Frequently Asked Questions
How is Subwright different from online transcription services?
Subwright runs entirely on your device. Your audio files and transcripts are never uploaded to the cloud, so you keep full control over sensitive meetings, medical notes, or confidential interviews. You also avoid per-minute fees and internet dependency.
Do I need to download transcription models separately?
Yes. On first launch, Subwright guides you to download a model to your local machine:
- Whisper: from tiny to large-v3-turbo
- Qwen3-ASR: 0.6B (free) and 1.7B (Pro)
This lets you balance speed and accuracy. You can also import custom models via deep link.
Which languages and platforms are supported?
Subwright supports macOS 11+ (Intel & Apple Silicon) and Windows 10/11. The UI is available in 9 languages, and Whisper transcription supports 99+ languages.
Can I use Pro on multiple devices?
Yes. A Pro license supports multiple device bindings. You can unbind old devices anytime in Settings when switching machines.
