About

ThinkRail is a desktop app, and a browser view through its CLI, that wraps the pi coding agent in isolated git-worktree workspaces. It provides editors, a file tree, terminals, several concurrent agent chats, and SPEC.md files that the agent reads and maintains. It connects to MCP servers from a pi mcp.json file and signs in with JetBrains AI or any provider that pi supports.

Use cases: coding, code-generation, agent-orchestration
