About Pi

Pi is an open-source AI agent toolkit built by Earendil Works that bundles a unified multi-provider LLM API, a tool-calling agent runtime with state management, and an interactive coding agent CLI into one npm-installable package. The `@earendil-works/pi-ai` package abstracts OpenAI, Anthropic, Google, and other providers behind a single interface; `@earendil-works/pi-agent` provides the runtime that orchestrates tool calls and conversation state; and `@earendil-works/pi-coding-agent` ships as a ready-to-use CLI that can be extended with new skills. The project is a monorepo hosted on GitHub with a Discord community and documentation at pi.dev, positioned as a developer-friendly foundation for building custom coding and non-coding agents.

Key Features

Unified Multi-Provider LLM API: `pi-ai` exposes OpenAI, Anthropic, Google, and other providers behind a single API so agents can swap models freely.
Agent Runtime with Tool Calling: `pi-agent` handles tool calls, state management, and the core agent loop developers would otherwise rewrite.
Self-Extensible Coding Agent: `pi-coding-agent` is a ready-to-use CLI that developers can extend with their own tools and skills.
Terminal UI: Ships an interactive TUI so developers can work with the coding agent directly in the terminal without a heavy IDE.
npm-Distributed Packages: Everything ships as scoped npm packages, so installation and upgrades follow standard JavaScript tooling.
Documented and Community-Backed: Full documentation at pi.dev/docs plus an active Discord community for support and contributions.

Use Cases

Building a Custom Coding Agent: Developers fork pi-coding-agent to build a company-specific coding assistant with proprietary tools.
Cross-Provider Prototyping: Teams use pi-ai to test the same agent against OpenAI, Anthropic, and Google models without rewriting code.
In-Terminal AI Workflow: Solo developers run the pi TUI to keep their AI agent alongside their shell instead of a separate IDE panel.
Agent Runtime Foundation: Startups adopt pi-agent as the tool-calling and state layer under their own product agent.
Learning Agent Architecture: Engineers new to agent development study the pi monorepo as a clean reference implementation.
Extending With Custom Skills: Teams add domain-specific skills to the coding agent to automate repetitive workflows.
