JetBrains ThinkRail is an agent IDE built on pi, with isolated workspaces

JetBrains Thinkrail

JetBrains ThinkRail is an IDE built around the pi coding agent. It keeps project knowledge in isolated workspaces, spec files maintained alongside the code, and reusable skills. It supports parallel tasks on git worktrees, GitHub PR management and MCP connections. Full extension support is still planned.

Why it matters: ThinkRail runs parallel agent tasks in isolated workspaces and keeps project intent in spec files maintained with the code, so context doesn't have to be restated each session.
