About Pi
Pi.dev is the online source and repository for documentation on Pi, a lightweight, free artificial intelligence software agent terminal harness built by Earendil Inc. The software was founded by Mario Zechner, a software engineer, and operates within the Earendil Inc. corporate entity.
The website provides installers for downloading the Pi terminal on Unix-based and PowerShell systems. It contains guides and documentation for Pi Durable and other features. The site also lists updates in its changelog, provides press kit materials, and documents the large language model providers—such as Anthropic, OpenAI, Google, and OpenRouter—that the software supports.
Within a terminal user interface, Pi performs file-reading and -writing operations and executes Bash shell commands through an artificial intelligence agent loop. Developers can extend the harness with functionality such as TypeScript extension modules, prompt templates, themes, and artificial intelligence skills through npm or Git.
Pi is available under the MIT license and is managed by the GitHub organization earendil-works.
