Think Rail is an agentic IDE that improves with use, learning projects through living specs and building capabilities over time. Built around the picoding agent, it isolates work into separate git worktree workspaces with durable project knowledge.
Key features include isolated workspaces where you can open any git repo and create workspaces from it, each with its own branch and working directory. The topbar shows branch status against origin with one-click actions like publish, push, or open PR. Once a PR is open, it displays CI checks and lets you mark it ready, merge, or delete the remote branch.
The real IDE interface includes Monaco editor tabs, Files tree with live git change marks, terminals, and documents — all scoped to the active workspace. Chats stream like the engine thinks with several concurrent pi sessions per workspace, each showing live token and cost readouts.
