Engineering Architecture·macOS In Active Testing

Roadmap & OS Architecture.

We maintain strict technical honesty: macOS is currently our sole active desktop prototype. Below is the multi-platform engineering roadmap for Windows, iPhone, and Android.

macOS

Prototype / early access

Operating System Architecture Comparison

How Project Vaani hooks into native OS input pipelines and hardware accelerators.

Layer / Mechanism	macOS	Windows	iPhone (iOS)	Android
Development Status	Prototype / Early Access	In Planning	Planned	Planned
Global Shortcut	Option+Space (Customizable)	RegisterHotKey API (Win+H hooked)	Action Button / Back Tap	Quick Settings Tile / Power Tap
Text Injection	AppleScript + Sentinel Clipboard	SendInput / UI Automation	Keyboard Extension API	InputMethodService / Bubble
Local AI Inference	whisper.cpp + Ollama (Metal)	Local models (planned)	CoreML models (planned)	On-device models (planned)
Floating HUD Overlay	Floating Audio Notch	System Tray / Border HUD	Dynamic Island / In-App Overlay	Accessibility Bubble
Transform Mode (⌥O)	Active (Accessibility API)	Planned (UI Automation)	Planned (Share Sheet / Action)	Planned (Text Selection Action)

Local-First By Design

We prioritize quantized on-device inference using whisper.cpp and local LLM runners. Your spoken thoughts and dictionary stay strictly local when local mode is enabled.

Native Input Injections

Rather than forcing work into a siloed web app, Vaani injects directly into existing cursors in Xcode, Cursor, VS Code, Superhuman, Slack, Linear, and Notion.

Transparent Telemetry

The desktop app does not send speech bytes to third parties in local mode. The marketing website uses aggregate, cookieless Vercel Web Analytics strictly for page performance.
