AI-Powered Package Manager for Debian/Ubuntu
Install software using natural language. No more memorizing package names.
Quick Start • Features • Usage • Architecture • Contributing • Community
Cortex is an AI-native package manager that understands what you want to install, even when you don't know the exact package name.
# Instead of googling "what's the package name for PDF editing on Ubuntu?"
cortex install "something to edit PDFs"
# Instead of remembering exact package names
cortex install "a lightweight code editor with syntax highlighting"
# Natural language just works
cortex install "tools for video compression"
| Feature | Description |
|---|---|
| Natural Language | Describe what you need in plain English |
| Dry-Run Default | Preview all commands before execution |
| Sandboxed Execution | Commands run in Firejail isolation |
| Full Rollback | Undo any installation with cortex rollback |
| Audit Trail | Complete history in ~/.cortex/history.db |
| Hardware-Aware | Detects GPU, CPU, memory for optimized packages |
| Multi-LLM Support | Works with Claude, GPT-4, or local Ollama models |
# 1. Clone the repository
git clone https://github.com/cortexlinux/cortex.git
cd cortex
# 2. Create virtual environment
python3 -m venv venv
source venv/bin/activate
# 3. Install Cortex
pip install -e .
# 4. Configure API key
echo 'ANTHROPIC_API_KEY=your-key-here' > .env
# 5. Verify installation
cortex --version# Preview what would be installed (safe, no changes made)
cortex install nginx --dry-run
# Actually install
cortex install nginx --execute# Install with natural language
cortex install "web server for static sites" --dry-run
cortex install "image editing software like photoshop" --execute
# View installation history

Cortex is designed with security as a priority:
| Protection | Implementation |
|---|---|
| Dry-run by default | No execution without --execute flag |
| Sandboxed execution | All commands run in Firejail containers |
| Command validation | Dangerous patterns blocked before execution |
| Audit logging | Every action recorded with timestamps |
| Rollback capability | Full undo support for all installations |
| No root by default | Sudo only when explicitly required |

"ANTHROPIC_API_KEY not set"
# Verify .env file exists
cat .env
# Should show: ANTHROPIC_API_KEY=sk-ant-...
# If missing, create it:
echo 'ANTHROPIC_API_KEY=your-actual-key' > .env"command not found: cortex"
# Ensure virtual environment is activated
source venv/bin/activate
# Reinstall
pip install -e ."Python version too old"
# Check version
python3 --version
# Install Python 3.11 on Ubuntu/Debian
sudo apt update
sudo apt install python3.11 python3.11-venv
# Create venv with specific version
python3.11 -m venv venvpip install fails
# Update pip
pip install --upgrade pip
# Install build dependencies
sudo apt install python3-dev build-essential
# Retry installation
pip install -e .Alpha Release - Cortex is under active development. APIs may change.
