How to install perplexity on Debian 13

Perplexity AI doesn’t offer an official native Linux client, but on Debian 13 you can run it smoothly as a desktop application using a lightweight AppImage wrapper. This method gives you a standalone app with proper desktop integration, without relying on a browser tab.

Step 1: Update the System

Start by updating Debian 13 to avoid dependency issues.

sudo apt update && sudo apt upgrade -y

Step 2: Install Required Dependencies

The Perplexity desktop AppImage requires basic tools and FUSE support.

sudo apt install -y wget curl libfuse2

libfuse2 is required for running AppImage files on Debian.

Step 3: Download Perplexity AI Desktop App

The most reliable Linux build is available 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

Give execution permission to the AppImage file:

chmod +x Perplexity-AI.AppImage

Step 5: Run Perplexity AI

Launch the application:

./Perplexity-AI.AppImage

Perplexity AI will open as a standalone desktop app, fully independent from your browser.

Step 6: Create a Desktop Launcher

Add Perplexity to the application menu.

Create a desktop entry:

nano ~/.local/share/applications/perplexity-ai.desktop

Paste the following content:

[Desktop Entry]
Name=Perplexity AI
Comment=AI-powered search and research assistant
Exec=/opt/perplexity-ai
Icon=utilities-terminal
Terminal=false
Type=Application
Categories=AI;Utility;

Save and exit.

Update the application cache:

update-desktop-database ~/.local/share/applications/

Perplexity AI will now appear in your desktop launcher.

Optional Step: Notes on Security and Networking

This app is a wrapper for https://www.perplexity.ai
All communication is encrypted over HTTPS
Works fine behind VPNs, proxies, and Clash-based setups
Can be sandboxed further using Firejail if needed

If you prefer a browser-based approach, installing Perplexity as a PWA via Chromium also works — but the AppImage method provides better desktop isolation and a more native feel on Debian 13.
