- Your real desktop, not a VM: macOS 14+ (Apple Silicon and Intel) and Windows x64/ARM64.
- Reads before it clicks: Accessibility/UIA controls, Apple Vision or Windows OCR, and per-window screenshots with zoom. Clicks are given in the screenshot’s pixel space and mapped back to the screen.
- Types any text: full Unicode keyboard input, including Chinese, Japanese, Korean and emoji.
- Accessibility-first control (v0.3.0): AX-first

This recording shows Nova’s browser tool path (fixture page and real MCP
navigation/click calls). It was captured on Linux, so it does not show native
macOS/Windows desktop control or model reasoning. The reproduction notes explain
the --npx adapter and isolated browser.
Install
| Platform | Published v0.3.0 |

| macOS 14+ (manual) | nova-v0.3.0-universal-apple-darwin.tar.gz from Releases |
| Windows x86_64 | nova-v0.3.0-x86_64-pc-windows-msvc.zip |
| Windows ARM64 | nova-v0.3.0-aarch64-pc-windows-msvc.zip |

Homebrew (macOS):
brew tap bigduu/tap
brew install bigduu/tap/nova
nova --version
The formula installs the CLI from the release archive. It does not configure an
MCP client or grant macOS permissions. Run which nova to find the path to use
below: usually /opt/homebrew/bin/nova on Apple Silicon and
/usr/local/bin/nova on Intel Macs.
npm (macOS and Windows): Homebrew stays the recommended macOS install.
@bigduu/nova (package version 0.3.1) is a Node launcher that downloads the
