This is an AI IDE built around the pi coding agent. It provides a Monaco editor, file tree, terminal, and diff view, and creates a separate Git worktree workspace for each task, allowing multiple agents to work in parallel without affecting the main branch. It preserves long-term project knowledge for agents through a SPEC.md specification file in the project, supports MCP, Agent Skills, and GitHub PR workflows, and is available as both a desktop app and in the browser, with a built-in Simplified Chinese interface.
