Notarized macOS installer, signed with Developer ID, and ready to install outside the App Store.

Powered by your ChatGPT

Uses your existing ChatGPT subscription through OpenAI's Codex. No extra accounts needed.

Native macOS experience

Menu bar app with global shortcuts, Apple voice integration, and macOS Keychain for key storage.

Voice modes

Local Voice

Uses Apple's built-in speech recognition and text-to-speech on your Mac. Completely private — no audio leaves your device. No API key needed.

Cloud Voice

Uses OpenAI transcription and GPT TTS for natural speech. Requires your own OpenAI API key, stored securely in macOS Keychain.

Installation

  1. 1

    Download the installer

    Grab the signed PKG from the official GitHub release. It is the cleanest path and the one we support publicly.

  2. 2

    Install and open Orbit

    The installer places Orbit in Applications and opens it for you, so setup starts immediately instead of leaving you in Finder.

  3. 3

    Approve permissions

    Grant Screen Access, Accessibility, and Microphone so Orbit can see your screen, point at controls, and respond naturally.

  4. 4

    Connect and choose voice

    Orbit reuses your existing ChatGPT auth when available or opens a quick login. Then choose Local Voice or Cloud Voice and start talking.

Under the hood

gpt-5.4-mini

Default model for all Codex actions. Fast, capable, and optimized for desktop assistant tasks.

Push-to-talk

Global shortcut to activate Orbit from anywhere. Hold to speak, release to send.

Dual speech engines

Apple Speech for local privacy, OpenAI transcription plus GPT TTS for cloud quality. You choose.

Keychain storage

API keys and credentials stored in macOS Keychain — never in plain text files.
