What is it?

Jarvis is a macOS voice assistant centered on dictation. You hold the Fn key, speak, and release it; the app transcribes the audio, removes filler words, fixes grammar, and inserts the resulting text into whatever app has focus. It can also rephrase or reformat text and run small actions such as opening a website or setting a timer.

Transcription can run fully offline using local Whisper models or NVIDIA Parakeet through Sherpa-ONNX. For post-processing, it supports local LLMs through Ollama, or a cloud setup using Deepgram for speech-to-text and Gemini for text cleanup. Prompts that control formatting and assistant behavior can be customized.

The app is distributed as a signed and notarized DMG for Apple Silicon and Intel Macs, with an iOS version available through TestFlight. It is built with TypeScript and Node.js, and the source can be built locally with npm. A Windows version is listed on the roadmap but not yet available.

  • Build from source requires Node.js 18+, macOS 10.13+ and Xcode CLI tools.
