Slumbr 1.0.0 — local, offline voice-to-text for Windows

Tap Caps Lock, speak, tap again — your words type into whatever window is focused. Fully on-device: no accounts, no cloud, no telemetry.

Download

Installer For Notes
slumbr-setup-cpu.exe Any PC Runs on every x64 Windows machine (NVIDIA / AMD / Intel / no GPU). CPU-speed. Bundles its models — works offline the moment it's installed. Start here if unsure.
slumbr-setup-nvidia.exe NVIDIA GPU GPU-accelerated (CUDA). Bundles the CUDA runtime + the live-preview models; downloads the GPU transcription model (~1.5 GB) once on first launch.

"Windows protected your PC"? Slumbr is open-source and not code-signed yet, so SmartScreen warns on first run — click More info → Run anyway. Or install from source (see the README) for AMD/Intel GPU acceleration.

If a build doesn't match your GPU, Slumbr runs on its built-in CPU engine and points you at the right build — it never leaves you stuck.

Highlights

  • One-click installers that work on any PC, plus a from-source path that auto-detects your hardware (NVIDIA CUDA · AMD/Intel DirectML · CPU).
  • Offline first run — the CPU build ships its speech models inside the installer, so there's nothing to download before you can dictate. (The NVIDIA build downloads its GPU model once on first launch.)
  • Live partials while you speak (Moonshine + Silero VAD + online punctuation) and an accurate final transcribe from your chosen backend.
  • Tap-to-toggle hotkey (rebindable), auto-paste at the cursor, and copy-from-History (in-memory only — nothing about your dictations is written to disk).
  • Mute other apps while dictating (VB-Cable routing — Discord/Zoom/Teams/OBS/browser calls).
  • Resilient startup: if a GPU backend can't load on your machine, Slumbr falls back to the CPU engine instead of failing.
  • 100% offline at runtime — after the one-time setup, nothing leaves your machine.

Requirements

Windows 10/11 (64-bit). GPU optional — the CPU build runs anywhere. Full details in the README.

Full changelog: see CHANGELOG.md.
