View prompt
Open <repo> in JetBrains/thinkrail, create two workspaces, and have one agent implement <task> with approach A and the other with approach B. Compare the diffs and test results, then tell me which branch to merge and why.
- REPO
-
Keep project intent alive across agent sessions with living specs
Let the agent read and maintain a connected graph of SPEC.md files beside your code.

View prompt
In JetBrains/thinkrail, set up living specs for <repo>: write SPEC.md files for the main modules with their purpose and key decisions, link them into a graph, and keep them updated as you implement <feature>.
- REPO
-
Review agent changes and ship the pull request from one window
Leave anchored review comments, hand them to the agent and open the PR with its CI checks in view.
View prompt
In JetBrains/thinkrail, review the changes in this workspace, leave anchored comments on anything unclear, have the agent fix them, then open a GitHub PR described from the plan and commits and report the CI status.
Quick start with Thinkrail
- Check you have what it needs: macOS, Linux or Windows (Linux needs the GTK and WebKit libraries listed in the README); A git repository; JetBrains AI sign-in or a provider connected through pi's own auth.
- Open JetBrains/thinkrail on GitHub and read the README and license.
- Install on macOS or Linux with
curl -fsSL https://raw.githubusercontent.com/JetBrains/thinkrail/main/install.sh | bash - Open a repo with
thinkrail ~/code/my-repo - Create two or more workspaces from the project; each becomes a git worktree with its own branch
- Start a pi chat in each workspace with the approach you want it to try
These steps come from our top use case, Run parallel coding agents in isolated git worktrees, which also has a copy-paste agent prompt.

Questions about Thinkrail
What is Thinkrail?
ThinkRail is JetBrains' agentic IDE built around the pi coding agent. It cuts isolated git worktree workspaces so agents work in parallel without touching your checkout, wraps them in a real IDE (Monaco editor, file tree with git marks, terminals), keeps durable project knowledge in a graph of living SPEC.md files, reads your existing Agent Skills and connects MCP servers, with JetBrains AI or your own provider credentials. It is an open-source project on GitHub: https://github.com/JetBrains/thinkrail.
How do I use Thinkrail?
Install on macOS or Linux with curl -fsSL https://raw.githubusercontent.com/JetBrains/thinkrail/main/install.sh | bash; then open a repo with thinkrail ~/code/my-repo; create two or more workspaces from the project; each becomes a git worktree with its own branch.
