What is Pi?
Pi is a minimalist, open-source AI coding agent that runs entirely within your terminal, circumventing the security risks associated with cloud-dependent SaaS wrappers. Engineered by Earendil Works, it operates seamlessly with over 15 model providers, allowing developers to execute secure local orchestration using Ollama, Llama.cpp, or direct API integrations. Unlike bloated IDE extensions, Pi ships with a constrained default toolset—reading, writing, editing, and executing shell commands—giving users total architectural control. By leveraging a modular ecosystem of skills, extensions, and prompt templates, it fundamentally transforms developer productivity and workflow automation without compromising strict enterprise compliance. Delivering an unparalleled user experience for CLI power-users, it represents the ultimate sandbox for engineers who demand absolute data sovereignty.
How to use Pi?
To get started with Pi, first install the CLI globally via npm using 'npm install -g @earendil-works/pi-coding-agent' or launch it instantly with Ollama via 'ollama launch pi'. Once installed, configure your preferred model providers and API keys in the '~/.pi/agent/models.json' file, ensuring your workspace is tailored to either local or cloud endpoints. Finally, type 'pi' in your terminal to initialize the interactive TUI, where you can install custom extensions, deploy specific skills, and immediately command the agent to read, edit, or write code within your local directories to maximize efficiency.
Pi's Core Features
Terminal-First Architecture: Command your AI assistant entirely from the command line interface without relying on browser-based or SaaS dashboards.
Extensive Model Support: Connect seamlessly to over 15 AI providers, including Anthropic, OpenAI, and local runners like Ollama, granting ultimate flexibility.
Customizable Workflows: Tailor the agent strictly to your needs by utilizing modular extensions, reusable prompt templates, and installable skills.
Strict Data Sovereignty: Ensure absolute data compliance and security by running the agent on air-gapped workstations or regulated corporate enclaves.
Multi-Agent Orchestration: Enable direct two-way, peer-to-peer communication between multiple Pi agents to accomplish complex engineering tasks collaboratively.
On-the-Fly Adaptability: Prompt the agent to dynamically build its own UI tweaks, workflows, or commands mid-session to solve edge-case problems instantly.
Session Tree Navigation: Branch, bookmark, and share complex chat session trees to effortlessly restore historical context or experiment with different prompts.
