THE FOUNDER PRIVACY PROMISE

Your voice belongs to you.
We never hear it, store it, or train on it.

Most modern voice apps require you to funnel all your private thoughts, patient records, or business emails through their proprietary cloud servers. Untether is architected completely differently:

Zero Server Middlemen: Audio travels directly from your PC to Groq via encrypted TLS. Untether has no backend server storing or intercepting your files.
Bring Your Own Key (BYOK): You own the API credentials. You decide which models to use, and you control your data retention policies.
True Air-Gapped Local Option: Need 100% HIPAA or GDPR isolation? Untether includes a built-in offline engine powered by local Whisper.

Questions & Answers

Frequently Asked Questions

How much does Untether cost? Are there recurring subscriptions?

Untether does not charge annoying recurring monthly subscriptions. You download the desktop application and supply your own Groq API key, which has a generous free tier that allows thousands of dictations per month at zero cost.

Do I have to pay for Groq?

No. Groq offers a generous free tier with zero monthly cost and no credit card required to get started. For 95% of users, the free tier limit is more than enough for daily voice dictation.

Can I customize the hotkey?

Yes. The default hotkey is holding Ctrl + Shift. Inside Untether Studio, you can configure your own key combinations, adjust push-to-talk delays, or toggle between hold-to-talk and click-to-toggle modes.

Can I use this for clinical or doctor notes?

Untether includes templates for clinical formatting (SOAP notes). However, Untether is a general-purpose productivity utility and not an FDA/CE certified medical device. Clinical professionals must always review and verify all generated text before signing off.

What are the system requirements?

Windows 10 or Windows 11 (64-bit), an active microphone, and an internet connection for Groq mode. (For offline local Whisper mode, an Nvidia GPU with CUDA is recommended, though standard multi-core CPU is also supported).
