Frequently Asked Questions

Everything you need to know about VaulType.

What is VaulType?

VaulType is a privacy-first, macOS-native speech-to-text application. It uses local AI models (whisper.cpp and llama.cpp) to convert your voice into text directly on your device, with no cloud processing.

Is VaulType free?

Yes! VaulType is completely free and open source under the GPL-3.0 license. No subscriptions, no freemium tiers, no hidden costs.

Does it work offline?

Absolutely. VaulType is designed with a zero-network architecture. All speech recognition and text processing happens locally on your Mac. No internet connection is ever required.

What languages are supported?

VaulType supports 90+ languages through Whisper's multilingual models (such as small, medium, and large-v3). English-only models are optimized for speed if you only need English. Language detection is automatic — just speak and VaulType recognizes the language.

What are the system requirements?

macOS 14 (Sonoma) or later. Apple Silicon (M1/M2/M3/M4) recommended for GPU acceleration. Minimum 8 GB RAM, 16 GB recommended for optimal performance with larger models.

How does privacy work?

Your voice data never leaves your device. VaulType processes everything using on-device AI models — no cloud APIs, no data transmission, no telemetry. Audio recordings are processed in memory and discarded — only the resulting text is stored locally in your history.

What are the processing modes?

VaulType offers 6 modes: Raw (exact transcription), Clean (grammar/spelling fixes), Structure (organized bullet points), Prompt (AI prompt formatting), Code (code comments/docstrings), and Custom (your own templates).

Can I use VaulType with any app?

Yes. VaulType uses macOS accessibility APIs to inject text directly at your cursor position in any application — text editors, terminals, browsers, IDEs, email clients, and more.

How do voice commands work?

VaulType recognizes special voice command prefixes to launch applications, manage windows, and control system functions. Say things like "Launch Safari" or "Minimize window" while VaulType is listening.

How do I choose the right Whisper model?

Start with the "small" model for the best balance of speed and accuracy. Use "tiny" or "base" for faster results on shorter audio, or "large-v3" for maximum accuracy on complex audio. Larger models need more RAM.

Your voice stays private. Text appears at your cursor.
