Download for Windows

v1.0.2 · MSI · Release notes

Double-click the MSI to install for your user account, then open Comark from the Start menu. Run the self-check first and approve UAC if the firewall check fails. Not code-signed yet, so Windows may still ask you to confirm.

Both Mac and Windows companions require an iPad with Comark installed. They cannot be used on their own.

Comark for iPad is available on the App Store, with Apple speech recognition by default and Comark Pro subscriptions or a one-time purchase. The iPhone version is coming soon.

Or let your AI agent install it

Paste one command into your AI agent (Codex, Claude Code, etc.) or a terminal, and it downloads and installs the right companion for you.

Maccurl -fsSL https://comark.work/install.sh | sh
Windows (PowerShell)irm https://comark.work/install.ps1 | iex

macOS may ask for your password to install into Applications; on Windows the command installs the MSI and SmartScreen may confirm before first launch.

A few things to know.

Which mobile devices can I use?

Comark is available now for iPad on the App Store. Install it, then pair with a Mac or Windows companion. The iPhone version is coming soon. Desktop downloads alone do not provide the full workflow.

What is inside the downloads?

Mac: a ZIP containing ComarkMac.app. Windows 1.0.2: an MSI installer that installs Comark for your user account and adds it to the Start menu. Both are unsigned builds.

Do I need a GitHub account? Is the app open source?

No account needed to download. The public repo has only product info and release packages. All source code remains private.

Where do screenshots and voice recordings go?

Screenshots transfer over local network between paired devices. Voice dictation sends audio to your configured provider, which may require an account and charge fees.
