
4The audio is discarded from RAM. Nothing is saved. Nothing is sent.

Transcription makes zero network calls. The only connections Whisperstream opens are license checks and app updates, and none carry your voice or your words. The one exception is opt-in: AI cleanup's free cloud fallback for older PCs.

Local isn't a policy. It's how the transcription works. Nothing to leak. Nothing to log. No data to sell.

Local isn't a policy we wrote. It's how the transcription works. There's no cloud transcription API, no audio upload, and no account tied to your voice. Nothing to leak. Nothing to log. No data to sell.
