Installation

Coeus runs on macOS, Linux, and Windows.

macOS

1. Go to usecoeus.com/download
2. Download the .dmg file: there are two versions, one for Apple Silicon (M1 and later) and one for Intel Macs. If you're not sure which you have, check Apple menu → About This Mac.
3. Open the .dmg file and drag Coeus into your Applications folder
4. Open Coeus from Applications

macOS might ask if you're sure you want to open it the first time. That's normal for apps not from the App Store. Click Open.

Linux

Download from usecoeus.com/download and pick the format for your distro:

Format	Works on
.AppImage	Any Linux distro
.deb	Ubuntu, Debian, and derivatives
.rpm	Fedora, RHEL, openSUSE

AppImage

Make it executable and run it:

chmod +x Coeus_*.AppImage
./Coeus_*.AppImage

.deb

sudo dpkg -i coeus_*.deb

.rpm

sudo rpm -i coeus_*.rpm

Windows

Download from usecoeus.com/download and choose the installer that fits how you manage the machine:

Format	Best for
.exe	Normal installs on a personal machine
.msi	Admin, enterprise, silent, or managed deployment

.exe

1. Download the Windows installer
2. Open the .exe file
3. Follow the installer prompts
4. Launch Coeus from the Start menu or desktop shortcut

.msi

Use the .msi package if you deploy software with Group Policy, MDM, or other Windows management tooling.

What Coeus needs

Coeus runs entirely on your machine. There's no account to create during installation. You connect an AI provider later (or not at all: basic notes and search work without one).

	Minimum
macOS	13 Ventura or later
Linux	Any modern x86_64 distro
Windows	Windows 10 or later
RAM	4 GB
Disk	500 MB free (more if you download local AI models)

After installing

Once it's installed, run through the setup wizard. It takes about two minutes and gets you to a working setup.
