How to install perplexity on Centos 9

Perplexity AI doesn’t ship an official Linux client, but you can run it cleanly on CentOS 9 using an AppImage-based desktop wrapper. This gives you a standalone desktop app with menu integration and no browser dependency.

Step 1: Update the System

Start with a fully updated CentOS 9 system.

sudo dnf update -y

Step 2: Install Required Dependencies

CentOS needs FUSE and basic tools to run AppImage files.

sudo dnf install -y wget curl fuse fuse-libs

Verify FUSE is available:

lsmod | grep fuse

If nothing shows, load it:

sudo modprobe fuse

Step 3: Download Perplexity AI Desktop App

The most stable Linux build is hosted on SourceForge.

Move to a temporary directory:

cd /tmp

Download the AppImage:

wget https://downloads.sourceforge.net/project/perplexity-ai-desktop-app/Perplexity-AI.AppImage

Step 4: Make the App Executable

chmod +x Perplexity-AI.AppImage

Step 5: Run Perplexity AI

Launch it directly:

./Perplexity-AI.AppImage

Perplexity AI will open as a standalone desktop application.
