Whisperstream

Private offline dictation for Windows with a one-time price.

Quick answer

Whisperstream — Private offline dictation for Windows with a one-time price. It's free trial. Best for privately dictating notes, emails, or documents on a Windows PC without cloud exposure.

Whisperstream is a one-time-purchase, CPU-only local dictation app for Windows that lets you speak text directly into any application without your audio ever leaving your machine. Designed for privacy-conscious Windows users who are tired of monthly subscription fees, Whisperstream uses a push-to-talk hotkey to capture your voice and instantly paste transcribed text into whatever window you have open. The transcription engine runs entirely on your CPU with no audio-upload path, making it a strong choice for professionals handling sensitive information, developers, writers, and anyone who wants full control over their data. It supports a broad range of applications out of the box, including a documented workflow for dictating into Claude Code, which makes it particularly appealing to developers using AI coding assistants. A one-time license covers up to two PCs, so it pays for itself quickly compared to competing subscription-based dictation tools. Whisperstream requires Windows 10 or 11 with at least 8 GB of RAM, and there is no macOS or Linux version available at this time. A free trial is available with no account required, and a 30-day money-back guarantee removes risk from the purchase decision.
