Offline Voice to TextOptimized for Windows 10 & 11.
Universal push-to-talk dictation running locally on your NVIDIA, AMD, or Intel GPU via DirectML. Zero cloud streaming, sub-200ms latency.
The Problem with Cloud Dictation
Windows Speech Recognition and cloud alternatives either provide poor accuracy, upload voice data to remote servers, or fail to paste properly into elevated Win32 and developer applications.
Physical Hardware Sovereignty
Murmur integrates DirectML and native Windows SendInput/UIAutomation APIs to deliver smooth, reliable dictation into Cursor, PowerShell, Word, and Slack without cloud lag.
Local Architecture vs. Cloud SaaS
| Buyer Concern | Murmur (Local-First) | Cloud Alternatives (e.g. Wispr) |
|---|---|---|
Windows Hardware Acceleration Decodes 5x faster with minimal CPU overhead | DirectML & CUDA GPU offloading | CPU-only or cloud streaming |
Elevated App Text Injection Reliable text paste across all your desktop tools | Native SendInput with UIPI elevation fallback | Fails silently in Task Manager / IDEs |
Windows System Menu Conflicts Smooth, frustration-free Alt+Space experience | Suppresses SC_KEYMENU conflicts automatically | Triggers Windows system menus inadvertently |
Offline Functionality Dictate in secure enterprise environments | 100% offline (No Microsoft cloud telemetry) | Dependent on cloud connection |
Harness your discrete or integrated GPU without cloud subscriptions.
Whether you run an NVIDIA RTX GPU, AMD Radeon, or Intel Iris Xe, Murmur runs Whisper directly on your hardware at full speed without monthly fees.
“Finally a Windows dictation app that handles code terms and doesn't route my mic through cloud servers. Alt+Space is instant.”
