ThinkRail is a JetBrains incubator project that wraps the ‘pi’ coding agent in a thin host application. It provides a mobile-first UI with a tabbed Monaco editor, git worktree workspaces, terminals, and concurrent chat sessions for the agent. The agent owns models, skills, compaction, and session state, while the app handles the workspace, editor, and wire protocol. It ships as a native desktop installer and a self-contained CLI that opens the same app in a browser.
