Whisperstream

Local AI dictation for Windows. 100% on-device. $29 one-time

Visit

Whisperstream is a Windows-native dictation app that runs 100% on your PC. Press a push-to-talk hotkey, speak, and your transcribed words paste into whatever window has focus: your IDE, your email, your notes, Slack. Transcription runs locally on the CPU via NVIDIA Parakeet TDT v3 (ONNX Runtime). Audio never touches the network.

Built for Windows vibe coders dictating into Cursor, Claude Code, or VS Code; privacy-critical professionals (legal, healthcare, defense); accessibility and RSI users; writers; and academics. The wedge: Windows-native, fully local, one-time pricing. Differentiation versus cloud-tied dictation tools that charge a subscription or fail compliance requirements.

  • Builders dictating into Cursor, Claude Code, VS Code, and JetBrains IDEs who don't want code-related speech going to a third-party API.
  • Accessibility and RSI users who need a hotkey-and-speak workflow without learning a scripting language.
  • Writers and content creators drafting by voice who don't want their drafts indexed.
  • Academics and ESL users who think faster than they type and want their speech kept private.
