Overview

My personal AI desktop tool, rebuilt from the native-Swift VOX into a Rust + Tauri app so it isn't tied to one platform and the engine layer is genuinely pluggable. It runs on macOS today; Windows/Linux builds compile and are CI-tested but their runtime isn't finished.

It replaced several paid subscriptions for me — speech-to-text, LLM text cleanup, and meeting notes — in one place, with the option to run everything locally.

Features

Features

  • Rewrite selected text on a hotkey.
  • Dictation: transcribe on pause, LLM cleanup, paste at cursor.
  • Meeting notes: record mic + system audio, then LLM summary you can chat with.

Design

  • 6-crate Rust workspace; pluggable LLM/STT/TTS engines (OpenAI or local whisper-rs/sherpa-onnx).
  • 63 Tauri commands; macOS Accessibility, ScreenCaptureKit, and Keychain integration.
