Open Source Whisper: local, privacy-first voice-to-text
About OSW
HAVEN Intelligence built OSW to demonstrate that AI tools do not need to be expensive cloud services. OSW runs locally with OpenAI's Whisper models and reflects our focus on practical, accessible AI solutions.
The concept is simple: press a hotkey, speak, and text appears at the cursor. All inference happens locally on the user's machine. No data is sent to the cloud, no subscription is required, and no telemetry is collected.
How It Works
OSW uses faster-whisper with int8 quantization to run OpenAI's Whisper models efficiently on standard hardware. The result is voice-to-text that works without an internet connection.
Step 1
Activate with hotkey
OSW runs in the system tray and listens for a global hotkey. A single press starts recording, regardless of which application is in the foreground.
Step 2
Local inference
The audio recording is processed locally with faster-whisper. No data leaves the machine. Users choose between five quality tiers, from the smallest model at 336 MB to the largest at 3 GB.
Step 3
Text at cursor
The transcribed text is automatically inserted at the cursor position in the active application. No copying, no switching between windows.
